Description

The present invention relates to a method for producing water-soluble, filled hollow body, which, before the shell material is formed into a hollow body, undergo a stretching step of the shell material containing an agent, in particular a washing, care and / or cleaning agent.

The use of water-soluble packaging in a wide variety of industrial applications is already part of the state of the art. As a rule, the water-soluble packaging materials encase chemicals or consumer goods that are to be protected from the environment by the packaging, but at the same time also protect the consumer or consumer from direct contact with the packaged goods. In agrochemicals, the use of pesticides in water-soluble bags, which were produced by a thermoforming process, from the European patent application EP 0 608 910 A1 known. The water-soluble packaging protects the user from exposure to the toxic chemicals and also simplifies the dosing of the pesticides by simply adding a pesticide bag to a given amount of water in which the bag and its contents dissolve. The use of water-soluble packaging forms is also known in the pharmaceutical industry, for example, capsules containing water-soluble hard gelatin containing pharmaceutical preparations are administered to the consumers or patients.

Recently, the use of water-soluble packaging has also established itself in the field of detergents and cleaners in the market. The consumer is here in particular single-dose amounts of detergents and cleaners, which are packaged in plastic bags, offered. The consumer is thereby enabled a convenient and simple dosage of detergents and cleaners, since the products are already present in pre-portioned form. The advantages of such individual portions are in particular due to the fact that the consumer is spared tearing open the packaging, thereby conveniently dosing a single, sized for a washing and cleaning portion by inserting the bag directly into the washing machine or dishwasher, especially in their Einspülkammer or by throwing the bag into a certain amount of water, for example in a bucket, a bowl or in the hand-washing or -spülbecken possible. The foil bag surrounding the washing, cleaning agent or care agent portion dissolves on reaching a certain temperature. Detergents and cleaning agents packaged in bags of water-soluble film are described in large numbers in the prior art. Thus, the German patent application discloses DE 198 31 703 A1 a portioned detergent or cleaning agent preparation in a bag of water-soluble film, in particular in a bag of (optionally acetalized) polyvinyl alcohol, wherein at least 70 wt .-% of the particles of the detergent or cleaning agent preparation have particle sizes greater than 800 microns. Although such film bags are very consumer-friendly and facilitate dosing, but are not in all cases the appropriate form for dosing detergent, cleaning products and care preparations. The bagged consumer goods in particular has the disadvantage that the foil bags are very sensitive to mechanical influences. During transport or handling, this can lead to unwanted product leakage if the film is damaged by carelessness. Just touching with pointed or cracked fingernails can already lead to damage and thus to an undesirable consumer budget frustration. Furthermore, it has proven to be extremely difficult to achieve a high degree of filling of the foil bags. The higher the degree of filling of the water-soluble portions, the higher the risk of contamination of the sealed seams, which in turn leads to leaky sealing seams and thus to product leakage, in particular in the case of liquid formulations. can lead. Due to the low degree of filling and possibly due to film-induced instability, the film bag also have no elastic dimensional stability. When exposed to a deformation force, the bags of deformable films in the unfilled and filled state no longer assume their original shape, that is to say before the action of force, on their own. The mechanical properties of such "floppy" bags are often not reproducible and therefore extremely difficult to stack or re-pack on a commercial scale. In addition, plump and flexible elastic water-soluble portions experience a much higher consumer acceptance, since a stronger impression of a soft wash and cleaning agent also forms to the laundry. In addition to the advantageous aesthetic aspects, which plays an important role for the consumer, especially in the consumer goods sector, the reproducibility creates a recognizable product design. Impact-filled washing, cleaning and care product tablets also have better mechanical load and deformability values.

Methods for the production of foil bags, in particular by the thermoforming method, are already extensively described in the prior art. The pamphlets WO 00/55068 A1 . WO 00/55046 A1 . WO 00/55045 A1 . WO 00/55044 A1 . WO 00/55415 A1 and WO 02/16207 A1 describe thermoforming Process for producing water-soluble sachets which undergo a deep-drawing step. For this purpose, a thermoformable water-soluble film is first drawn into a cavity, the formed mold then filled and covered in a further step with a second film and sealed.

However, a disadvantage of the abovementioned thermoforming process is not only the problem of contamination of the film surfaces to be sealed and the associated susceptibility to leakage of the portions, but also the relatively high consumption of the film material for the sealing areas.

Processes which have a low consumption of wrapping material, in particular in the sealing area, are blow-molding processes, as used in the WO 01/64421 A1 to be discribed. For this purpose, a tubular preform is extruded into a two-part mold, the mold closed in the bottom area, the preform is blown into the cavity of the mold, filled and sealed. A disadvantage of this method is the high wall thickness of the wrapping material, which occurs in particular in the sealing area of the bottom, because a further high requirement, in particular for water-soluble packagings filled with detergents, care and / or cleaning agents, is a high dissolution rate of the wrapping material low temperatures, such as 30 ° C or 40 ° C. Are sub-areas, such as sealing seams afflicted with high wall thicknesses, this leads to undissolved or partially dissolved residues that leave visible stains on textiles especially when using the water-soluble packaging in the textile care.

The object of the invention was therefore to provide a technically simple method for producing water-soluble filled hollow body, in particular a detergent, cleaning agent or care-containing portion, which overcomes the aforementioned disadvantages in the prior art, in particular a residue-free dissolution behavior in water even at low temperatures.

Surprisingly, it has now been found that the above object can be achieved by a production method which includes an additional step for stretching the Hüllkörpermaterials.

• a) Bereitstellen eines thermoplastisch verarbeitbaren Materials durch Urformen eines schlauchförmigen Vorformlings, aus einer Blasformmasse, basierend auf einem wasserlöslichen polymeren Thermoplasten,
• b) Recken des Materials durch Klemmbacken in mindestens eine Vorzugsrichtung
• c) Ausbilden eines Hohlkörpers
• d) Füllen des Hohlkörpers mit einem Mittel, vorzugsweise einem Wasch-, Pflege- und/oder Reinigungsmittel
• e) Verschließen des Hohlkörpers.

The invention therefore provides a process for the production of wholly or partly water-soluble filled hollow bodies, comprising an agent comprising the steps:

• a) providing a thermoplastically processable material by prototyping a tubular preform, from a blow molding compound, based on a water-soluble polymeric thermoplastic,
• b) stretching the material through jaws in at least one preferred direction
• c) forming a hollow body
• d) filling the hollow body with an agent, preferably a washing, care and / or cleaning agent
• e) sealing the hollow body.

The process according to the invention for producing completely or partially water-soluble, filled hollow bodies containing an agent comprises as an essential step that first a thermoplastically processable material containing at least one water-soluble thermoplastic is stretched in at least one preferred direction. In the context of the present invention, it has proved to be particularly advantageous if the material provided is stretched in at least one preferred direction, advantageously in a preferred direction. Preferably, the thermoplastic processable material is provided by prototyping a preform, preferably a tubular preform, from a blow molding composition based on a water-soluble polymeric thermoplastic.

It is advantageous if the melt flow index (Melt Flow Index) of the water-soluble polymeric thermoplastic during extrusion, measured in the first step at 10 kg stamping load, between 1 and 30, preferably between 5 and 15, particularly preferably between 8 and 12 and / or the melt flow index ( MFI) of the water-soluble polymeric thermoplastic, measured at 2.16 kg stamping load, between 4 and 40, preferably between 5 and 20, particularly preferably between 8 and 15. In the context of the present invention particularly suitable for blow molding polyvinyl alcohol types are medium to high viscosity and have, for example, MFI values of 6-8 (at 230 ° C, 2.16 kg surcharge, PVA blend manufacturer Texas Polymers "Vinex 2034" or "2144") or 9-11 (at 190 ° C, 10 kg load, PVA blend "TP Vinex 5030").

• a) in einem ersten Schritt mittels Extrudieren ein Vorformling hergestellt
• b) in einem zweiten Schritt in einem Zyklus der Vorformling gereckt und
• c) in einem dritten Schritt der Hohlkörper, vorzugsweise mittels eines Druck stehenden Gases, vorzugsweise Pressluft, und/oder durch Anlegen eines äußeren Vakuums aus Öffnungen einer Kavität heraus geblasen, vorzugsweise zur endgültigen Hohlkörpergeometrie, und
• d) in einem vierten Schritt mit dem Mittel gefüllt und verschlossen, vorzugsweise flüssigkeitsdicht verschlossen, wird.

A particularly preferred method for producing the hollow bodies according to the invention is the blow molding process. This procedure is first

• a) produced in a first step by means of extrusion a preform
• b) in a second step in a cycle of the preform stretched and
• c) in a third step, the hollow body, preferably by means of a pressurized gas, preferably compressed air, and / or by applying an external vacuum blown out of openings of a cavity, preferably to the final hollow body geometry, and
• d) in a fourth step filled with the agent and closed, preferably liquid-tight, is.

By stretching the preform by jaws, the wall thickness of the preform can be significantly reduced, thus also the seal area shows a reduced wall thickness, which dissolves faster.

• a) in einem ersten Schritt ein schlauchförmiger Vorformling hergestellt wird und gereckt wird
• b) in einem zweiten Schritt der Vorformling einseitig verschlossen wird,
• c) in einem dritten Schritt der einseitig verschlossene Vorfomling, mittels eines Druckgradienten, vorzugsweise mittels eines unter Druck stehenden Gases, geblasen wird,
• d) in einem vierten Schritt der vorgeblasene Vorformling ein weiteres Mal, vorzugsweise durch Siegelwerkzeuge, insbesondere beovorzugt durch unter der Blasform angeordnete Klemmbacken, verschlossen wird, und/oder der Hohlkörper, vorzugsweise mittels eines unter Druck stehenden Gases, vorzugsweise Pressluft, und/oder durch Anlegen eines äußeren Vakuums aus Öffnungen der Kavität heraus geblasen, vorzugsweise zur endgültigen Hohlkörpergeometrie, und
• e) in einem weiteren Schritt mit dem Mittel gefüllt und verschlossen, vorzugsweise flüssigkeitsdicht verschlossen, wird.

Further preferred is a method in which first

• a) in a first step, a tubular preform is produced and is stretched
• b) in a second step, the preform is closed on one side,
• c) in a third step, the unilaterally closed preform is blown by means of a pressure gradient, preferably by means of a pressurized gas,
• d) in a fourth step, the pre-blown preform is closed again, preferably by sealing tools, in particular preferably by means arranged under the blow mold jaws, and / or the hollow body, preferably by means of a pressurized gas, preferably compressed air, and / or by Applying an external vacuum blown out of openings of the cavity, preferably to the final hollow body geometry, and
• e) in a further step filled with the agent and closed, preferably liquid-tight, is.

It has proved to be advantageous in the above method when the tubular preform is first closed on one side by means of clamping jaws. Subsequently, the unilaterally closed tube, advantageously inflated by means of compressed air to reduce the wall thickness of the preform. The blown preform can then be reclosed in the blown out area of the preform, by means of a sealing tool, for example clamping or preferably welding jaws. In a preferred embodiment, the preform closed on one side is blown out of openings of the blow mold in a blow mold by means of compressed air and / or by applying an external vacuum, filled with a means and subsequently closed. Preferably, in the production of hollow bodies according to the invention by means of the blow molding process, tubular, preferably water-soluble, preforms are extruded into a mold, preferably into a multipart mold, in particular a two-part mold. The stretching of the material is done by jaws.

• (a) in einem ersten Schritt ein schlauchförmiger Vorformling extrudiert wird,
• (b) in einem zweiten Schritt der Vorformling durch die Hauptform fixiert, vorzugsweise eingeklemmt, wird,
• (c) in einem dritten Schritt der Vorformling durch eine unter dem Formboden plazierte Klemmbacke gereckt wird,
• (d) in einem vierten Schritt der gereckte Vorformling verschlossen wird, vorzugsweise im Bodenbereich der Hauptform verschlossen wird,
• (e) gegebenenfalls in einem weiteren Schritt der Hohlkörper, vorzugsweise mittels eines unter Druck stehenden Gases, vorzugsweise Pressluft, und/oder durch Anlegen eines äußeren Vakuums aus Öffnungen der Kavität heraus geblasen, vorzugsweise zur endgültigen Hohlkörpergeometrie, und
• (f) in einem weiteren Schritt mit dem Mittel gefüllt und verschlossen, vorzugsweise flüssigkeitsdicht verschlossen, wird.

By stretching, the preform loses wall thickness, so that the wall thickness in the sealed area of the stretched preform is considerably lower than without stretching step. In a particularly preferred embodiment of the present invention, the method is performed in that

• (a) extruding a tubular preform in a first step,
• (b) in a second step the preform is fixed by the main form, preferably clamped,
• (c) in a third step, the preform is stretched by a jaw placed under the mold bottom,
• (d) in a fourth step, the stretched preform is closed, preferably closed in the bottom region of the main mold,
• (e) optionally in a further step, the hollow body, preferably by means of a pressurized gas, preferably compressed air, and / or blown out of openings of the cavity by applying an external vacuum, preferably to the final hollow body geometry, and
• (F) filled in a further step with the agent and closed, preferably liquid-tight, is.

In particular, by the step before the formation of the hollow body before stretching step, the provided thermoplastically processable material is diluted so that the welding together or other sealing, for example, by compressing a tubular preform, sealing regions with extremely low wall thickness provides. The achievement of thin wall thicknesses in the sealing area in hollow bodies, which were prepared by a blow molding process, especially in the processing of water-soluble thermoplastics was problematic, on the one hand such materials difficult forms and processing than water-insoluble thermoplastics on the other hand any increased wall thickness range within a hollow body wall deteriorates the solubility.

The hollow bodies produced by the process according to the invention have wall thicknesses in the sealing region of the hollow body of 5 to 800 .mu.m, preferably below 300 .mu.m, more preferably below 200 .mu.m, more preferably between 180 and 10 .mu.m, in particular between 150 and 20 .mu.m, most preferably between 120 and 30 μm, advantageously below 100 μm, particularly advantageously below 80 μm.

Preferably, the ratio of the wall thickness of the sealing area to the wall thickness of the seal seam-free areas is less than 3: 1, preferably less than 2.5: 1, particularly preferably less than 2.0: 1, in particular less than 1.8: 1, more preferably less than 1, 5: 1, advantageously less than 1.2: 1, more preferably less than 1.1: 1.

It has been found in the hollow bodies produced according to the invention that the total dissolution time of the hollow body, in particular in lower temperature ranges, has been considerably reduced.

In a preferred embodiment, the total dissolution time of the hollow body in the convection basin test at 30 ° C below 20 minutes, preferably below 15 minutes, more preferably below 12 minutes, especially below 10 minutes, more preferably below 8 minutes, most preferably below 5 minutes and advantageously below 3 minutes.

To measure and assess the total dissolution time of the hollow body, the hollow body material is tested without content for its residue behavior under specified conditions.

The amount of residue is visually compared to a reference panel and the solubility assessed by means of a score system from 1 (very soluble) to 10 (poorly soluble). The test is carried out with service water (17 ° dH + 2 ° dH) and the following devices:
Digital thermometer Testo 700 of the company Testo GmbH & Co, heating plate of the company Franz MORAT KG (GmbH & Co.) Type: M 22/1, 1000 ml beaker (high form), magnetic stir bar with approx. 4.5 cm length, Stopwatch, filter fabric: single jersey 100% cotton, Fa. Trigema, dark blue, ca. 15 × 15 cm

Execution:

It is cut open a filled hollow body and pushed out the contents. The film thus obtained is divided into 4 approximately equal parts by means of scissors. The beaker is filled with 800 g of service water, the temperature of which is 14 + 1 ° C. It is constantly stirred with the stirring fish, the set stirring speed is between 500-600 revolutions per minute. The 4 pieces of film are now added at the same time in the prepared water and stirred for 15 min. The film residues in the solution are filtered through a fine-meshed dark blue jersey fabric, which is fixed on a 1-liter measuring cup by means of a rubber band. It is then dried at room temperature on a drying rack in the air.

The dried film residue with a grade of 1 (very little residue, film very well soluble) to 10 (a lot of residue, film very poorly soluble) provided.

The dissolution time is determined under the same conditions with setting the desired temperature (30 ° C) and visually inspected. Full dissolution occurred at the time when no residue was observed.

In the context of the present invention, the formation of the hollow body preferably takes place in a temperature range between incipient softening and thermal decomposition, preferably in the melt region, of the polymeric thermoplastic.

In a further preferred embodiment, the preform, the hollow body and / or the preferably liquid-tight closed hollow body of one or more component (s) comprising one or more materials based on one or different water-soluble polymeric thermoplastics.

