Description

"Portion to provide surfactant-containing fleets"

The present invention relates to the technical field of portions as dosing to

Providing surfactant-containing liquors for substrate treatment, in particular for cleaning hard surfaces such as e.g. Dishes, or for cleaning textiles.

Detergents or cleaners are usually in solid form (for example as a powder or tablets) or in liquid form (or as a flowing gel). In particular, liquid detergents or cleaners are becoming increasingly popular with consumers.

Solid detergents or cleaning agents have the advantage that, in contrast to liquid washing or cleaning agents, they do not require any preservatives and the constituents contained in them (such as, for example, bleaching agents or enzymes) can be incorporated more stably. Liquid supply forms are increasingly gaining acceptance on the market, in particular due to their rapid solubility and the associated rapid availability of the active ingredients contained. This offers the consumer the possibility, for example, to use time-reduced rinse programs for dishwashing applications and still obtain a good cleaning performance. To guarantee this also for pre-portioned compositions, the portions must have a total of good solubility in the solvent of the liquor, usually in water, and dissolve as far as possible without residue.

Consumers have become accustomed to conveniently dosing pre-portioned automatic detergents or dishwashing detergents, such as dishwashing or detergent pouches, and use these products in the form of tablets (solid detergents or cleaners) or in the form of pouches (also: pillows or pouches), which are commonly used are filled with at least one liquid washing or cleaning agent. However, in addition to the aforementioned advantages, the use of liquids has the disadvantage, for example, that leaks in the sachet of the portion cause the liquid detergent or cleaning agent to run out.

Disposable portions in water-soluble bags enjoy the consumer not only because of increasing popularity, because the consumer with the chemical composition is no longer in contact, but not least because of the attractive appearance of the bag. The appearance of the dosage form is becoming increasingly important. In addition to a good cleaning performance and a sufficient storage stability, a good appearance is one of the reasons for choosing a product.

From the point of view of the consumer, it is also desirable to combine the advantages of the forms of supply of solid and liquid medium and one over the prior art To provide improved dosage form especially for usually liquid detergents or cleaning agents. For this purpose, a one-time portioning of the components contained must be possible and at the same time a visually appealing appearance for the consumer can be achieved.

Surprisingly, it has been found that by formulating a flexible phase in the form of a viscoelastic shaped body which is combined with a granular mixture as a different phase (such as a powdered phase), this goal can be achieved. It is particularly suitable if the granular mixture is free-flowing, as a result of the process, a more targeted filling of the water-soluble casing, in particular when filling a cavity produced by deep drawing, can be achieved. In addition, the visual appearance of the granular mixture (eg powder) compared to a compressed tablet can be better changed, in particular texture differences, such as coarse and fine particles and particles or areas with different colors, total or as colored speckles, can so to improve a visually appealing appearance can be used. The granular mixture also provides, without the addition of disintegrants, an improved solubility compared to compressed tablets.

It has been found that by providing a portion having at least one phase of a granular mixture of a solid composition and at least one phase in the form of a viscoelastic, solid shaped article of a second composition containing a benzylidenalditol compound, the above problems are solved. An object of the invention is therefore in the first embodiment, a portion for providing a surfactant-containing liquor, comprising at least one chamber with wall of water-soluble material, wherein the portion comprises an agent, based on the total weight of the agent, a total amount of 0.1 to 80 wt % of at least one surfactant, said agent comprising at least two phases, and

Benzylidenalditol compound of the formula (I) contains,

wherein

* - for a single covalent bond between an oxygen atom of the

Alditol skeleton and the rest provided,

R ⁴ , R ⁵ and R ⁶ independently represent a hydrogen atom, a halogen atom, a C 1 -C 4 -alkyl group, a cyano group, a nitro group, an amino group, a carboxyl group, a hydroxy group, a group --C (= O) -NH -NH ₂ , a group -NH-C (= O) - (C ₂ -C 4 -alkyl), a C ₁ -C 4 -alkoxy group, a C ₁ -C 4 -alkoxy-C ₂ -C 4 -alkyl group, two of the radicals together with the Residual molecule form a 5- or 6-membered ring, with the proviso that the second composition of the viscoelastic, solid-shaped

Shaped body has a storage modulus between 10 ³ Pa and 10 ⁸ Pa, preferably between 10 ⁴ Pa and 10 ⁸ Pa and a loss modulus (each at 20 ° C, a deformation of 0.1% and a frequency of 1 Hz) and the memory module in the frequency range between 10 ^{~ 2} Hz and 10 Hz is at least twice greater than the loss modulus. More preferably, the second Composition of the viscoelastic, solid-shaped molding a storage modulus in a range of 10 ⁵ Pa to 10 ⁷ Pa.

To further optimize the stability properties of said shaped body, it is preferred if the storage modulus is at least five times greater than the loss modulus, more preferably at least ten times greater than the loss modulus (in each case at 20 ° C., a deformation of 0.1%). and a frequency of 1 Hz).

The compositions of the invention preferably have a flow limit. The yield stress refers to the smallest stress (force per area) above which a plastic substance behaves rheologically like a liquid. It is given in Pascal (Pa).

The flow limit of the compositions was measured using a rotary rheometer from TA-Instruments, type AR G2. This is a so-called

Schubspannungskontrolliert.es rheometer. For measuring a yield point with a

shear stress controlled rheometers are various methods in the literature

described to those skilled in the art.