In a preferred embodiment, the, preferably blow-molded, hollow body with and without compartments "umkrempeln", d. H. it can be poked through in such a way that the original inner side becomes the outer side and vice versa. This flexibility leads to the resistance to leaks under compressive stress, to avoid stress cracking or breakage, which is particularly high compared to rigid shaped bodies.

The hollow bodies produced according to the invention dissolve completely or substantially in water, in which way the agents contained in the closed hollow body and / or in the compartments are released into the environment. For example, the hollow bodies containing agents according to the method of the invention can be used in an aqueous mechanical washing, cleaning or care process. Preference is given to the use of the hollow body according to the invention in commercial washing machines or dishwashers. A use of the hollow body according to the invention in hand basins or in a bowl is also possible. Important for the release of the agent contained in the hollow body / compartments is a surrounding from the outside aqueous environment.

Flexible hollow bodies in the sense of this invention preferably also include elastic hollow bodies.

The term "elastic hollow body" is understood to mean, in particular, that the hollow bodies containing the agents, in particular detergents, cleaning agents and / or care products have an intrinsic dimensional stability which enables them, under customary conditions of manufacture, storage, transport and handling by the consumer to have a non-collapsing structure which is stable against breakage and / or pressure, wherein the unfilled and / or filled with at least one agent, preferably glycerine, preferably blow-molded hollow body at stretching along its longest axis, a yield stress of between ≥ 3 N. / mm ² and ≤ 15 N / mm ² , and / or at an upsetting distance of 22 mm vertically, centrally, in the direction of its shortest axis a deformation work of between ≥ 0.05 Nm and ≤ 5 Nm occurs, and / or at one Force F ₁ > 0.1 and ≤ 500 N along a path s _{1 is} deformable and after elimination of the force in the direction of original form returns, or after elimination of the force of the original form completely or almost completely assumes, and / or after elimination of a deformation force action a return velocity v of between> 0.01 mm / min and ≤ 650 mm / min has, and / or the elastic modulus the hollow body wall of the preferably unfolded by blow molding flexible unfilled or with means, preferably glycerol, to ≥ 80 vol .-%, filled hollow body ≤ 1 GNm ² , preferably ≤ 0.1 GNm ² , preferably ≤ 0.01 GNm ² , and / or in the case of a hollow, preferably blow-molded, body filled with agent, preferably glycerol, to ≥80% by volume, a compression resistance F _max of between ≥20 N and ≤2000 N occurs.

It is according to the invention without influence, whether this structural stability from the resulting due to various parameters mentioned below properties of the flexible, preferably elastic, hollow body alone and / or from the presence of compartmentalization facilities and / or from the filling with washing active, cleaning active and / or care-active preparations results. In preferred embodiments of the invention, even the flexible, preferably elastic, hollow body itself have a sufficient intrinsic dimensional stability, since this is advantageous to the mobility in machines in the manufacture of the hollow body and the filling during the preparation of detergents, cleaning or care products -Portions affects.

The unfilled hollow bodies with and without compartments of the portioned agents according to the invention can preferably be reversibly deformed by the action of force, at least partially reversibly, and after the elimination of the force, they have a certain return speed. High resetting speeds (for example> 2000 mm / min) are achieved by rigid bodies which "spring back" to their original shape, provided that they do not remain in the pressed-in state. This behavior of "spring back" is undesirable, since in this way stress cracks can occur in the hollow body with and without compartments that allow product leakage. On the one hand, it is therefore necessary to ensure a low return speed of the hollow bodies with and without compartments, on the other hand the hollow bodies with and without compartments should be able to be deformed without breaking or cracking.

As mentioned above, the sheaths according to the invention should preferably be able to be deformed at least partially reversibly (in the case of irreversible deformation, no return speed would be measurable). In preferred embodiments of the present invention, the deformation is completely reversible, i. H. Advantageously, portioned detergents, dishwashing detergents or cleaning compositions according to the invention are preferred in which the unfilled casing returns to its original shape after elimination of the action of force.

The force F ₁ is dependent on the indentation depth, since the hollow body, with and without compartments, offers increasing resistance to the penetrating body. First, it is only important for the present invention that at a force of 500 N or less, the hollow bodies can be deformed with and without compartments at all. In preferred embodiments of the present invention, the data refer to forces at penetration depths of a round rod with 8 mm diameter, in particular at a penetration depth equal to 1 mm, further at 10 mm penetration depth, preferably at 15 mm penetration depth, preferably at 20 mm penetration depth and more preferably at 22 mm penetration depth.

If the distance s _{1 is} defined, not only the force, but also the deformation work can be determined exactly. With a force acting through a round rod with 8 mm diameter and a penetration depth of S ₁ = 22 mm, the deformation work in the case of the preferably blow-molded flexible, unfilled hollow body is well below the values of comparable rigid unfilled bodies, where a deformation work of at least> 5 Nm must be made.

As mentioned above, the hollow bodies with and without compartments should be able to be deformed at least partially reversibly (in the case of irreversible deformation, no return speed would be measurable). In preferred embodiments of the present invention, the deformation is completely reversible, i. H. Advantageously, portioned agents according to the invention are preferred in which the unfilled hollow body with and without compartments returns to its original shape after elimination of the action of force.

In an embodiment which is suitable according to the invention, the hollow body which is preferably blow-molded, filled with glycerol and filled to ≥80% by volume, is characterized by a force F ₁ ≤ 500 N along a path s ₁ = 22 mm, in particular by a force F ₁ ≤ 100 N along a path s ₁ = 22 mm, preferably by a force F ₁ ≤ 60 N along a path s ₁ = 22 mm, preferably by a force F ₁ ≤ 40 N along a path s ₁ = 22 mm and more preferably by a force F ₁ ≦ 20 N along a path s ₁ = 22 mm, perpendicular, in the middle, in the direction of the shortest axis of the hollow body, deformable.

The test of the hollow bodies filled with agent, with and without compartments, unless otherwise stated, was carried out at temperatures of 20 ° C, wherein the hollow body was filled with and without compartments, for example to ≥ 80 vol .-%, preferably with glycerol as the test medium.

It is advantageous if the preferably blow-molded flexible, unfilled or filled with glycerol to ≥ 80 vol .-% hollow body after elimination of the force a recovery speed v ≤ 1000 mm / min, in particular v ≤ 500 mm / min, preferably v ≤ 100 mm / min, preferably v ≤ 50 mm / min, more preferably v ≤ 10 mm / min, and particularly preferably v ≤ 1 mm / min.

The deformation work required to deform the flexible, unfilled hollow body, preferably by blow molding, should be w ≦ 1.0 Nm along a path s ₁ = 22 mm, preferably w ≦ 0.75 Nm along a path s ₁ = 22 mm and preferably w ≦ 0 , 50 Nm along a path s ₁ = 22 mm. To determine the deformation work, the deformation force w acts vertically, centrally, in the direction of the shortest axis of the hollow body.

The deformation work required for the deformation of the flexible hollow body, which is preferably produced by blow-molding and which contains ≥ 80% by volume of glycerol, should be ≤ 5.0 Nm along a path s ₁ = 22 mm, preferably w ≤ 2.5 Nm along a path s ₁ = 22 mm, preferably w ≦ 1 Nm along a path s ₁ = 22 mm, more preferably w ≦ 0.75 Nm along a path s ₁ = 22 mm and in particular w ≦ 0.5 Nm along a path s ₁ = 22 mm, amount. To determine the deformation work, the deformation force w acts vertically, centrally, in the direction of the shortest axis of the hollow body.

Another size for characterizing portioned agents is the crush resistance. This can be determined in the form of a force-displacement diagram with commercially available tablet testers. For the purposes of the present invention, a Zwick type 1425 universal testing machine was used.

The determination of compression resistance is carried out according to DIN 55526 Part 1, characterized in that hollow body with and without compartments (= container) is placed upright between the plates of a pressure tester and compressed, the pressure force and the Plattenweg are recorded until the required compression resistance and Plattenweg be reached or failure occurs by critical deformation or leaking of the container.

The printing press was set to a compression speed of 10 mm / min. Afterwards the test procedure was started. The force applied to the portion at a penetration of 22 mm [N] was printed on the connected printer. The crush strength is given in N. Here, according to the invention, portioned agent-containing hollow bodies with and without compartments are preferred, wherein the compression resistance F _{max of} the portioned agent-containing hollow body (= the filled hollow body with and without compartments) 20 to 2000 N, preferably 50 to 1000 N, particularly preferably 75 to 600 N. , more preferably 100 to 500 N and in particular 150 to 400 N. For testing purposes, the hollow body, preferably produced by blow molding, with and without compartment, is filled to ≥80% by volume with agent, preferably glycerol.

The compression resistance of the flexible, filled or ≥ 80 vol .-% filled with glycerol hollow body preferably produced by blow molding should be between 75 to 400 N, preferably from 100 to 300 N and in particular from 150 to 250 N.

The modulus of elasticity of the hollow body wall of the flexible, unfilled hollow body produced by blow-molding or filled with glycerol to ≥80% by weight should be ≤ 1 GNm ² , preferably ≤ 0.1 GNm ² , preferably ≤ 0.01 GNm ² .

According to the invention is preferred if the flexible, water-soluble, hollow body is formed in one piece or several pieces.

The internal volume of the hollow body and / or the compartments preferably produced by blow-molding can be, for example, between 0.5 ml and 2000 ml, preferably between 2 ml and 500 ml, preferably between 5 and 250 ml, more preferably between 10 and 100 ml, more preferably between 20 and 75 ml, and most preferably between 40 and 50 ml.

The hollow body preferably produced by blow molding according to the invention and / or its compartment (e) is particularly preferably transparent and / or translucent.

Further preferred embodiments contain detergent, cleaning agent and / or care agent portions, wherein the portions contained in the hollow bodies or compartments by a - preferably controllable - water solubility of the hollow body material at a particular time of washing, cleaning or care operation or upon reaching a certain pH or a certain ionic strength of the wash liquor or due to other controllable events or conditions in the aqueous liquor can be fed. The quality of the material as well as its quantity / strength directly influence these solubility properties. Particular preference is given to materials for the hollow bodies, which-based on a certain wall thickness, which determines the stability-dissolve at certain temperatures, pH values, ionic strengths, or after a certain residence time in the aqueous liquor. In this case, such a release process can capture the hollow body as a whole or only a part thereof, so that parts of the hollow body solve when setting a certain parameter combination, while other parts are not yet (but later) or not at all. The latter can be achieved by different quality of the material as well as by different amounts of material (thickness of the wall) or different geometries of the hollow body. For example, it is possible to impede the access of water by the hollow body geometry and thus delay the dissolution process. In another preferred embodiment, it is possible to make walls of the hollow body of different thicknesses (nevertheless of the same material) and thus to allow earlier dissolution at the thinner locations. In likewise preferred embodiments, the walls of the hollow body can be made of materials of different water solubility, for example of polyvinyl alcohols (PVAL) with different residual acetate content. This leads to the formation of perforated walls, which allow water to penetrate into the hollow body and / or escape of the dissolved or undissolved ingredients from the hollow body.

Furthermore, it is possible that the materials of the walls of the flexible, preferably elastic, hollow bodies consist of a washing-active, cleaning-active or care-active active substance, for which PVAL is an example as a builder, or contain such. In the latter case, for example, washing active, cleaning active or care active ingredients that are present only in small amounts in the preparations and their uniform incorporation is therefore not unproblematic, in the material of the wall of the hollow body or in a part of the material of the wall of the hollow body, for example one which dissolves at the stage of washing, cleaning and / or care, in which just the active ingredient is needed, incorporated and released when dissolving the material of the wall at the right time in the fleet. An example of this may be fragrances which are desired in the final stage of the washing, cleaning and / or caring process, but also optical brighteners, UV protectants, dyes and other detergent-active, cleansing or care-active preparations. The basic principle of incorporation of such (usually incorporated in small amounts) components in the materials that form the enclosure of the detergent, detergent and / or care agent portions is the co-pending patent application 199 29 098.9 of the Applicant entitled "active ingredient -Portionspackung ", the disclosure of which is incorporated by reference in its entirety in the disclosure of the present application.

In a particular embodiment of the invention, it is also possible that the walls of the flexible, preferably elastic, hollow bodies containing the detergent, cleaning agent or care agent portions, consist of different materials, so have a heterogeneous structure. For example, in a polymer material forming the wall of the hollow body, islands could be dispersed from a foreign material insoluble in the polymer, for example from another polymer (having different water solubility) or even from a completely different substance (for example, an inorganic or organic substance). Examples of these are water-soluble salts such as sodium sulfate, sodium chloride, sodium carbonate, calcium carbonate, etc .; organic acids such as citric acid, tartaric acid, adipic acid, phthalic acid, etc .; Sugars such as maltoses, dextrose, sorbitol, etc .; zeolites; silicates; crosslinked, for example weakly crosslinked polymers such as polyacrylates, cellulose esters, cellulose ethers such as carboxymethylcellulose. Such a structure may be associated in particularly preferred embodiments of the invention with the advantage that the other substance dissolves faster in water than the polymer, which allows penetration of water into the hollow body and thereby accelerated release of washing active, nurturing or cleaning active components of the Portion contributes. Overall, the entire dimensionally stable hollow body is dissolved faster in such a packaging than a molded body made of a pure polymer material. Similarly, it is possible to form the walls of the hollow bodies of layers of two or more polymers, which can be selected in particularly preferred embodiments so that they complement each other optimally in terms of their properties (stability, heat resistance, water solubility, gas barrier properties, etc.).

In the context of the present invention, blow molding processes for producing filled, liquid-tightly sealed hollow bodies have proven to be particularly suitable. Blow molding methods suitable for the present invention include extrusion blow molding, coextrusion blow molding, injection stretch blow molding and dipping blowing. In addition to a simple, quick and safe manufacturability, the blow-molded hollow body additionally have the advantage that the hollow body produced by the process according to the invention have additionally undergone a stretching step of the preform in addition to the stretching conditions occurring due to the formation of the hollow body. This additional stretching of the thermoplastically processable material causes an additional increase in the shrinkability of the water-soluble material. In a preferred embodiment of the present invention, the hollow bodies produced according to the invention are exposed to shrink-inducing conditions, as described in the copending application German patent application under the file number 102 44 803.5-41 are disclosed and incorporated in full in this application.

The shrinkable for example by increased humidity hollow body not only show a preferred bulging aesthetically pleasing appearance, but are also superior in terms of their tear strength and elasticity not shrunk hollow bodies.

A separate Temperierkreislauf for an optionally present head jaw has proved to be advantageous because the heat sealing of the hollow body by means of a head jaw usually requires higher temperatures than in the remaining part of the mold. If the seal is carried out by means of a head jaw, which is geometrically connected to the molding tool, excessive cooling of the head jaw can lead to leaky or defective seals. A separate temperature control circuit, which provides the temperature required for the heat-sealing is therefore preferred in the context of the present invention.

The wall thicknesses of the hollow body can be produced in different ways by blow molding, by varying the wall thicknesses of the preform, preferably along its vertical axis, according to different thickness, preferably by regulating the amount of thermoplastic material, preferably by means of an adjusting spindle during application of the preform from the extruder die, formed.

The hollow body may be blow molded with regions of different outer circumference and uniform wall thickness by varying the wall thicknesses of the preform, preferably along its vertical axis, preferably by regulating the amount of thermoplastic material by means of an adjusting spindle during application of the preform from the extruder die. formed.

In this way, different geometrical configurations of the hollow body can be blown with and without compartments. In a single cycle, bottles, balls, Santa Claus, Easter bunnies or other figures can be blown, which can be filled with medium, then sealed and then demoulded.

It is particularly advantageous that the hollow body can emboss and / or decorate during blow molding in the blow mold. By appropriate design of the blow mold, a motive can be mirror-inverted transferred to the hollow body. In this way, the surface of the hollow body can be designed practically arbitrary. For example, information such as calibration marks, application instructions, danger symbols, brands, weight, filling quantity, expiration date, images, etc. can be applied to the hollow body.

In a preferred embodiment, the preform, the hollow body and / or the liquid-tight closed hollow body of one or more component (s), wherein the component comprises one or more materials based on one or different water-soluble polymeric thermoplastics.

The preform, the hollow body and / or the liquid-tight closed hollow body may be tubular, spherical or bubble-shaped. A spherical hollow body preferably has a shape factor of> 0.8, preferably of> 0.82, preferably> 0.85, more preferably> 0.9 and particularly preferably of> 0.95.

The shape factor in the sense of the present invention can be precisely determined by modern particle-measuring techniques with digital image processing. A common method is, for example, the Camsizer ^® system from Retsch Technology or KeSizer ^® of the company Kemira. These methods are based on that the hollow body or body are irradiated with a light source and the hollow body detected as projection surfaces, digitized and processed by computer technology. The determination of the surface curvature is carried out by an optical measuring method, in which the "shadow cast" of the hollow body to be examined is determined and converted into a corresponding shape factor. The underlying principle for determining the shape factor has been described, for example, by Gordon Rittenhouse in "A visual method of estimating two-dimensional sphericity" in the Journal of Sedimentary Petrology, Vol. 13, No. 2, pages 79-81. The measuring limits of this optical analysis method are 15 μm to 90 mm. Methods for determining the shape factor for larger particles are known to those skilled in the art. These are usually based on the principles of the aforementioned methods.

The release from the hollow bodies with and without compartments can be achieved either at different times that the blow-molded walls have different dissolution or disintegration rates. This is possible, for example, by the choice of material thickness.

The walls of the blow-molded hollow body and / or the compartments have a wall thickness of between 0.05-5 mm, preferably between 0.06-2 mm, preferably between 0.07-1.5 mm, more preferably between 0.08-1.2 mm, more preferably from 0.09-1 mm, and most preferably from 0.1-0.6 mm.

The filling opening of the hollow body after filling can be sealed in a liquid-tight manner, preferably by closing the material, preferably by means of thermal treatment, more preferably by setting up a molten metal.

The filling opening or openings of the hollow body can advantageously be sealed in a liquid-tight manner by thermal treatment, preferably by fusing the walls adjoining the opening, in particular by means of clamping jaws.

The blow-molded hollow body and / or the respective compartments of the water-soluble hollow body can be filled from any direction, for example from above, from the side and / or from below.

In one embodiment of the inventive method, a plurality of hollow bodies can also be formed in a hollow body by blow molding a preform having a plurality of layers, during which a gap is formed between the layers during blow molding so that these layers each form separate hollow bodies or compartments. These separate hollow bodies or compartments can be connected to one another.

In a preferred embodiment, it is possible by coextrusion to produce a preform having a plurality of layers, preferably 2 to 5, which is then blow-molded into a hollow body in which at least one wall of the hollow body and / or in which at least one wall of at least one compartment is formed in multiple layers , Serial, parallel and / or concentric arrangements of hollow bodies and / or compartments, preferably having walls of the same or different materials as described above, may preferably be produced by blow molding, preferably, but not exclusively, by using at least one double and / or multiple and / or coextrusion blown dome. It is preferred if in this case the preforms are based on the same or different thermoplastics.

According to the invention, however, the multipart design of the blow-molded hollow bodies is particularly advantageous. Especially with regard to the dosing of consumers and / or in terms of product aesthetics and / or in view of the solubility and / or release of a coated agent in an aqueous solution and / or an application environment such as a washing or cleaning liquor show up improvements.

Individually packaged in containers made of water-soluble material preparations can be dosed consumer-friendly and represent a marked by particular aesthetics alternative to other single dosage forms, especially tablets. In many areas, this single dose is perceived as comfortable. The consumer takes the appropriate product, doses it and need not worry about the dimension of appropriate quantities. In many cases, this form of supply but also meets the criticism that a situation-dependent modification of the dosage is no longer possible and thus, for example, with one dosing unit too little, but with two units is overdosed. In the offer form of the tablet, the proposal is regularly brought to the manufacturers to design them as chocolate bars, so that the consumer can "break off" his individual dosing units as needed. Compared to powders or liquids on the one hand (complete dosing with almost unlimited variety of dosing) and tablets or so-called pouches on the other side (a Dosiermöglichkeit), there is still the desire for a product segment, for example, with two to twenty separately dosable units allows a situation-based dosage, without having to use an external measuring vessel every time.

In a particularly preferred embodiment of the method according to the invention, the water-soluble, blow-molded hollow bodies are formed in several pieces and have wall thicknesses of 0.05-5 mm in the region of the filled hollow volume.

The inventive method allows the production of filled and sealed containers and is preferably carried out in-line by the "blow-fill-seal" method (BFS technology). In this blow-molding / filling-closure technique, the respective desired shape is first blown, then filled with the contents and then sealed in one operation. In this case, a tube of plasticized water-soluble plastic material is extruded into an open blow mold, the tube is stretched by a jaw under the blow mold, the blow mold is closed and expanded by creating a pressure gradient effective on the tube and applied to the forming wall of the blow mold to form the container ,

According to the invention, the blow-molded hollow bodies are designed in several pieces, ie. H. that in the blow mold a plurality of separate hollow volumes are generated, which are connected to each other via webs. The webs are formed by pressing the two hose walls in the blow mold, where it has no cavities for forming the hollow volumes. The material thickness of the webs can be determined by the wall thickness of the extruded tube and the shape of the pressing tool, the wall thickness of the hollow volumes depends on the amount of polymer material that is available for a given volume of the hollow body to be produced. Depending on the shape of the contiguous hollow volumes to be produced, the wall thickness varies more or less strongly in the area of the hollow volumes. Usually, blow-molded hollow bodies have higher wall thicknesses in the vicinity of the bottom and top regions than in the middle of the container. Thicker wall thicknesses in the floor and head area can not only be the result of the blowing process, but in particular also be targeted by utilizing their thermal heat capacity in order to achieve a better sealability of the hose end pieces with minimized risk of leakage. In particular, when filling with colder content / agent compared to the preform, undesirable premature cooling and solidification of the thermoplastic melt may otherwise occur, resulting in insufficient and non-liquid sealed seal portions. In the case of the multi-part hollow bodies preferred according to the invention, the wall thickness of the hollow bodies can also be slightly higher in the vicinity of the stem than in the areas remote from the stem ("bulged out").

The term "blow-molded hollow body" thus comprises a basic unit of at least two interconnected units ("hollow volumes") within a multi-block blister unit. The individual units or hollow volumes are preferably individually separable. For this purpose, the Multi-block blister units should be provided with suitable crushed seams and / or perforations to allow separation of a serviceable unit from the overall block.

A multiblock blister pack which can preferably be produced according to the invention has the following embodiment: it is formed from a tube which is congruent in its circumference and forms an elongated oval in its cross section, ie normal to the extruded longitudinal axis; these two longitudinal sides in the cross-sectional oval are welded in mirror image to each other and form both adjacent surfaces and non-adjacent, namely the cavities, having areas.

Inventive methods in which the water-soluble, blow-molded hollow body in the region of the filled hollow volume wall thicknesses of 0.06-2 mm, preferably between 0.07-1.5 mm, more preferably between 0.08-1.2 mm, even more preferably between 0.09-1 mm and most preferably between 0.1-0.6 mm are preferred.

The wall thickness of the webs connecting the filled hollow volumes is preferably at most twice the wall thicknesses in the region of the filled hollow volume. In particularly preferred methods, the webs connecting the filled hollow volumes are further thinned in their wall thickness by a preferably centrally extending pinch seam, preferably with an additional perforation line, to predetermined breaking points which are in the range from 5 to 200 .mu.m, preferably 10 to 150 .mu.m, particularly preferably 15 to 100 microns and in particular 20 to 70 microns are. The separability of the individual hollow volumes of the multi-block blister unit ("blow-molded hollow body") can thus be achieved by a sufficiently thin design of the webs or by a perforation of the webs.

Since each hollow volume is filled individually by means of a Fülldorns, it is possible to fill the individual hollow volumes with different compositions. In this way, for example, detergents or cleaning agents can be prepared in multiblock blister form, in which the consumer the present in a void volume agent for an added benefit (for example, additional bleach and / or additional brightener for white laundry, additional color transfer inhibitors for coloreds, additional enzymes for certain contaminants such Blood etc.) or can not use by separating the corresponding hollow volume. This function can be carried out to the extent that each individual hollow volume of a multiblockblister unit is filled differently - however, for reasons of process economy and consumer convenience, it is preferred that the number of different compositions present in a multiblockblister unit be manageable, usually one, two or three compositions. to keep.

It is also possible to fill two differently composed agents in one and the same hollow volume and to separate them within a hollow volume of each other. This embodiment has the advantage that the consumer can not separate the compositions from each other, since he would have to destroy the hollow volume, but still incompatible substances (in the washing or cleaning agents such as bleach and enzymes) can be assembled side by side. The separation into several compartments within a hollow volume succeeds either by correspondingly shaped hollow volumes with a plurality of cavities which can not be separated from one another or by the production of hollow volumes which have partitions.

The latter embodiment is preferred and can be realized simply by extruding a tube of plasticized plastic material and at least one formed from the plastic material, extending continuously inside the tube in an open blow mold, the tube is stretched, the blow mold and closed by expanding a pressure gradient acting on the tube, it widens and is applied to the forming wall of the blow mold to form the container. Hereby, by closing the opened blow mold, the front end of the tube and the front end of each partition are welded together to close the container bottom connected to each partition wall, the expansion of the tube by supplying blown air from the container bottom opposite to the container neck End of the closed blow mold ago so that the blowing air on both sides of each partition wall expands to form separate chambers in the container.

Due to the fact that according to the invention the front ends of the tube and the dividing wall, ie the parts of the plastic material reaching the lower end of the blow mold during extrusion, are welded to form the container bottom, the upper end of the mold cavity is associated with the container neck Further processing of the expanded Container within the closed tuyere be performed by after the expansion of the container by blowing air, which is inserted through the container neck on both sides next to each partition, the filling process for each inner container chamber through the container neck is performed without opening the tuyere or the container refer to.

However, a production variant of compartmented hollow volumes may also be preferred, in which the at least one co-extruded dividing wall itself represents a coextruded, preferably elongated, in cross-section to an oval, preferably concentric tube. This can be blown and filled only on both sides analogous to the blowing and filling process described above, so that again mutatis mutandis by collapse of the central, enclosed volume one, so quasi two-layer, dividing wall results. However, it may also be desired to fill the middle compartment by providing a further blowing and filling mandrel. It is further conceivable to extend this principle to the coextrusion of several bubble-extruded and filled compartments, wherein it may be particularly preferred to different hoses / preforms by a different choice of materials different properties such as a barrier function, a function as a mechanical stability transmitter, a function as a temperature switch shall be included. Furthermore, it may also be desirable to combine the tubes / preforms or partitions co-extruded from different materials into multilayer hoses / preforms d. H. collapse. In this way, one-chambered hollow volumes can be produced, which are covered by multilayer sheaths; Examples which may be mentioned are combinations of polyethylene glycol, preferably on the inside, as sticky, with PVA or recycled polymer, preferably on the inside, with fresh thermoplastic.

The filling process can be carried out both in single-chamber hollow volumes as well as in the multi-chamber hollow volumes by means of a combined blowing and Fülldornes or by a separate Fülldorn which is introduced after retraction of the mandrel from the container neck in this. A particular advantage of the BFS method is then that after striking the container neck of the container by means of a still-closed blow mold additional welding process finished molded and can be hermetically sealed at the same time with a closure formed by the welding process. This can be done by moving upper welding jaws or head jaws, which are arranged at the top of the blow mold. In this case, any desired form and / or closure operations can be carried out, for example, a tear-off at a predetermined breaking point or separation point closure can be formed, preferably in the form of a rotary toggle closure. It is understood that an external thread on the container neck could be formed to form a screw with a separate closure element. In the case of the moldings according to the invention, due to their water-soluble nature of the polymer shell (s), a particularly preferred upper closure form is represented merely by sealing and separating protruding neck material, analogously to the welding of the front end of the tubular or partition wall (s) to the hollow body bottom. The welding operation performed on the neck of the container may provide for separate closures for each chamber of the container or a closure closing all the chambers of the container together.

The formation of a self-subdivided extrusion hose can be achieved, for example, by providing the end of the extruder device facing the blow mold with a nozzle ring in which a nozzle core is arranged coaxially to the nozzle longitudinal axis, whose core tip defines an annular outlet with the end region of the nozzle ring the extruded plastic material emerges in the form of a hose. The molten plastic material passes to the outlet via an annular gap formed between the nozzle ring and the nozzle core. This annular gap narrows at the transition between the core tip and the upstream adjoining part of the nozzle core, so that there is a storage area for the supplied plastic material.

The core tip is bolted to the adjoining, upstream portion of the nozzle core via an externally threaded pin such that the facing surfaces of the core tip and subsequent portion of the nozzle core are spaced apart. The corresponding surface of the core tip forms a funnel surface, while the facing surface of the remainder of the nozzle core defines a conical surface. These surfaces, which preferably include inclination angles of 65 and 60 to the longitudinal axis of the nozzle, form between them a guide device for plastic material branched off from the annular gap, which enters the storage area between the surfaces. By drilling in the external thread having pins of Kernspitre this branched plastic material passes into a formed in the front of the core spit outlet slot. From there, the branched plastic material exits as transverse within the extruded tube web, which forms the partition wall after the expansion of the tube in the thereby formed container. On both sides next to the exit slot, ie on both sides of the The plastic sheet exiting the exit slot, preferably in the end face of the core tip each have an outlet opening for supporting air, which are connected via branch lines, which are formed in the pin having the male thread, with a central air channel.

The air supplied from the air duct via the outlet openings is provided as supporting air, which only prevents the collapse of the extruded tube and its sticking to the partition wall forming the web. The widening of the container in the blow mold is carried out in an additional step by means of a blowing and Fülldornes, which has in an analogous arrangement to the outlet openings of the core tip blowing openings for the supply of expanding blown air. These blowing openings can then also serve as filling openings for the supply of the filling material to the container chambers.

As mentioned above, the shape of the container neck of the container produced by the process according to the invention is carried out by means of upper movable welding jaws on the relevant blow mold. By the upper welding jaws any closure training may be in the way during the shaping of the container neck, as is well known in the art for example according to the Einkammerbehältern bottelpack ^® system of the company Rommelag. For example, a rotary toggle closure can be formed on the neck of the container. Here, the welding operation is carried out so that both chambers are closed by a twisting knob, which is separable at a separating point designed as a predetermined breaking point by being rotated by means of its molded-on handle.

After retraction of the mandrel and insertion of a Fülldornes, each having a filling opening for each separated by the partition container chamber, both chambers can now be filled while the container is still within the blow mold.

After filling, the Fülldorn is withdrawn, and the upper welding jaws are moved together to perform on the container neck another welding process in which the container neck is finally formed and simultaneously closed.

After filling the container and retracting the filling mandrel, inserts may be inserted into the container neck, if desired, prior to hermetically sealing the container. It may be further active substance in solid form (for example an enzyme tablet) or non-functional "gimmicks" or other foreign part, which can be inserted by means of vacuum gripper before the welding jaws are moved together to weld the insert and at the same time a hermetic seal to build.

The inventive method is not limited in terms of the size of the multiblock blister pack and the individual hollow volume. Preferred processes according to the invention are characterized in that the filling volume of a filled hollow body is 1 to 1000 ml, preferably 2 to 500 ml, particularly preferably 5 to 250 ml, more preferably 10 to 100 ml and in particular 15 to 50 ml.

Also with regard to the number of hollow volumes to be combined into a multiblock blister pack, the method according to the invention is not limited. Preference is given here to processes in which a filled container is formed from a series of 2 to 100, preferably from 2 to 50, particularly preferably from 3 to 20 and in particular from 4 to 12, filled hollow volumes connected to one another via webs.

The release of the hollow bodies produced in the process according to the invention is carried out by disintegration or dissolution of the container wall under conditions of use. It must not be necessary that the entire container dissolves before release occurs. A faster release according to the invention can be effected in that the container wall is provided with special "predetermined breaking points" which quickly disintegrate or dissolve under conditions of use and thus lead to an early release of the ingredients. Here, inventive methods are preferred in which the water-soluble, blow-molded hollow body in the region of the filled hollow volume have a region of lesser wall thickness, which is preferably mechanically protected by recess. The areas of lesser wall thickness in this case are 0.1 to 0.9 times, preferably 0.2 to 0.85 times, particularly preferably 0.3 to 0.8 times and in particular 0.5 - Up to 0.75 times the wall thickness of the hollow volumes.

The shape of the container, ie both the Multiblockblisters and the individual hollow volume can be chosen arbitrarily. Preferred methods are characterized in that the filled hollow volumes are rotationally symmetrical to their longest axis and preferably to the normal formed on the Quetschfläche. This preferred shape preferably has a length for the individual hollow volume: Diameter ratio of 1.5: 1 to 50: 1, with ratios of 4: 1 to 10: 1 are preferred. The connecting webs are preferably arranged along the long hollow-volume sides in such forms.

It may also be preferred according to the invention that the filled hollow volumes to the normal to the squish surface are not rotationally symmetrical. This can be achieved, for example, by the choice of a blow mold whose depth is more than 0.5 times the pitch width. When the extruded tube is now blown between two such molds, a hollow volume is created which has a width (expansion in the direction of the squish surface, perpendicular to the extrusion direction of the original tube) corresponding to the pitch width of the blow mold but a depth (extension in the direction of the normal on the squish surface and perpendicular to the extrusion direction of the original tube), which is a multiple of the pitch width. Such ovalized hollow bodies may be preferred, wherein in particular width: depth ratios of 1: 1.1 to 1: 3, preferably from 1: 1.2 to 1: 2.5 and in particular from 1: 1.3 to 1: 2 , are preferred.

Preferred processes are also characterized in that the filled hollow volumes have a length (along the extrusion direction of the original tube) of from 30 to 120 mm, preferably from 40 to 100 mm and in particular from 45 to 70 mm.

Between the individual connecting webs, the filled hollow volumes in preferred processes have a width (in the direction of the squish surface, perpendicular to the extrusion direction of the original tube) of 10 to 70 mm, preferably 15 to 60 mm and in particular 20 to 40 mm.

To achieve bulging, aesthetically appealing-looking portions, it has proved to be particularly advantageous in the context of the present invention, when a cooled gas is added to the hollow body in the course of the inventive method before the, preferably liquid-tight, closing of the hollow body. Gases in the context of the present invention are all substances which have a boiling point below 25 ° C. at an air pressure of 1 bar. When added to the hollow body, the cooled gas advantageously has a temperature below 20 ° C., preferably below 10 ° C., more preferably below 0 ° C., in particular below -10 ° C., particularly preferably below -20 ° C. , advantageously below -60 ° C, for example -70 ° C, -78 ° C, -100 ° C or about -190 ° C.

The advantage of cooled gases lies in their occurring during heating and constant pressure strong increase in volume, resulting in a "pumping" of the filled hollow body. This volume expansion is particularly drastic when the gaseous substances at 25 ° C. are added to the hollow bodies as solids or liquids, which is particularly preferred in the context of the invention. Due to the ease of handling and the economically easy access liquefied gases such as liquid nitrogen, butane, propane, argon have proven. However, the use of solid carbon dioxide, which is also known as dry ice, has proven to be particularly advantageous. It can be easily dosed in the form of pellets with the other ingredients in the molded hollow body or can also be introduced into the hollow body after filling, followed by the liquid-tight closing of the hollow body as a subsequent step. By warming the gases to room temperature, these expand and form plump, elastic, liquid-tight sealed hollow body.

The enveloping material of water-soluble thermoplastics surrounding the filled hollow body advantageously forms a barrier layer for the gases to be used. In the context of this invention, the listed polyvinyl alcohols have proven particularly suitable, which has an excellent barrier layer for a large number of gases, in particular for carbon dioxide.

Particularly advantageous is the use of gases that can be easily detected so-called test gases. The escape of these gases from the filled hollow body is, due to the build-up of internal pressure during heating, is particularly fast detectable if there is a defect in Hülkörpermaterial. The detection can be done for example in a vacuum chamber in the additional gas-specific sensors are mounted. For leak detection, the closed and filled hollow bodies may be passed, for example, through a tunnel with a slight vacuum, where highly sensitive detectors indicate traces of the indicator gas. Depending on the detector, in principle, all gases or gas mixtures are available as test gases, but preferably the gases selected from the group noble gases such as helium, neon, xenon or argon, and nitrogen, carbon dioxide, carbon monoxide, gaseous hydrocarbons such as butane, propane, ethane , Methane, fluorocarbons, as well as any mixtures of the aforementioned gases. Particularly preferred are mixtures of carbon dioxide with carbon monoxide and / or hydrogen and / or noble gases. Also preferred are gas mixtures of nitrogen with hydrogen, preferably with a molar mixing ratio of nitrogen: hydrogen greater than 1: 1, preferably greater than 5: 1, more preferably greater than 8: 1 and in particular 95: 5. Hydrogen-containing test gas mixtures are preferred according to the invention because of their excellent detectability. Hydrogen-containing test gas detectors are sold, for example, by the company Sensitor Technologies, Mühlheim, Germany under the name H 2000.

In a further preferred embodiment of the method according to the invention, following the liquid-tight closure of the preferably blow-molded hollow body, an additional detection step for leaks follows. In particular, in the industrial application of the method according to the invention with a high product throughput, it is advantageous to check the filled blow-molded hollow body directly after its production for leaks to the contamination of other filled hollow bodies, optionally in the same outer packaging as the damaged filled hollow body to avoid and ensure quality assurance. Although a purely visual assessment of the hollow body produced is possible in principle, but offers little economic benefits, especially in industrial production with high product throughput, as very labor-intensive. Electronic detection systems for leaks have proven to be particularly advantageous. A particularly suitable detection system for the determination of leaks in, in particular with liquids, filled preferably blow molded hollow bodies is the high voltage leak detector (HVLD detector) marketed by the company Rommelag. The detection method is based on the electrical conductivity of the filling material, which is enveloped by a non-conductive or only slightly conductive polymer. If there is a leak, the discharge current flows through the leakage opening into the hollow body and the detection of this current leads to the ejection of the damaged, filled hollow body. Suitable detectors are, for example, the HVLD 923 and HVLD 924 ex Rommelag.

In a preferred embodiment, in particular by means of blow molding, at least one hollow body region and / or compartment region with at least one outer surface of between 0.01 mm ² and 10 cm ² can be produced, the wall thickness of this surface increasing faster in an aqueous solution to ensure it is less than the wall thickness of the adjacent area. Without being limited to specific wall thicknesses, the wall thicknesses of these outer surface areas are preferably below 80 μm, more preferably below 60 μm, even more preferably below 50 μm, particularly preferably in the range from 10 to 30 μm.

Advantageously, the regions of lesser wall thickness are produced by impressing information such as calibration marks, application instructions, danger symbols, marks, weight, filling quantity, expiration date, images, particularly preferably by imprinting a logo.

The wall thickness of the hollow body and / or the compartments, which is preferably formed by blow molding, should be designed so that the agent contained in the hollow body and / or in the compartments, in particular detergents and / or cleaning agents, within the aqueous application liquor within ≦ 5 min, preferably within ≦ 3 min, preferably within ≦ 1 min, partially or completely liberated.

To determine the release time, the hollow bodies with and without compartment in 10 liters of agitated water, stirrer speed ≥ 60 U / min, with the water at 90 ° C, preferably at 60 ° C, more preferably at 40 ° C, even more preferred is heated to 30 ° C and particularly preferably to 20 ° C. More preferably, the release time is determined directly in the aqueous application liquor of at least one commercially available washing and / or dishwashing machine.

The water-soluble thermoplastic used in formation, preferably by blow molding, of the hollow body and / or the compartments is preferably selected from the group comprising polyvinyl alcohol (PVA), acetalized polyvinyl alcohol, polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose, starch and derivatives of the abovementioned substances, in particular derivatives the polyvinyl alcohol (PVA), acetalated polyvinyl alcohol, cellulose and / or mixtures of the aforementioned polymers, wherein polyvinyl alcohol and partially hydrolyzed polyvinyl acetate is particularly preferred.

The polyvinyl alcohols described above are commercially available, for example under the trade name Mowiol ^® ex Clariant (risen in the Kuraray Specialties Europe KSE).

The water-soluble thermoplastic used in the formation, preferably by blow-molding, of the hollow body and / or the compartments can additionally comprise polymers selected from the group comprising acrylic acid-containing polymers, polyacrylamides, oxazoline polymers, polystyrene sulfonates, polyurethanes, polyesters, polyethers and / or mixtures the above polymers.

It is preferred if the water-soluble thermoplastic used to form the hollow body and / or the compartments comprises a polyvinyl acetate whose degree of hydrolysis is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%.

More preferably, the water-soluble thermoplastic used to form, preferably by blow-molding, the hollow body and / or the compartments comprises a polyvinyl alcohol whose average molecular weight is in the range of 10,000 to 100,000 gmol ^-1 , preferably 11,000 to 90,000 gmol ^-1 preferably from 12,000 to 80,000 gmol ^-1 and in particular from 13,000 to 70,000 gmol ^-1 .

Preferred in the context of the present invention are polyvinyl alcohols which have a narrow molecular weight distribution, particularly preferably with a distribution ratio of d10: d50> 0.66.

In a further embodiment, the material used to form the hollow body comprises the water-soluble polymeric thermoplastics in amounts of at least 50% by weight, preferably at least 70% by weight, more preferably at least 80% by weight and in particular at least 90 Wt .-%, each based on the weight of the entire hollow body material.

To facilitate their preparation, in particular with regard to their production by blow molding, the hollow body plasticizing aids, ie plasticizers may contain. This may be advantageous in particular when polyvinyl alcohol or partially hydrolyzed polyvinyl acetate has been selected as the material for the hollow bodies. Glycerol, triethanolamine, ethylene glycol, propylene glycol, diethylene or dipropylene glycol, diethanolamine and methyldiethylamine have proved particularly suitable as plasticizing auxiliaries. However, depending on the amount and type of plasticizers, the surfaces of the processed water-soluble polymeric thermoplastics can provide the consumer with a haptic impression of "stickiness". Due to their excellent softening effect and the reduced tackiness of the surfaces of the hollow body according to the invention, the water-soluble, polymeric thermoplastics in a particularly preferred embodiment as plasticizers mono-, di- or triglycerides, preferably mono-, di- or triglycerides, at least with a C ₆ -C ₃₀ fatty acid residue are linked, more preferably those which are linked at least to a C ₁₂ -C ₂₄ fatty acid residue, in particular glycerol monostearate or glycerol monooleate.

It is advantageous if the water-soluble polymeric thermoplastic plasticizer in amounts of at least> 0 wt .-%, preferably of at least> 1 wt .-%, more preferably of ≥ 10 wt .-%, especially preferably of ≥ 20 wt .-% and in particular of ≥ 30 wt .-%, each based on the weight of the entire hollow body material contains.

The flexible, preferably elastic, water-soluble hollow body may have flange parts and optionally connected by positive engagement and / or material closure, preferably by welding with at least one other mold and / or closed.

It is preferred if, in particular in the case of the hollow bodies produced by the blow molding process, at least one wall of the hollow body and / or at least one wall of at least one compartment is formed in a multi-layered manner.

It is also preferred if at least two layers of the wall of the hollow body and / or at least two layers of at least one compartment are configured, in particular in the case of the hollow bodies produced by the blow molding process, so that a gap is formed between the layers.

In a particularly preferred embodiment, a detergent, cleaner and / or care product portion prepared according to the invention comprises a flexible, preferably elastic, hollow body of at least one washing-active, cleaning-active or care-active preparation wholly or partly surrounding casing from a washing, cleaning, or maintenance conditions of disintegratable, preferably blow-molded, material having at least one compartment, the compartment (s) containing / containing one or more detergent-active, cleaning-active or care-active preparation (s).

In the mentioned embodiment, the one hollow body comprises at least one compartment, ie a chamber, in its interior. Such a chamber or such a compartment is usually limited by walls (in only one compartment, these are the walls of the hollow body) limited space. Within the walls of the flexible, preferably elastic, hollow body according to the invention, however, several rooms may be located. These can be formed either by separating individual spaces from one another by walls which in the context of the present invention are referred to as "compartmentalizing devices" and spatially separating the same or different washing-active, care-active and / or cleaning-active components or preparations, or that various washing-active, care-active or cleaning-active components or compositions are directly adjacent to one another but do not mix with one another. In such a case, the interfaces (phase interfaces) of the contiguous components or compositions are virtually the compartmentation devices. The chamber or the compartment is completely or partially, advantageously completely, surrounded by the enclosure of a disintegratable under washing, cleaning and / or care conditions, preferably blow-molded, material that forms the wall of the flexible, preferably elastic, hollow body. In the compartment or in the chamber, one or more detergent-active, cleaning-active or care-active preparation (s) is / are contained. in most embodiments of the invention, one compartment advantageously contains several detergent-active, cleaning-active or care-active preparations; However, the case of the presence of only one such preparation in a compartment or in a chamber is also conceivable.

In a particularly preferred embodiment, the hollow body produced according to the invention contains in its interior a plurality of compartments or chambers each containing one or more detergent-active, cleaning-active or care-active preparation (s). Examples of these are cuboidal or trochoidal, in particular spherical, flexible, preferably elastic, hollow bodies which have two, three or four or even more compartments, each containing one or more detergent-active, cleaning-active or care-active preparation (s). A major advantage of this embodiment is that the various detergent-active, cleaning-active or care-active preparations can be distributed to the compartments as best for the specific requirements. Thus, components that adversely affect each other in their effectiveness (for example, enzymes, alkali, bleach, etc.) or otherwise - for example, due to the state of aggregation - would mix together, for example, solid and liquid components, are spatially separated. On the other hand, it is possible to spatially separate components which should optimally be released into the respective liquor at different times of the washing, cleaning or care process and to introduce them into the liquor at the optimum time.

The size and shape of the individual compartments within a flexible, preferably elastic, hollow body is not critical and can be largely tailored to the needs of the individual case. Thus, for certain detergent-active, cleaning-active or care-active preparations or mixtures thereof, which are present in larger quantities, larger compartments are provided than for preparations which are present only in small quantities. In other embodiments of the invention which can be used with advantage, mixtures of certain preparations, which are provided at the beginning of the washing, cleaning or care run and are present in specific amounts, can be spatially separated from other components or components required in other quantities and arranged in compartments of a different size become.

In a particularly preferred embodiment of a flexible, preferably elastic, hollow body having at least one, preferably a plurality of compartment (s) containing the detergent, cleaning agent or care product portion, two or more, one or more washing-active, cleaning-active or care-active preparation ( En) contains compartments of the hollow body, which are arranged enclosing each other. The compartments with the detergent-active, cleaning-active and / or care-active preparation (s) are thus not arranged side by side or above / below each other in the hollow body, but enclosing each other, for example more or less concentric ("onion model") or more or less coaxial ("Multi-layered rod model") or such that the innermost compartment is completely surrounded by the next outer one, possibly completely again from the following, etc. In such a case, the detergent-active, cleaning-active or care-active substances can be distributed among the compartments be that the first components needed in the washing, cleaning or care process are contained in the outermost compartment which is first exposed to water or liquor while (a) later required component (s) in ( a) further compartment (s) is / are arranged and is protected from the ingress of water by the more external compartments. In the context of this embodiment, it is not necessary that the inner compartments are completely enclosed by the outer; a partial enclosure is also within the scope of the present invention.

A further preferred embodiment relates to at least one flexible, preferably elastic, hollow body containing a detergent, cleaning agent and / or care agent portion, the wall of the hollow body and / or the compartments comprising at least one wash-active, cleaning-active and / or care-active preparation which is disintegratable under washing, cleaning or care conditions. It is preferred if the material used to produce the hollow body and / or the compartments and / or the preform comprising at least one water-soluble thermoplastic already comprises a washing-active, cleaning-active and / or care-active preparation, which is subject to washing, cleaning and / or care conditions is disintegratable.

The size, shape and arrangements of the compartment (s) and the at least one detergent-active, cleaning-active or care-active preparation may be designed in the same way as in the embodiments described above, ie. H. it can be arranged in a flexible, preferably elastic, hollow body one or more compartments of any shape and size, each with one or more washing active, cleaning active or care-active preparation (s). In the present case, however, several such flexible, preferably elastic, hollow body are present together.

In this case, it corresponds to a preferred embodiment, when the two or more flexible, preferably elastic, hollow body made of several different materials or (possibly similar) materials with different properties, which - are disintegrated under washing, cleaning or care conditions - with particular advantage. Such hollow body materials include, but are not limited to, one or more water-soluble polymer (s), preferably one or more of polyvinyl alcohol (PVAL) (optionally acetalized), polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose, and their derivatives and mixtures thereof, more preferably (optionally acetalated) polyvinyl alcohol (PVAL).

In a further, likewise preferred embodiment, it is advantageous in accordance with the invention if the flexible element (s), preferably elastic (s), hollow body comprises one or more materials from the group of acrylic acid-containing polymers, polyacrylamides, oxazoline polymers, polystyrenesulfonates, polyurethanes , Polyesters and polyethers and mixtures thereof.

In a further preferred embodiment of the invention, the two or more flexible, preferably elastic, hollow body may consist of two or more different materials, which may be selected for example from the materials listed above, but may also comprise other materials. With particular advantage, in the case of the presence of a plurality of flexible, preferably elastic, hollow bodies, the walls (= walls) of these hollow bodies may consist of two or more similar materials, for example materials of the same monomer building blocks, but materials with different properties. Examples include similar materials of different molecular weight (and thus different solubility), PVAL materials with different degree of acetalization (and thus different solubility or different solution temperature in water), materials with different amounts of grafted co-monomers o. Ä. Be.

It corresponds to a further preferred embodiment that, in the case in which a plurality of flexible, preferably elastic, hollow bodies are present, these flexible, preferably elastic, hollow bodies have a different geometric shape. This can advantageously lead to different dissolution behavior or different kinetics of the release of the detergent, cleaning agent or care agent portion contained in the compartment (s) of the hollow body.

Further preferred is an embodiment of the detergent, cleaning agent or care agent portions, in which the two or more flexible, preferably elastic, hollow body form a - particularly preferred, but not necessarily releasable - composite. A composite of two or more flexible, preferably elastic, hollow bodies can be used with particular advantage if either detergent, cleaning agent or care agent portions of different composition are to be metered (for example heavy-duty detergent and colored laundry detergent, in the latter, for example, bleaching components not desired or not in the same concentration as in the former, the bleach containing hollow body could then be removed by the user, if colorful laundry should be washed) or if - for small amounts of laundry or dishes - only a partial dose of flexible, preferably elastic, hollow bodies contained detergent or care portion. Particularly preferably, such a composite could be produced by gluing, fusing, welding or clamping the flexible, preferably elastic, hollow bodies; Mechanical clamping also allows easy release of the composite. In particularly preferred embodiments, such composite hollow bodies are again detachable from one another in an aqueous environment, for example by using a water-soluble adhesive; This could ensure that a composite used in the automatic washing, cleaning or care process is completely dissolved and removed from the machine with the washing, cleaning or rinsing liquor.

For the materials that make up the devices for compartmentalizing, the above information on the materials of the flexible, preferably elastic, hollow body apply accordingly. With regard to a reliable and simple method of production, in a preferred embodiment of the invention, the compartmentalizing devices within the flexible, preferably elastic, hollow bodies of the same materials as the hollow body itself. This allows the one-piece production in one process step and makes the manufacturing process particularly economical.

In principle, however, it is also possible to select the materials of the devices for compartmentalizing independently of the materials of the flexible, preferably elastic, hollow bodies. This has the advantage that special requirements in terms of properties, for example in the water solubility, the compartmenting facilities can be taken into account.

In a preferred embodiment, the compartmentation device (s) is one (or more) an activity reduction of at least one component of a detergent-active, cleaning-active or care-active preparation inhibiting device (s). Examples of these are all the cases in which components of washing-active, cleaning-active or care-active preparations are spatially separated taking into account a mutual impairment of their activity. The compartmentalizing devices should then have properties that meet these requirements, for example, be substantially impervious to water vapor to keep bleach free of moisture, or should be acid or alkali free to protect enzymes from premature decomposition. Such inhibition of activity reduction not only directly contributes to a better activity of the particular protected component, but also allows to reduce the amounts of such components, since an excess is no longer required in anticipation of the otherwise usual loss of activity.

In other particularly preferred embodiments, the compartmentation device (s) is / are a device (s) that determines the quality and / or quantity of release of components of a detergent-active, cleaning-active or caring-active preparation. In cases where the compartmenting devices have such a function, either components of the detergent-active, cleaning-active or care-active preparations can be dispensed into the liquor at different times of the washing, cleaning and / or care process (qualitative control) ), or different amounts of certain (qualitatively identical) preparations can be put into the fleet (quantitative control).

In the former case, a flexible, preferably elastic, hollow body, for example, several compartments whose walls have a different solubility (or temperature of dissolution) in water or in the liquor. The compartments contain (washing, cleaning, care) active components for the first, second and possibly further (washing, cleaning, care) gears, which have different compositions, and set these at different times or at different Temperatures of the washing, cleaning or care process free.

In the second exemplary case, the flexible, preferably elastic, hollow bodies - for example only - have walls and compartmentalizing devices incorporated into the materials are that dissolve at different temperatures or under different other boundary conditions. For example, in the compartment walls first small holes form, which allow only a weak mass transfer between individual compartments and the outside environment and thus deliver only small amounts of a washing active, cleaning active or care-active preparation in the fleet; under other, later adjustable conditions, the holes or pores are enlarged because in other conditions soluble wall components dissolve; larger volumes may be exchanged between the interior of the compartment (s) and the outside environment (ie, the liquor) through the larger holes, thereby adjusting the desired higher concentrations of the detergent-active, cleaning-active or caring-active preparation in the liquor.

• – die Zeit, d. h. der Ablauf einer bestimmten Zeit, in der die Wände der flexiblen, vorzugsweise elastischen, Hohlkörper und/oder die Kompartimentierungs-Einrichtungen mit einem bestimmten Medium, beispielsweise mit einer wäßrigen Flotte, in Kontakt stehen, wobei eine zuverlässige Zeitsteuerung eine lineare Lösungskinetik voraussetzt;
• – die Temperatur, d. h. das Erreichen eines bestimmten Temperaturwertes im Verlauf des Temperaturprofils des Wasch-, Reinigungs- oder Pflegevorgangs; die Steuerung über die Temperatur stellt insbesondere bei Geschirrpflegemitteln wegen der mit jeder Stufe des Pflegevorgangs steigenden Temperatur eine zuverlässige und damit bevorzugte Ausführungsform dar;
• – der pH-Wert, d. h. die Einstellung eines bestimmten pH-Wertes im Verlauf eines Wasch-, Reinigungs- oder Pflegevorgangs durch Komponenten der waschaktiven, reinigungsaktiven oder pflegeaktiven Zubereitung oder das Verlassen eines bestimmten pH-Wertes nach Zerfall einer den pH-Wert beeinflussenden oder bestimmenden Komponente;
• – die Ionenstärke;
• – die mechanische Stabilität, welche – in Abhängigkeit von der Zeit, von der Temperatur oder von anderen Parametern – ein die Desintegration bestimmender Faktor sein kann;
• – die Permeabilität für eine bestimmte – vornehmlich gasförmige oder flüssige – Komponente; und dergleichen.

Possible "switches" of the release of the components by the compatibilizers are, in particularly preferred embodiments, physicochemical parameters which effect the disintegration of the compartmentalizing devices and / or the walls of the flexible, preferably elastic, hollow bodies. Examples thereof, which should not be construed as limiting, are

• - The time, ie the passage of a certain time in which the walls of the flexible, preferably elastic, hollow body and / or the compartmentalization devices with a certain medium, for example, with an aqueous liquor in contact, with a reliable timing a linear Requires solution kinetics;
• - The temperature, ie the achievement of a certain temperature value in the course of the temperature profile of the washing, cleaning or care process; the control over the temperature is a reliable and therefore preferred embodiment, especially for tableware because of the rising with each stage of the care process temperature;
• The pH, ie the setting of a specific pH in the course of a washing, cleaning or care operation by components of the washing-active, cleaning-active or care-active preparation or leaving a certain pH after decomposition of a pH or pH value determining component;
• - the ionic strength;
• Mechanical stability, which may be a factor determining disintegration, depending on time, temperature or other parameters;
• The permeability for a particular component, mainly gaseous or liquid; and the same.

The aforementioned parameters are only examples that are not intended to limit the invention.

In a further preferred embodiment, the compartmentation device (s) is (are) the activity of at least one component of a detergent-active, cleaning-active or care-active preparation-controlling device (s). This embodiment is particularly useful in cases where it is necessary that the release of one or more active ingredients a washing active, cleaning active or care-active preparation with a given kinetics in the washing, cleaning or rinsing liquor takes place. A particular example is a so-called "controlled release" release, which can be controlled according to the parameters given above on the properties of the wall of the flexible, preferably elastic, hollow body and / or the Kompartimentierungsseinrichtungen. In this way, a destructive effect of the liquor or alone of the water on the active substance can be reduced and the substance can be actively released into the liquor for a longer time.

It is a further preferred embodiment that one or more compartmentalizing device (s) contain a part or the total amount of at least one component of at least one detergent-active, cleaning-active or care-active preparation. This can be achieved with particular advantage by incorporating one or more component (s) of at least one detergent-active, cleaning-active or care-active preparation into the material of the compartmenting device. Examples of such substances have been mentioned above in connection with the flexible, preferably elastic, hollow body forming material and include (but are not limited to) components which are relatively small in the detergent, cleaning or care agent portions are contained and therefore relatively poorly incorporated into large mass approaches wash-active, cleaning-active or nurturing preparations. A very simple incorporation succeeds in the materials of Kompartimentierungs facilities, and from this also a reliable, controllable release in the course of washing, cleaning or maintenance process succeeds. By suitable choice of materials, the release can also be carried out with "controlled release" kinetics.

A further, likewise preferred embodiment consists in that one or more compartmentalizing device (s) consist in part or in total of at least one component of at least one washing-active, cleaning-active or care-active preparation. This is preferred because the compartmenting device is thus not only a component of the detergent, cleaning agent or care agent portion influencing or even controlling the kinetics of the release, but at the same time also a component of the success of the washing, cleaning or maintenance process is involved. Due to the wide variety of available materials, there are numerous examples for this embodiment; particularly preferred are compartmentalizing devices consisting of or comprising (meth) acrylic acid and its derivatives (salts, esters) comprising polymers.

According to a further preferred embodiment, the compartmentalizing device (s) consist of an interface between two adjacent components of a washing-active, cleaning-active or care-active preparation or an interface between two adjoining washing-active, cleaning-active or care-active preparations. In preferred embodiments of the invention, this may be the case, for example, when washing-active, cleaning-active or care-active preparations are blown by means of suitable measures, for example by coextrusion in the blow molding compound, from which the hollow body with and without compartments is then blow-molded via a preform. In these cases, activity-reducing or otherwise disadvantageous influences of the washing-active, cleaning-active or care-active preparations can be minimized or even eliminated. There is the possibility that either individual components of a detergent-active, cleaning-active or care-active preparation are combined to form adjacent boundary surfaces or that washing-active, cleaning-active or care-active preparations which are mixtures of several components are combined to form interfaces. Both can, within the scope of the flexible, preferably elastic, hollow body according to the invention lead to detergent, cleaning agent and / or care agent portions having particularly advantageous properties, for example with good dissolution kinetics of the components in the aqueous liquors.

A further preferred embodiment consists in a detergent, cleaning agent and / or care agent portion contained in one or more flexible, preferably elastic, hollow body (s) with at least one compartment, in which the flexible, preferably elastic, hollow body of an n limiting Surface, non-spherical hollow body, one surface of which performs the function of a "lid" used to complete a process for preparing detergent, cleaning or care agent portions according to the invention, i. H. after filling the compartment (s) in the interior of the hollow body with one or more detergent-active, cleaning-active or care-active preparation (s), is applied while closing the hollow body. The "lid" particularly preferably consists of a material with controllable water solubility and can be bonded to the remaining hollow body by bonding, for example with a water-soluble adhesive, fusing, welding or another known method of joining materials. This embodiment is particularly advantageous for producing the detergent, cleaning agent or care agent portions according to the invention, since a stepwise filling of the compartment (s) with one or more detergent-active, cleaning-active or care-active preparation is possible and the handling during subsequent use leads to optimum results leads, in particular to a reliable control of the access of water or aqueous liquor to the interior of the flexible, preferably elastic, hollow body or the outlet of washing active, cleaning active or care-active preparation from the interior of the preferably blow-molded hollow body.

According to the invention, the hollow body (s) and / or the compartments contain metered quantities, i. H. Portions, preferably at least one detergent-active, cleaning-active or care-active preparation, usually measured amounts of several washing-active, cleaning-active or care-producing preparations. It is possible that the portions contain only washing active, cleansing or nourishing preparations of a particular composition. According to the invention, however, it is preferred that several, usually at least two, wash-active, cleaning-active or care-active preparations of different composition are contained in the detergent, cleaning agent and / or care agent portions. The composition may be (qualitatively) different with regard to the concentration of the individual components of the washing-active, cleaning-active or care-active preparation (quantitatively) and / or with regard to the nature of the individual components of the washing-active, cleaning-active or care-active preparation. It is particularly preferred that the components are adapted in terms of nature and concentration to the tasks that have to fulfill the detergent, cleaning agent and / or care product partial portions in the washing, cleaning and / or care process.

In the context of the present invention, the term "washing-active or cleaning-active or care-active preparation" is understood to mean all conceivable substances of relevance in connection with a washing, cleaning and / or care process. In the case of detergents and cleaners, these are primarily the actual detergents and / or cleaners with their individual components explained in more detail later in the description. These include active ingredients such as surfactants (anionic, nonionic, cationic and amphoteric surfactants), builders (inorganic and organic builders), bleaches (such as peroxy bleach and chlorine bleach), bleach activators, bleach stabilizers, bleach catalysts, enzymes, specialty polymers ( for example, those with cobuilder properties), grayness inhibitors, dyes and fragrances (perfumes), without the term being limited to these substance groups.

However, the term "washing-active or cleaning-active preparations" is also understood to mean washing auxiliaries and cleaning auxiliaries, including rinse aids. Examples of these are optical brighteners, UV protectants, so-called Soil Repellents, ie polymers which counteract re-soiling of fibers or hard surfaces (including dishes), as well as silver protectants, colorants and decolorizing agents. Care products, such as laundry treatment agents, in particular fabric softeners or dishwashing detergent additives, such as rinse aids, are also considered according to the invention as detergent-active or as cleaning-active or care-active preparations.

According to the invention, the detergent, cleaning agent or care agent portions are contained in one or more flexible, preferably elastic, hollow body (s) and / or one or more compartments. The exact shape of the hollow body is just as critical in this context as its size; The only requirement in this regard is that shape and size are in accordance with the later use, ie use in a washing, cleaning and / or care process, in particular in conventional washing machines or dishwashers. Conceivable hollow bodies in spherical, ellipsoidal, cubic, cuboid, trapezoidal, conical or pyramid or Trochoidform; Cuboid or trochoid-shaped hollow bodies have proven themselves in accordance with the invention and can therefore be used to advantage.

Usually, however, the filled with washing, cleaning or care products hollow body according to the invention are added directly to the laundry in the washing drum of a washing machine.

It is particularly preferred if the washing and / or cleaning agent contained in the hollow body and / or the compartments comprises anionic surfactants and / or nonionic surfactants as the washing-active substances. It is even more preferable if the washing and / or cleaning agent contained in the hollow body and / or the compartments is free of cation surfactant and / or amphoteric surfactants.

The hollow bodies and / or compartments of the hollow body, which contain washing, cleaning and / or care-active preparation, can be combined with one another for the detergent, cleaning agent and / or care agent portion according to the invention. In this case, according to the invention, it is not bound to merely connect two compartments. Rather, it is also possible to add further compartments and / or hollow bodies which contain washing, cleaning and / or care-active preparation in further compartments. For reasons of process economy, compartments and / or hollow bodies are preferred which have flat connecting surfaces. Of course, it is not bound to connect only filled hollow body with and / or compartments with each other to detergent according to the invention, detergent or care product portion. Rather, it is also possible and preferred to include hollow bodies which contain washing, cleaning or care-active preparation in the compartments (A) or (B), with further compartments containing washing, cleaning and / or care-active preparations, preferably blow-molded compartments and / or to connect hollow bodies. Here, in particular the joining of, preferably blow-molded, hollow bodies with tablets has proven to be particularly advantageous. The respective compartments of the water-soluble hollow body can be filled with a different content and / or a different composition of washing, cleaning and / or care-active active substances.

Another requirement is, but not necessarily, that the hollow body be used for release in an aqueous environment. This may, but need not, be limiting to the choice of agents that can be used in the present invention.

It is preferred if at least one enzyme-containing compartment free of bleach and / or at least one bleach-containing compartment is free of enzyme.

It is advantageous if the wall thickness of the hollow body and / or the compartments are preferably formed by means of blow molding so that the enzymes contained in at least one hollow body and / or in at least one compartment at least partially or completely before the contained in the or at least one other compartment Bleaching agent are released into the aqueous application liquor.

Surprisingly, it has been found that certain water-soluble thermoplastics or polymeric fabrics produced therefrom, in particular polyvinyl alcohol and partially hydrolyzed polyvinyl acetate, are permeable to water vapor. It has now been found that the coated means are able to absorb water by means of the water vapor permeability of the enveloping hollow body material and thus increase their volume. The increase in volume of the agent leads to a "pumping" of the filled liquid-tight closed hollow body and thus contributes in addition to the production of elastically deformable, water-soluble hollow body, which show a "plump" appearance at. According to the invention therefore preferred are means for filling the hollow body, which have a water content which is below the equilibrium value, the agent has in the portion when stored at 30 ° C and a relative humidity of 80%, particularly preferably when stored at 23 ° C. and a relative humidity of 50%.

To develop the washing performance, the washing and cleaning agent portions may contain surface-active substances from the group of anionic, nonionic, zwitterionic or cationic surfactants, with anionic surfactants being clearly preferred for economic reasons and because of their power spectrum.

The portioned washing, care or cleaning agents can be formulated as a detergent, as a cleaning agent or as a care product, depending on which ingredients are enclosed by the hollow body with and without compartments. In addition to laundry detergents, for example, detergents for machine or manual dishwashing, universal household cleaner, toilet cleaner, glass cleaner etc. produce. Depending on the application, the choice of ingredients in the washing, care or cleaning compositions, which are present within the hollow body with and without compartments may be different. Important ingredients of these compositions are described below.

The laundry, care and / or cleaning compositions preferably contain surfactant (s) using anionic, nonionic, cationic and / or amphoteric surfactants. From an application point of view, preference is given to mixtures of anionic and nonionic surfactants in the case of textile detergents, where the proportion of anionic surfactants should be greater than the proportion of nonionic surfactants.

Of washing technology interest, the C ₁₂ -C ₁₆ alkyl sulfates and C ₁₂ -C ₁₅ alkyl sulfates and C ₁₄ -C ₁₅ alkyl sulfates are preferred. Also 2,3-alkyl sulfates, which, for example, according to the U.S. Patents 3,234,258 or 5,075,041 are manufactured and can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants.

Also, the sulfuric acid monoesters of straight chain or branched C _7-21 alcohols ethoxylated with 1 to 6 moles of ethylene oxide, such as 2-methyl branched C _9-11 alcohols containing on average 3.5 moles of ethylene oxide (EO) or C _12-18 fatty alcohols with 1 to 4 EO, are suitable. Due to their high foaming behavior, they are only used in detergents in relatively small amounts, for example in amounts of from 1 to 5% by weight.

Further suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and the monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols. Preferred sulfosuccinates contain C _8-18 fatty alcohol residues or mixtures of these. Particularly preferred sulfosuccinates contain a fatty alcohol residue derived from ethoxylated fatty alcohols, which in themselves constitute nonionic surfactants (see description below). Sulfosuccinates, whose fatty alcohol residues are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are again particularly preferred. Likewise, it is also possible to use alk (en) ylsuccinic acid having preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

As further anionic surfactants are particularly soaps into consideration.

Builders which may be present in the compositions according to the invention are in particular phosphates, silicates, aluminum silicates (in particular zeolites), carbonates, salts of organic di- and polycarboxylic acids and mixtures of these substances.

The use of the generally known phosphates as builders is possible according to the invention, unless such use should not be avoided for ecological reasons. Among the large number of commercially available phosphates, the alkali metal phosphates, with a particular preference for pentasodium or pentapotassium triphosphate (sodium or potassium tripolyphosphate), have the greatest importance in the washing and cleaning agent industry.

Alkalimetaliphosphate is the summary term for the alkali metal (especially sodium and potassium) salts of various phosphoric acids, in which one can distinguish metaphosphoric (HPO ₃ ) _n and orthophosphoric H ₃ PO _{4 in} addition to high molecular weight representatives. The phosphates combine several advantages: they act as alkali carriers, prevent lime deposits on machine parts or lime incrustations in fabrics and also contribute to the cleaning performance.

Sodium dihydrogen phosphate, NaH ₂ PO ₄ , exists as a dihydrate (density 1.91 gcm ^-3 , melting point 60 °) and as a monohydrate (density 2.04 gcm ^-3 ). Both salts are white powders which are very soluble in water and which lose their water of crystallization when heated and at 200 ° C into the weak acid diphosphate (disodium hydrogen diphosphate, Na ₂ H ₂ P ₂ O ₇ ), at higher temperature in sodium trimetaphosphate (Na ₃ P ₃ O ₉ ) and Maddrell's salt (see below). NaH ₂ PO _{4 is} acidic; It arises when phosphoric acid is adjusted to a pH of 4.5 with sodium hydroxide solution and the mash is sprayed. Potassium dihydrogen phosphate (potassium phosphate primary or monobasic potassium phosphate, KDP), KH ₂ PO ₄ , is a white salt of 2.33 gcm ^-3 density, has a melting point of 253 ° [decomposition to form potassium polyphosphate (KPO ₃ ) _x ] and is light soluble in water.

Disodium hydrogen phosphate (secondary sodium phosphate), Na ₂ HPO ₄ , is a colorless, very slightly water-soluble crystalline salt. It exists anhydrous and with 2 moles (density 2.066 gcm ^-3 , loss of water at 95 °), 7 moles (density 1.68 gcm ^-3 , melting point 48 ° with loss of 5H ₂ O) and 12 moles of water (density 1.52 gcm ^-3 , melting point 35 ° with the loss of 5H ₂ O), becomes anhydrous at 100 ° C. and on more intense heating passes into the diphosphate Na ₄ P ₂ O ₇ . Disodium hydrogen phosphate is prepared by neutralization of phosphoric acid with soda solution using phenolphthalein as an indicator. Dipotassium hydrogen phosphate (secondary ad dibasic potassium phosphate), K ₂ HPO ₄ , is an amorphous white salt that is readily soluble in water.

Trisodium phosphate, tertiary sodium phosphate, Na ₃ PO ₄ , are colorless crystals which have a density of 1.62 gcm ^-3 as dodecahydrate and a melting point of 73-76 ° C (decomposition), as decahydrate (corresponding to 19-20% P ₂ O ₅ ) have a melting point of 100 ° C and in anhydrous form (corresponding to 39-40% P ₂ O ₅ ) have a density of 2.536 gcm ^-3 . Trisodium phosphate is readily soluble in water under alkaline reaction and is prepared by evaporating a solution of exactly 1 mole of disodium phosphate and 1 mole of NaOH. Tripotassium phosphate (tertiary or tribasic potassium phosphate). K ₃ PO ₄ , is a white, deliquescent, granular powder of density 2.56 gcm ^-3 , has a melting point of 1340 ° and is readily soluble in water with an alkaline reaction. It arises z. Example, when heating Thomasschlacke with coal and potassium sulfate. Despite the higher price, the more soluble, therefore highly effective, potassium phosphates are often preferred over the corresponding sodium compounds in the detergent industry.

Tetrasodium diphosphate (sodium pyrophosphate), Na ₄ P ₂ O ₇ , exists in anhydrous form (density 2.534 gcm ^-3 , melting point 988 °, also indicated 880 °) and as decahydrate (density 1.815-1.836 gcmm ^-3 , melting point 94 ° with loss of water) , For substances are colorless, in water with alkaline reaction soluble crystals. Na ₄ P ₂ O ₇ is formed by heating disodium phosphate to> 200 ° or by reacting phosphoric acid with soda in a stoichiometric ratio and dehydrating the solution by spraying. The decahydrate complexes heavy metal salts and hardness agents and therefore reduces the hardness of the water. Potassium diphosphate (potassium pyrophosphate), K ₄ P ₂ O ₇ , exists in the form of the trihydrate and is a colorless, hygroscopic powder with a density of 2.33 gcm ^-3 , which is soluble in water, the pH being 1% Solution at 25 ° 10.4.

Condensation of NaH ₂ PO ₄ or KH ₂ PO ₄ results in higher mol. Sodium and potassium phosphates, in which one can distinguish cyclic representatives, the sodium or Kaliummetaphosphate and chain types, the sodium or potassium polyphosphates. In particular, for the latter are a variety of names in use: hot or cold phosphates, Graham's salt, Kurrolsches and Maddrell's salt. All higher sodium and potassium phosphates are collectively referred to as condensed phosphates.

The technically important pentasodium triphosphate, Na ₅ P ₃ O ₁₀ (sodium tripolyphosphate), is an anhydrous or with 6H ₂ O crystallizing, non-hygroscopic, white, water-soluble salt of the general formula NaO- [P (O) (ONa) -O] _n - Na with n = 3. In 100 g of water dissolve at room temperature about 17 g, at 60 ° about 20 g, at 100 ° about 32 g of the salt water-free salt; after two hours of heating the solution to 100 ° caused by hydrolysis about 8% orthophosphate and 15% diphosphate. In the preparation of pentasodium triphosphate, phosphoric acid is reacted with sodium carbonate solution or sodium hydroxide solution in a stoichiometric ratio and the solution is dehydrated by spraying. Similar to Graham's salt and sodium diphosphate, pentasodium triphosphate dissolves many insoluble metal compounds (including lime soaps, etc.). Pentakaliumtriphosphat, K ₅ P ₃ O ₁₀ (potassium tripolyphosphate), for example, in the form of a 50 wt .-% solution (> 23% P ₂ O ₅ , 25% K ₂ O) in the trade. The potassium polyphosphates are widely used in the washing and cleaning industry. There are also sodium potassium tripolyphosphates which can also be used in the context of the present invention. These arise, for example, when hydrolyzed sodium trimetaphosphate with KOH: (NaPO ₃ ) ₃ + 2KOH → Na ₃ K ₂ P ₃ O ₁₀ + H ₂ O

These are used according to the invention exactly as sodium tripolyphosphate, potassium tripolyphosphate or mixtures of these two; Mixtures of sodium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of potassium tripolyphosphate and sodium potassium polyphosphate or mixtures of sodium tripolyphosphate and potassium tripolyphosphate and sodium potassium tripolyphosphate can also be used according to the invention.

Suitable crystalline layered sodium silicates have the general formula NaMSi _x O _{2x + 1} H ₂ O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and preferred values for x 2 , 3 or 4 are. Preferred crystalline layered silicates of the formula given are those in which M is sodium and x assumes the values 2 or 3. In particular ₂ Si ₂ 0 ₅ · yH ₂ O, both β- and δ-sodium Na preferred ,.

It is also possible to use amorphous sodium silicates with a Na ₂ O: SiO ₂ modulus of from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2.6, which Delayed and have secondary washing properties. The dissolution delay compared with conventional amorphous sodium silicates may have been caused in various ways, for example by surface treatment, compounding, compaction / densification or by overdrying. In the context of this invention, the term "amorphous" is also understood to mean "X-ray amorphous". This means that the silicates do not yield sharp X-ray reflections typical of crystalline substances in X-ray diffraction experiments, but at most one or more maxima of the scattered X-rays having a width of several degrees of diffraction angle. However, it may well even lead to particularly good builder properties if the silicate particles provide blurred or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of size 10 to a few hundred nm, values of up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates also have a dissolution delay compared with the conventional water glasses. Particularly preferred are compacted / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates.

The finely crystalline, synthetic and bound water-containing zeolite used is preferably zeolite A and / or P. As zeolite P, zeolite ^MAP® (commercial product from Crosfield) is particularly preferred. Also suitable, however, are zeolite X and mixtures of A, X and / or P. Commercially available and preferably usable in the context of the present invention is, for example, a cocrystal of zeolite X and zeolite A (about 80% by weight of zeolite X) ), produced by the company CONDEA Augusts S. p.

The zeolite can be used as a spray-dried powder or else as undried, still moist, stabilized suspension of its preparation. In the event that the zeolite is used as a suspension, it may contain minor additions of nonionic surfactants as stabilizers, for example 1 to 3 wt .-%, based on zeolite, of ethoxylated C ₁₂ -C ₁₈ fatty alcohols having 2 to 5 ethylene oxide groups , C ₁₂ -C ₁₄ -fatty alcohols having 4 to 5 ethylene oxide groups or ethoxylated isobidecanols.

Again preferred from this group are citric acid, tartaric acid, succinic acid, malonic acid, adipic acid, maleic acid, fumaric acid, oxalic acid and also polyacrylic acid. Also, the anhydrides of these acids can be used as Acidifizierungsmittel, in particular maleic anhydride and succinic anhydride are commercially available.

A commercially available as an acidifier in the context of the present invention is also preferably usable Sokalan ^® DCS (trademark of BASF), a mixture of succinic acid (max. 31 wt .-%), glutaric acid (max. 50 wt .-%) (and adipic acid at most 33% by weight).

Another possible group of ingredients are the chelating agents. Chelating agents are substances which form cyclic compounds with metal ions, with a single ligand occupying more than one coordination site on a central atom, i. H. at least "bidentate". In this case, normally stretched compounds are closed by complex formation via an ion into rings. The number of bound ligands depends on the coordination number of the central ion.

Common and preferred chelating agents in the context of the present invention are, for example, polyoxycarboxylic acids, polyamines, ethylenediaminetetraacetic acid (EDTA) and nitrilotriacetic acid (NTA). Also, complex-forming polymers, ie polymers which carry functional groups either in the main chain itself or laterally to it, which can act as ligands and react with suitable metal atoms usually with the formation of chelate complexes, can be used according to the invention. The polymer-bound ligands of the resulting metal complexes can originate from only one macromolecule or belong to different polymer chains. The latter leads to the crosslinking of the material, provided that the complex-forming polymers were not previously crosslinked via covalent bonds.

For the purposes of this patent application, polycarboxylic acids a) are understood as meaning carboxylic acids, including monocarboxylic acids, in which the sum of carboxyl groups and the hydroxyl groups contained in the molecule is at least 5. Complexing agents from the group of nitrogen-containing polycarboxylic acids, in particular EDTA, are preferred. In the case of the alkaline pH values of the treatment solutions required according to the invention, these complexing agents are at least partially present as anions. It is irrelevant whether they are introduced in the form of acids or in the form of salts. In the case of use as salts, alkali metal, ammonium or alkylammonium salts, in particular sodium salts, are preferred.

Scale-inhibiting polymers can likewise be present in the agents according to the invention. These substances, which could be constructed chemically different, for example, from the groups of low molecular weight polyacrylates having molecular weights between 1000 and 20,000 daltons, with polymers having molecular weights below 15,000 daltons are preferred.

Scale-inhibiting polymers may also have co-builder properties. As organic cobuilders, it is possible in particular to use polycarboxylates / polycarboxylic acids, polymeric polycarboxylates, aspartic acid, polyacetals, dextrins, further organic cobuilders (see below) and phosphonates in the dishwasher detergents according to the invention. These classes of substances are described below.

Useful organic builder substances are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids meaning those carboxylic acids which carry more than one acid function. These are, for example, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), if such use is not objectionable for ecological reasons, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures thereof.

The acids themselves can also be used. In addition to their builder effect, the acids also typically have the property of an acidifying component and thus also serve to produce a lower and milder pH of detergents or cleaners. In particular, here are Citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures thereof.

As a builder or coating inhibitor further polymeric polycarboxylates are suitable, these are, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those having a molecular weight of 500 to 70000 g / mol.

For the purposes of this document, the molecular weights stated for polymeric polycarboxylates are weight-average molar masses M _{w of} the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was carried out against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. These data differ significantly from the molecular weight data in which Polystyrolsutbnsäuren be used as a standard. The molar masses measured against polystyrenesulfonic acids are generally significantly higher than the molecular weights specified in this document.

Suitable polymers are in particular polyacrylates, which preferably have a molecular weight of 500 to 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates, which have molar masses of from 1000 to 10 000 g / mol, and particularly preferably from 1000 to 4000 g / mol, may again be preferred from this group.

Both polyacrylates and copolymers of unsaturated carboxylic acids, monomers containing sulfonic acid groups and optionally further ionic or nonionogenic monomers are particularly preferably used in the compositions according to the invention. The sulfonic acid group-containing copolymers are described in detail below.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally from 2000 to 70000 g / mol, preferably from 20,000 to 50,000 g / mol and in particular from 30,000 to 40,000 g / mol.

The (co) polymeric polycarboxylates can be used either as a powder or as an aqueous solution. The content of (co) polymeric polycarboxylates in the compositions is preferably 0.5 to 20% by weight, in particular 3 to 10% by weight.

Also particularly preferred are biodegradable polymers of more than two different monomer units, for example those which contain as monomers salts of acrylic acid and maleic acid and vinyl alcohol or vinyl alcohol derivatives or as monomers salts of acrylic acid and 2-alkylallylsulfonic acid and sugar derivatives , Further preferred copolymers are those which preferably have as monomers acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate.

Also to be mentioned as further preferred builders polymeric aminodicarboxylic acids, their salts or their precursors. Particular preference is given to polyaspartic acids or their salts and derivatives which, in addition to cobuilder properties, also have a bleach-stabilizing action.

Further suitable builder substances are polyacetals which can be obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 C atoms and at least 3 hydroxyl groups. Preferred polyacetals are obtained from dialdehydes such as glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

Further suitable organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary, for example acid or enzyme catalyzed processes. Preferably, it is hydrolysis products having average molecular weights in the range of 400 to 500,000 g / mol. Here, a polysaccharide having a dextrose equivalent (DE) in the range of 0.5 to 40, especially 2 to 30 is preferred, where DE is a common time for the reducing effect of a polysaccharide compared to dextrose, which has a DE of 100 , is. Usable are both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 and so-called yellow dextrins and white dextrins with higher molecular weights in the range from 2000 to 30,000 g / mol.

The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. A product oxidized to C _{6 of} the saccharide ring may be particularly advantageous.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are other suitable co-builders. In this case, ethylenediamine-N, N'-disuccinate (EDDS) is preferably used in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates. Suitable amounts are in zeolithhaltigen and / or silicate-containing formulations at 3 to 15 wt .-%.

Other useful organic cobuilders are, for example, acetylated hydroxycarboxylic acids or their salts, which may optionally also be present in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and a maximum of two acid groups.

Another class of substances with cobuilder properties are the phosphonates. These are, in particular, hydroxyalkane or aminoalkanephosphonates. Among the hydroxyalkane phosphonates, 1-hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance as a co-builder. It is preferably used as the sodium salt, the disodium salt neutral and the tetrasodium salt alkaline (pH 9). Preferred aminoalkanephosphonates are ethylenediamine tetramethylenephosphonate (EDTMP), diethylenetriaminepentamethylenephosphonate (DTPMP) and their higher homologs. They are preferably in the form of neutral sodium salts, eg. B. as the hexasodium salt of EDTMP or as hepta- and octa-sodium salt of DTPMP used. The builder used here is preferably HEDP from the class of phosphonates. The aminoalkanephosphonates also have a pronounced heavy metal binding capacity. Accordingly, in particular if the agents also contain bleach, it may be preferable to use aminoalkanephosphonates, in particular DTPMP, or to use mixtures of the phosphonates mentioned.

In addition to the substances from the mentioned classes of substance, the agents may contain other conventional ingredients of detergents, care or cleaning agents, in particular bleaching agents, bleach activators, enzymes, silver protectants, dyes and fragrances of importance. These substances will be described below.

Among the compounds serving as bleaches in water H ₂ O ₂ , sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Other useful bleaching agents are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and H ₂ O ₂ -producing peracidic salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperacid or diperdodecanedioic acid.

In order to achieve an improved bleaching effect when washing at temperatures of 60 ° C and below, bleach activators can be incorporated into the detergent tablets. As bleach activators, it is possible to use compounds which, under perhydrolysis conditions, give aliphatic peroxycarboxylic acids having preferably 1 to 10 C atoms, in particular 2 to 4 C atoms, and / or optionally substituted perbenzoic acid. Suitable substances are those which carry O- and / or N-acyl groups of the stated C atom number and / or optionally substituted benzoyl groups. Preference is given to polyacylated alkylenediamines, in particular tetraacetylethylenediamine (TAED), acylated triazine derivatives, in particular 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine (DADHT), acylated glycolurils, in particular tetraacetylglycoluril (TAGU), N- Acylimides, in particular N-nonanoylsuccinimide (NOSI), acylated phenolsulfonates, in particular n-nonanoyl or isononanoyloxybenzenesulfonate (n- or iso-NOBS), carboxylic anhydrides, in particular phthalic anhydride, acylated polyhydric alcohols, in particular triacetin, ethylene glycol diacetate and 2,5-diacetoxy- 2,5-dihydrofuran.

In addition to the conventional bleach activators or in their place also so-called bleach catalysts can be incorporated into the moldings. These substances are bleach-enhancing transition metal salts or transition metal complexes such as, for example, Mn, Fe, Co, Ru or Mo saline complexes or carbonyl complexes. Mn, Fe, Co, Ru, Mo, Ti, V and Cu complexes with nitrogen-containing tripod ligands and Co, Fe, Cu and Ru ammine complexes can also be used as bleach catalysts.

As enzymes are in particular those from the classes of hydrolases such as proteases, esterases, lipases or lipolytic enzymes, amylases, cellulases or other Glykosylhydrolasen and Mixtures of said enzymes in question. All of these hydrolases in the wash contribute to the removal of stains such as proteinaceous, greasy or starchy stains and graying. Cellulases and other glycosylhydroases can also contribute to color retention and to increasing the softness of the fabric by removing pilling and microfibrils. Oxireductases can also be used for bleaching or inhibiting color transfer. Particularly suitable are bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis, Streptomyceus griseus and Humicola insolens derived enzymatic agents. Preferably, subtilisin-type proteases and in particular proteases derived from Bacillus lentus are used. These are enzyme mixtures, for example from protease and amylase or protease and lipase or lipolytic enzymes or protease and cellulase or from cellulase and lipase or lipolytic enzymes or from protease, amylase and lipase or lipolytic enzymes or protease, lipase or lipolytic enzymes and cellulase, but in particular protease and / or lipase-containing mixtures or mixtures with lipolytic enzymes of particular interest. Examples of such lipolytic enzymes are the known cutinases. Peroxidases or oxidases have also proved suitable in some cases. Suitable amylases include in particular α-amylases, iso-amylases, pullulanases and pectinases. As cellulases are preferably cellobiohydrolases, endoglucanases and β-glucosidases, which are also called cellobiases, or mixtures thereof used. Since different cellulase types differ by their CMCase and avicelase activities, the desired activities can be set by targeted mixtures of the cellulases.

The enzymes may be adsorbed to carriers or embedded in encapsulants to protect against premature degradation. The proportion of enzymes, enzyme mixtures or enzyme granules may be, for example, about 0.1 to 5 wt .-%, preferably 0.12 to about 2 wt .-%.

Enzymes are added to the prior art primarily a detergent composition, in particular added to a dish care product intended for the main rinse. Disadvantage was that the optimal effect of enzymes used limited the choice of temperature and also encountered problems in the stability of the enzymes in a strongly alkaline environment. With the washing or cleaning agent portions according to the invention, it is possible to introduce enzymes into a separate compartment and then to use them in the pre-wash and thus to use the pre-rinse cycle in addition to the main rinse for an enzyme action on contamination of the dishes.

It is therefore particularly preferred to add enzymes or enzymes to the wash-active preparation or partial portion provided for the prewash cycle and then to further comprise such a preparation with a water-soluble material of a flexible, preferably elastic, hollow body which is already soluble at low temperature. for example, to protect the enzyme-containing preparation from loss of effect due to environmental conditions. The enzymes are further preferably optimized for use under the conditions of the preschool, that is, for example, in cold water.

Advantageously, the detergent portions can then be when the enzyme preparations are liquid, as they are sometimes available commercially, because then a rapid effect can be expected, which already occurs in (relatively short and carried out in cold water) pre-wash. Even if - as usual - the enzymes are used in solid form and they are provided with a hollow body enclosure made of a water-soluble material that is already soluble in cold water, the enzymes can unfold their effect before the main wash or main cleaning. Advantage of the use of an enclosure of water-soluble material, in particular from cold water-soluble material is that the enzyme / enzymes in cold water after dissolution of the enclosure comes to effect quickly / come. Thus, their duration of action can be extended, which benefits the washing or rinsing results.

The automatic dishwashing detergents may contain corrosion inhibitors for the protection of the items to be washed or the machine, with silver protectants in particular being of particular importance in the field of automatic dishwashing. It is possible to use the known substances of the prior art. In general, silver protectants selected from the group of triazoles, benzotriazoles, bisbenzotriazoles, aminotriazoles, alkylaminotriazoles and transition metal salts or complexes can be used in particular. Particularly preferred to use are benzotriazole and / or alkylaminotriazole. In addition, cleaner formulations often contain active chlorine-containing agents which can markedly reduce the corrosion of the silver surface. In chlorine-free cleaners are particularly oxygen and nitrogen-containing organic redox-active compounds, such as di- and trihydric phenols, eg. As hydroquinone, pyrocatechol, hydroxyhydroquinone, gallic acid, phloroglucinol, pyrogallol or derivatives of these classes of compounds. Also salt and complex inorganic compounds, such as salts of the metals Mn, Ti, Zr, Hf, V, Co and Ce are frequently used. Preferred here are the transition metal salts which are selected from the group of manganese and / or cobalt salts and / or complexes, more preferably the cobalt (amine) complexes, the cobalt (acetate) complexes, the cobalt (carbonyl) complexes , the chlorides of cobalt or manganese and manganese sulfate. Also, zinc compounds can be used to prevent corrosion on the items to be washed.

As electrolytes from the group of inorganic salts, a wide number of different salts can be used. Preferred cations are the alkali and alkaline earth metals, preferred anions are the halides and sulfates. From a manufacturing point of view, the use of NaCl or MgCl ₂ in the compositions is preferred. The proportion of electrolytes in the inventive compositions is usually 0.5 to 5 wt .-%.

Non-aqueous solvents that can be used in the agents, for example, from the group of monohydric or polyhydric alcohols, alkanolamines or glycol ethers, provided they are miscible in the specified concentration range with water. Preferably, the solvents are selected from ethanol, n- or i-propanol, butanols, glycol, propane or butanediol, glycerol, diglycol, propyl or butyl diglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether , Diethylene glycol ethyl ether, propylene glycol methyl, ethyl or propyl ether, dipropylene glycol monomethyl, or ethyl ether, di-iso-propylene glycol monomethyl, or ethyl ether, methoxy, ethoxy or butoxy triglycol, 1-butoxyethoxy-2-propanol, 3 -Methyl-3-methoxybutanol, propylene glycol t-butyl ether and mixtures of these solvents. Non-aqueous solvents may be used in the liquid detergents in amounts of between 0.5 and 10% by weight, but preferably below 5% by weight and in particular below 3% by weight.

In order to bring the pH of the agent in the desired range, the use of pH adjusters may be indicated. Can be used here are all known acids or alkalis, unless their use is not for technical application or environmental reasons or for reasons of consumer protection prohibited. Usually, the amount of these adjusting agents does not exceed 5% by weight of the total formulation.

In order to improve the aesthetic impression of the agents, they can be dyed with suitable dyes. Preferred dyes, the selection of which presents no difficulty to the skilled person, have a high storage stability and insensitivity to the other ingredients of the agents and to light and no pronounced substantivity to textile fibers so as not to stain them.

Suitable foam inhibitors which can be used in the compositions are, for example, soaps, paraffins or silicone oils, which may optionally be applied to support materials. Suitable anti-redeposition agents, which are also referred to as soil repellents, are, for example, nonionic cellulose ethers such as methylcellulose and methylhydroxypropylcellulose with a proportion of methoxy groups of 15 to 30% by weight and of hydroxypropyl groups of 1 to 15% by weight, based in each case on the nonionic cellulose ether as well as the known from the prior art polymers of phthalic acid and / or terephthalic acid or derivatives thereof, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionic and / or nonionic modified derivatives thereof. Especially preferred of these are the sulfonated derivatives of the phthalic and terephthalic acid polymers.

Optical brighteners (so-called "whites") may be added to the compositions to eliminate graying and yellowing of the treated fabrics. These fabrics impinge on the fiber and cause whitening and bleaching by transforming invisible ultraviolet radiation into visible longer wavelength light, emitting the ultraviolet light absorbed from the sunlight as faint bluish fluorescence, and pure with the yellowness of the grayed or yellowed wash White results. Suitable compounds are derived, for example, from the substance classes of 4,4'-diamino-2,2'-stilbenedisulfonic acids (flavonic acids), 4,4'-distyrylbiphenyls, methylumbelliferones, coumarins, dihydroquinolinones, 1,3-diarylpyrazolines, naphthalimides, benzoxazole , Benzisoxazole and benzimidazole systems as well as heterocyclic substituted pyrene derivatives. The optical brighteners are usually used in amounts between 0.05 and 0.3 wt .-%, based on the finished composition.

Grayness inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being rebuilt. Water-soluble colloids of mostly organic nature are suitable for this purpose, for example glue, gelatine, salts of ether sulfonic acids or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Also, water-soluble polyamides containing acidic groups are suitable for this purpose. You can continue use soluble starch preparations and other than the above-mentioned starch products, for. Degraded starch, aldehyde levels, etc. Also, polyvinylpyrrolidone is useful. However, preference is given to using cellulose ethers such as carboxymethylcellulose (Na salt), methylcellulose, hydroxyalkylcellulose and mixed ethers such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, methylcarboxymethylcellulose and mixtures thereof in amounts of from 0.1 to 5% by weight, based on the compositions

If the agents are formulated as a means for automatic dishwashing, then further ingredients can be used. Machine-washed dishes are often subject to more stringent requirements today than manually-washed dishes. So even a completely cleaned of leftovers dishes is then rated as not flawless if it has after dishwasher washing whitish, based on water hardness or other mineral salts stains that come from lack of wetting agent from dried water droplets. In order to obtain crystal-clear and spotless dishes, one uses therefore successfully today rinse aid. The addition of rinse aid at the end of the washing program ensures that the water runs as completely as possible from the items to be washed, so that the different surfaces at the end of the washing program are residue-free and flawless gloss. The automatic cleaning of dishes in household dishwashers usually includes a pre-wash, a main wash, and a rinse cycle interrupted by intermediate rinses. In most machines, the pre-rinse for heavily soiled dishes is switchable, but is selected only in exceptional cases by the consumer, so that in most machines a main rinse, an intermediate rinse with pure water and a rinse cycle are performed. The temperature of the main wash cycle varies between 40 and 65 ° C, depending on the machine type and program level selection. In the rinse cycle, rinse aids are added from a dosing tank in the machine, which usually contain nonionic surfactants as the main constituent. Such rinse aids are in liquid form and are widely described in the art. Your task is primarily to prevent limescale and deposits on the dishes.

The agents can be formulated as "normal" cleaners which are used in conjunction with commercial supplements (rinse aid, regenerating salt). With particular advantage but can be dispensed with the products of the invention to the additional dosage of rinse aid. These so-called "2in1" products lead to a simplification of handling and relieve the consumer of the burden of additional dosage of two different products (cleaner and rinse aid).

Even with the use of "2in1" products, two dosing operations are required at regular intervals to operate a domestic dishwasher, because after a certain number of rinses, the regeneration salt must be replenished in the water softening system of the machine. These water softening systems consist of ion exchange polymers which soften the hard water entering the machine and are regenerated by a rinsing with salt water following the washing program.

• i) ungesättigten Carbonsäuren
• ii) Sulfonsäuregruppen-haltigen Monomeren
• iii) gegebenenfalls weiteren ionischen oder nichtionogenen Monomeren

These copolymers cause the dishware treated with such agents to become significantly cleaner in subsequent cleanings than do the dishware which has been rinsed by conventional means.

As an additional positive effect occurs a shortening of the drying time of the treated with the detergent dishes, d. H. the consumer can take the dishes from the machine earlier and reuse them after the cleaning program has ended. The invention is characterized by an improved "cleanability" of the treated substrates in subsequent cleaning operations and by a significant reduction in the drying time compared to comparable agents without the use of sulfonic acid-containing polymers.

Drying time in the context of the teaching according to the invention is generally understood to mean the meaning of the meaning of the word, that is to say the time that elapses until a dishwashing machine is treated Dish surface dried, but in particular the time that elapses until 90% of a treated with a cleaning or rinse aid in concentrated or diluted form surface is dried.

In the case of terpolymers, particular preference is given to those containing from 20 to 85% by weight of monomer from group i), from 10 to 60% by weight of monomer from group ii) and from 5 to 30% by weight of monomer from group iii) ,

The molecular weight of the polymers used in the agents can be varied to match the properties of the polymers to the desired end use. Preferred automatic dishwashing agents are characterized in that the copolymers have molar masses of from 2000 to 200,000 gmol ^-1 , preferably from 4000 to 25,000 gmol ^-1 and in particular from 5000 to 15,000 gmol ^-1 .

The content of one or more copolymers in the compositions may vary depending on the application and the desired product performance, preferred automatic dishwashing compositions being characterized by containing the copolymer (s) in amounts of from 0.25 to 50% by weight, preferably from 0.5 to 35 wt .-%, particularly preferably from 0.75 to 20 wt .-% and in particular from 1 to 15 wt .-%.

As already mentioned above, particularly preferably both polyacrylates and the above-described copolymers of unsaturated carboxylic acids, monomers containing sulfonic acid groups and optionally further ionic or nonionogenic monomers are used in the compositions. The polyacrylates were described in detail above. Particularly preferred are combinations of the above-described sulfonic acid-containing copolymers with low molecular weight polyacrylates, for example in the range between 1000 and 4000 daltons. Such polyacrylates are commercially available under the trade name Sokalan ^® PA15 and Sokalan ^® PA25 (BASF).

The agents can also be formulated as fabric softeners or washing additives. Depending on the intended use further ingredients can be used. Softener compositions for rinse-aid are broadly described in the art. Typically, these compositions contain as active ingredient a cationic quaternary ammonium compound which is dispersed in water. Depending on the content of active substance in the finished plasticizer composition, this is referred to as dilute, ready-to-use products (active substance contents below 7% by weight) or so-called concentrates (active substance content above 7% by weight). Because of the lower volume and the concomitantly reduced packaging and transport costs, the textile softener concentrates have advantages from an ecological point of view and have become more and more prevalent in the market. Due to the incorporation of cationic compounds, which have only a low water solubility, conventional softener compositions are in the form of dispersions, have a milky-cloudy appearance and are not translucent. For reasons of product aesthetics, it may also be desirable to provide the consumer with translucent, clear fabric softeners which visually stand out from the known products.

As textile-softening active substance, portioned fabric softeners preferably contain cationic surfactants which have already been described in detail above (formulas XII, XIII and XIV). Particularly preferred "soft care portions" contain so-called ester quats. While there are a lot of possible According to the invention, compounds of this class of substance are used with particular preference esterquats which can be prepared in a manner known per se by reacting trialkanolamines with a mixture of fatty acids and dicarboxylic acids, optionally subsequent alkoxylation of the reaction product and quaternization, as described in US Pat DE 195 39 846 is described.

The esterquats prepared in this way are outstandingly suitable for the preparation of portions which can be used as fabric softeners. Since, depending on the choice of trialkanolamine, the fatty acids and the dicarboxylic acids and the quaternizing a variety of suitable products can be prepared and used in the compositions of the invention, a description of the preferred esterquats to be used over their preparation route is more precise than the specification of a general formula.

The abovementioned components which react with one another to give the esterquats which are preferably to be used can be used in varying proportions relative to one another. In the context of the present invention, portioned fabric softeners are preferred in which a reaction product of trialkanolamines with a mixture of fatty acids and dicarboxylic acids in a molar ratio of 1:10 to 10: 1, preferably 1: 5 to 5: 1, optionally alkoxylated and then in is quaternized in known manner, in amounts of 2 to 60, preferably 3 to 35 and especially 5 to 30 wt .-% is included. Particularly preferred is the use of triethanolamine, so that further preferred portioned fabric softener of the present invention, a reaction product of triethanolamine with a mixture of fatty acids and dicarboxylic acids in a molar ratio of 1:10 to 10: 1, preferably 1: 5 to 5: 1, the optionally alkoxylated and then quaternized in a manner known per se, in amounts of 2 to 60, preferably 3 to 35 and in particular 5 to 30 wt .-%.

As fatty acids, all acids obtained from vegetable or animal oils and fats can be used in the reaction mixture for the preparation of the esterquats. It can in the Rekationsgemisch as fatty acid quite well at room temperature non-solid, d. H. pasty to liquid, fatty acid can be used.

The fatty acids can be saturated or mono- to polyunsaturated regardless of their state of aggregation. Of course, not only "pure" fatty acids can be used but also the technical fatty acid mixtures obtained from the fats and oils cleavage, these mixtures again being clearly preferred from an economic point of view.

For example, individual species or mixtures of the following acids can be used in the reaction mixtures for preparing the esterquats for the clear aqueous fabric softeners according to the invention: caprylic acid, pelargonic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, octadecan-12-ol acid, arachic acid, behenic acid , Lignoceric acid, cerotic acid, melissic acid, 10-undecenoic acid, petroselinic acid, petroselaidic acid, oleic acid, elaidic acid, ricinoleic acid, linolaidic acid, α- and β-estarainic acid, gadoleic acid, erucic acid, brassidic acid. Of course, the fatty acids having an odd number of carbon atoms are also usable, for example undecanoic acid, tridecanoic acid, pentadecanoic acid, heptadecanoic acid, nonadecanoic acid, heneicosanoic acid, tricosanoic acid, pentacosanoic acid, heptacosanoic acid.

In the context of the present invention, the use of fatty acids of the formula XIII in the reaction mixture for the preparation of the esterquats is preferred, so that preferred portioned fabric softeners are a reaction product of trialkanolamines with a mixture of fatty acids of the formula XIII, R ¹ -CO-OH (XIII) in which R 1-CO- is an aliphatic, linear or branched acyl radical having 6 to 22 carbon atoms and 0 and / or 1, 2 or 3 double bonds and dicarboxylic acids in a molar ratio of 1:10 to 10: 1, preferably 1: 5 to 5 : 1, which is optionally alkoxylated and then quaternized in a conventional manner, in amounts of 2 to 60, preferably 3 to 35 and especially 5 to 30 wt .-% in the compositions.

Suitable dicarboxylic acids which are suitable for the preparation of the esterquats to be used in the compositions are, in particular, saturated or mono- or polyunsaturated α-dicarboxylic acids. Examples include the saturated species of oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, sebacic acid, undecane and dodecanoic acid, brassylic acid, tetra- and pentadecanoic acid, thapic acid and hepta-, octa- and nonadecanoic, eicosane and heneicosanoic acid as well as phellogenic acid. Preferably used in the reaction mixture are dicarboxylic acids, those of general formula XXIII, so that portioned agents according to the invention are preferred which are a reaction product of trialkanolamines with a mixture of fatty acids and dicarboxylic acids of formula XIV, HO-OC- [X] -CO-OH (XIV) in which X is an optionally hydroxy-substituted alkylene group having 1 to 10 carbon atoms, in a molar ratio of 1:10 to 10: 1, preferably 1: 5 to 5: 1, which is optionally alkoxylated and then quaternized in a conventional manner, in quantities from 2 to 60, preferably 3 to 35 and in particular 5 to 30 wt .-% in the compositions.

Among the multitude of esterquats which can be prepared and used, those in particular in which the alkanolamine is trethanolamine and the dicarboxylic acid adipic acid have once again proved particularly suitable. Thus, in the context of the present invention, agents are particularly preferred which comprise a reaction product of triethanolamine with a mixture of fatty acids and adipic acid in a molar ratio of 1: 5 to 5: 1, preferably 1: 3 to 3: 1, which is subsequently in a manner known per se in amounts of 2 to 60, preferably 3 to 35 and in particular 5 to 30 wt .-% in the compositions

The agents can - regardless of whether they are formulated as a laundry detergent, laundry detergent or softener - also be equipped with other additional benefits. Here, for example, color transfer inhibiting compositions, anti-gray formula agents, ironing facilitators, fragrance release agents, soil repellency improvers, antibacterial agents, UV protectants, color refreshing agents, etc. can be formulated. Some examples are explained below:
Since textile fabrics, in particular of rayon, rayon, cotton and their mixtures, can crumple because the individual fibers against bending, kinking. Pressing and squeezing transverse to the fiber direction are sensitive, the compositions of the invention may contain synthetic crease inhibitors. These include, for example, synthetic products based on fatty acids, fatty acid esters. Fatty acid amides, alkylol esters, alkylolamides or fatty alcohols, which are usually reacted with ethylene oxide, or products based on lecithin or modified phosphoric acid ester.

For controlling microorganisms, the compositions of the invention may contain antimicrobial agents. Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between bacteriostatic agents and bactericides, fungistats and fungicides, etc. Important substances from these groups are, for example, benzalkonium chlorides, alkylarylsulfonates, halophenols and phenolmercuric acetate, and the compounds according to the invention can be completely dispensed with.

In order to prevent undesirable changes in the agents and / or the treated textiles caused by oxygen and other oxidative processes, the agents may contain antioxidants. This class of compounds includes, for example, substituted phenols, hydroquinones, catechols and aromatic amines, as well as organic sulfides, polysulfides, dithiocarbamates, phosphites and phosphonates.

Increased comfort may result from the additional use of antistatic agents added to the compositions. Antistatic agents increase the surface conductivity and thus allow an improved drainage of formed charges. External antistatic agents are generally substances with at least one hydrophilic molecule ligand and give a more or less hygroscopic film on the surfaces. These mostly surface-active antistatic agents can be subdivided into nitrogen-containing (amines, amides, quaternary ammonium compounds), phosphorus-containing (phosphoric acid esters) and sulfur-containing (alkyl sulfonates, alkyl sulfates) antistatic agents. Lauryl (or stearyl) dimethylbenzylammonium chlorides are suitable as antistatic agents for textiles or as an additive to detergents, with an additional finishing effect being achieved.

To improve the water absorbency, the rewettability of the treated textiles and to facilitate the ironing of the treated textiles, for example, silicone derivatives can be used in the compositions. These additionally improve the rinsing out of the compositions according to the invention by their foam-inhibiting properties. Preferred silicone derivatives are, for example, polydialkyl or alkylaryl siloxanes in which the alkyl groups have one to five carbon atoms and are completely or partially fluorinated. Preferred silicones are polydimethylsiloxanes, which may optionally be derivatized and are then amino-functional or quaternized or have Si-OH, Si-H and / or Si-Cl bonds. The viscosities of the preferred silicones are in the range between 100 and 100,000 centistokes at 25 ° C, wherein the silicones can be used in amounts of between 0.2 and 5 wt .-%, based on the total agent.

Finally, the agents may also contain UV absorbers which are applied to the treated fabrics and improve the lightfastness of the fibers. Compounds having these desired properties include, for example, the non-radiative deactivating compounds and derivatives of benzophenone having substituents in the 2- and / or 4-position. Also suitable are substituted benzotriazoles, phenyl-substituted acrylates (cinnamic acid derivatives) in the 3-position, optionally with cyano groups in the 2-position, salicylates, organic Ni complexes and natural substances such as umbelliferone and the body's own urocanic acid.

Further conceivable additives, which are preferred in specific embodiments, are surfactants which, in particular, can influence the solubility of the water-soluble wall of the flexible, preferably elastic, hollow body or the compartmentation device, but can also control their wettability and foaming on dissolution, as well as foam inhibitors, but also Bitter substances that can prevent accidental ingestion of such hollow body or parts of such hollow body by children.

Fragrances are added to the detergent, cleaning agent and / or care product portions in order to improve the aesthetic overall impression of the products and to provide the consumer in addition to the technical performance (fabric softening result) a sensory typical and distinctive product. As perfume oils or perfumes, individual perfume compounds can be used, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-t-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethylacetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate. Ethers include, for example, benzyl ethyl ether. The aldehydes include, for. B. linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, purple and bourgeonal.

The ketones include the ionones, α-isomethylionone, and methyl cedryl ketone. The alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol. The hydrocarbons mainly include terpenes such as limonene and pinene. Preference is given to using mixtures of different fragrances which are coordinated with one another in such a way that together they produce an attractive fragrance note. Such perfume oils may also contain natural fragrance mixtures as are available from plant sources. Examples are pine, citrus, jasmine, patchouli, rose or ylang-ylang oil. Also suitable are nutmeg oil, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil and orange blossom oil, neroliol, orange peel oil and sandalwood oil.

Usually, the content of perfumes in the range up to 2 wt .-% of the total detergent, cleaning agent or care portion.

The fragrances can be incorporated directly into the detergent-active, cleaning-active or care-active preparation (s); but it can also be advantageous to apply the fragrances to carriers, which enhance the adhesion of the perfume to the laundry and provide a slower fragrance release for long-lasting fragrance of textiles. As such carrier materials, for example, cyclodextrins have been proven. The cyclodextrin-perfume complexes can additionally be coated with other auxiliaries.

The perfumes and fragrances can in principle be contained in each of the partial portions (washing-active or cleaning-active or care-active preparations) of the detergent, cleaner or care agent portions according to the invention. However, it is particularly preferred that they are in a detergent in a provided for the post-wash cycle or fabric conditioner portion detergent portion or in a detergent, especially in a dish care product, provided in a rinse or rinse cycle Teil-Reinigungsmittel- Portion, especially part-care-portion, are included. They must therefore according to the invention of a water-insoluble only in the conditions (especially at the temperature) of the Nachwaschgangs or after-care, in the conditions (especially at the temperature) of the previous washes or rinses water-insoluble material of the flexible, preferably elastic, hollow body or the compartmenting device (s). This is according to the invention For example, with a plurality of compartments in a flexible, preferably elastic, hollow body comprising detergent, cleaning agent or care portion feasible.

The detergent, cleaning or care agent portions contain in a flexible, preferably elastic, hollow body with and without compartments one or more detergent-active, cleaning-active and / or care-active preparations in amounts such that they are suitable for a washing, cleaning and / or Care process is sufficient. Of course, a dosage of two units (hollow body) is possible under special conditions (heavily soiled, eg heavily greased laundry, heavily harnessed dishes).

A particularly preferred embodiment comprises a detergent, cleaning agent or care agent portion which is contained in one or more flexible, preferably elastic, hollow body (s) with at least one compartment and which contains at least one, preferably several, wash-active, cleaning-active (s). or care-active preparation (s) in one or more forms from the group of powders, granules, extrudates, pellets, beads, tablets, tabs, rings, blocks, briquettes, solutions, melts, gels, suspensions, dispersions, emulsions, foams and gases. Gels are preferred and most preferred are liquid detergents, cleansers and / or conditioners. The form of the washing-active, cleaning-active and / or care-active preparation contained in one or more compartments of the flexible, preferably elastic, hollow body is therefore not limited, as long as the hollow body can be used in the intended manner. It is to be regarded as a significant advantage that for the first time the use of fluid phases in detergent, detergent and / or care product portions is possible and suitable for the administration of such fluid phases detergent, cleaning agent and / or care portion provided. Thus, in the compartments of a hollow body, liquids, gels, gases or foams may be closed alone or together with solid components in one or more compartments and, in use, contacted with the articles to be washed, cleaned or nurtured. This achieves a new freedom in the formulation of detergents, cleaning agents and / or care products.

The detergent, cleaning or care agent portions disclosed herein consist of an outer mold containing one or more fillings. The hollow mold can be divided by partitions into several compartments, whereby several fillings can be present within the same hollow body separated from each other. In addition to the compatibility with the material of the mold, no demands are placed on the fillings, so that both solid and liquid phase systems can be portioned.

Produced are also filled hollow body, which only partially from a disintegrate under washing, cleaning or Pflegegbedingungen, the / the hollow body (s) dimensional stability imparting, preferably blow-molded material, while the remaining parts of the enclosure not necessarily flexible, preferably elastic, im have to be defined above.

Preferably, the washing, cleaning and / or care agent portions can be used by their division into several separate areas for the separation of incompatible active ingredients. The table below gives a non-limiting overview of possible drugs and their division into different compartments.

EXAMPLE 1:

On a discontinuously bagged blow-fill-seal machine of the company Rommelag / Kocher-Plastik type "bottelpack plant 2012" (with four-bladed head, sequentially flowed) was PVA blend "KSE Mowiflex LPTC 221" with increasing temperature profile (180 ° C extruder zones , 196 ° C blowing head) melted thermoplastic in the extruder and simultaneously blown out to form four tube preforms. Extruder speeds were in the range above 50 rpm. The residence time of the blow molding compound was 3 min.

The four tube preforms ran with uniform feed from the tuyere down freely and were their downwardly open ends in the still thermoplastic state, directly after exiting the nozzle, in a clamping cycle by two closing, longitudinally parallel clamping tubes welded together and thereby closed , As a result of the supporting air blown evenly into the tube preforms from the four respective cylindrical, coaxial filling tubes and the pressure building up at the closed end of the tube, the tubular blanks were balloon-like, especially in their lower area, to be thinner wall thicknesses. These areas of thinner preform wall thickness formed by the further manufacturing process, the area of the subsequent bottom jaw of a blow-fill-seal hollow body according to the invention by the now blown to the vorvorehnte Schlauchvorformlinge blow mold there by another welding step by moving lower jaws this to a first closed only on one side Hollow body prepared for filling with means after molding to the final hollow body geometry.

Comparative Example:

Hollow bodies are prepared analogously to Example 1, which undergo no additional stretching step of the preform. The comparison hollow bodies are filled with self-formulation, as in Example 1.

To measure and assess the total dissolution time of the hollow body, the hollow body material is tested without content for its residue behavior under specified conditions.

The amount of residue is visually compared to a reference panel and the solubility assessed by means of a score system from 1 (very soluble) to 10 (poorly soluble).

The test is carried out with service water (17 ° dH + 2 ° dH) and the following devices:
Digital thermometer Testo 700 of the company Testo GmbH & Co, heating plate of the company Franz MORAT KG (GmbH & Co.) Type: M 22/1, 1000 ml beaker (high form), magnetic stir bar with approx. 4.5 cm length, Stopwatch, filter fabric: single jersey 100% cotton, Fa. Trigema, dark blue, ca. 15 × 15 cm

Execution:

It is cut open a filled hollow body and pushed out the contents. The film thus obtained is divided into 4 approximately equal parts by means of scissors. The beaker is filled with 800 g of service water, the temperature of which is 14 + 1 ° C. It is constantly stirred with the stirring fish, the set stirring speed is between 500-600 revolutions per minute. The 4 pieces of film are now added at the same time in the prepared water and stirred for 15 min.