For the determination of the yield points in the context of the present invention, the following was carried out at 20 ° C:

The samples were loaded in the rheometer in a "stepped-flow procedure" with a gradually increasing shear stress σ with time

Shear stress in the course of 10 minutes at 10 points per shear decadence from the smallest possible value (e.g., 2 mPa) to e.g. 10 Pa can be increased. The time interval is chosen such that the measurement is carried out "quasi-statically", ie that the deformation of the sample can be brought into equilibrium for every given shear stress value.As a function of this shear stress, the equilibrium deformation γ of the sample is measured If the investigated sample has a yield point, two distinct areas can be distinguished in this plot: Below a certain shear stress, one finds a purely elastic one

Deformation according to Hooke's law. The slope of the curve γ (σ) (log-log plot) in this area is one. Above this shear stress, the flow range begins and the slope of the curve is suddenly higher. The shear stress at which the bending of the curve takes place, ie the transition from the elastic to a plastic deformation, marks the yield point. A convenient determination of the break point is possible by applying tangents to the two curve parts. Samples without yield point do not show a characteristic kink in the function γ (σ). The solid-form, viscoelastic composition according to the invention preferably has a yield point in the range from 8 to 350 Pa, more preferably from 10 to 320 Pa (each measured with a rotational rheometer, cone-plate measuring system with 40 mm diameter and 2 ° opening angle at a temperature of 20 ° C).

All definitions and preferred embodiments below, unless otherwise defined, apply equally to the first embodiment and the second embodiment.

The viscoelastic, solid composition according to the invention combines in the

Providing a surfactant-containing liquor all the application benefits of a liquid

Composition and can be incorporated into the portion along with the granular mixture to achieve an aesthetic product shape with a good dissolution profile and excellent performance profile on the substrate. From WO 2010/108002 structured liquid surfactant compositions are known, the maximum 1 wt .-% of a

Benzylidenalditol compound as Strukturant contained. Viscoelastic, festive

Compositions containing benzylidenalditol compounds are not described therein.

The viscoelastic solid composition of the present invention is stable in storage and shape, taken alone or in combination with the granular portion of the portion, especially when the viscoelastic solid composition and the granular mixture are in direct contact. The viscoelastic composition exhibits no syneresis even after prolonged storage. If the granular mixture is in direct contact with the viscoelastic composition of the shaped body, then both phases do not mix even after prolonged storage. The composition of the granular mixture also remains stable.

One serving is an independent dosing unit with at least one chamber. Over all

Chambers summed up give the total in it ready-made compositions the good to be dosed good portion (here a remedy). A chamber is a space delimited by walls (for example by a foil), which also without the material to be dosed (possibly under

Change of its form) can exist. A layer of a surface coating thus does not explicitly fall under the definition of a wall.

The water-soluble material forms walls of the chamber and thereby envelops the

Compositions of the agent.

The wall is according to the invention of a water-soluble material. The water solubility of the material can be determined by means of a quadratic frame (edge length on the inside: 20 mm) fixed square film of said material (film: 22 x 22 mm with a thickness of 76 μιη) according to the following measurement protocol. Said framed film is in 800 mL Tempered water heated to 20 ° C in a 1 liter beaker with a circular

Soil surface (Schott, Mainz, beaker 1000 mL, low mold) immersed so that the surface of the clamped film is arranged at right angles to the bottom surface of the beaker, the upper edge of the frame is 1 cm below the water surface and the lower edge of the frame parallel to the bottom surface of the beaker is oriented such that the lower edge of the frame along the radius of the bottom surface of the beaker and the center of the lower edge of the frame is located above the center of the radius of the beaker bottom. The material should dissolve with stirring (stirring speed magnetic stirrer 300 rpm, stirring bar: 6.8 cm long, diameter 10 mm) within 600 seconds in such a way that with the naked eye, no single solid-shaped film particles are more visible. The walls are preferably made of a water-soluble film. This film may according to the invention preferably have a thickness of at most 150 μιη (more preferably of at most 120 μιη). Preferred walls are therefore made of a water-soluble film and have a thickness of at most 150 μιη (more preferably of at most 120 μιη, most preferably of at most 90 μιη) on.

Such water soluble portions may be prepared by either (preferably vertical) form fill seal (FFS) or thermoforming techniques. Particularly preferably, walls of at least one chamber are produced by sealing at least one film of water-soluble material, in particular by sealing in the context of a mold-filling-sealing process (so-called form-fill-seal process). Preferred embodiments of the FFS method will be described later (vide infra).

The water-soluble material preferably contains at least one water-soluble polymer. In addition, the water-soluble material preferably contains a water-soluble film material selected from polymers or polymer blends. The wrapper may be formed of one or two or more layers of the water-soluble film material. The water-soluble film material of the first layer and the further layers, if present, may be the same or different.

It is preferable that the water-soluble material is polyvinyl alcohol or a

Contains polyvinyl alcohol copolymer.

Suitable water-soluble films as the water-soluble material are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range of 10,000 to 1,000,000 gmo, preferably 20,000 to 500,000 gmol / more preferably 30,000 to 100,000 gmor and more preferably 40,000 to 80,000 gmol ,

The production of polyvinyl alcohol is usually carried out by hydrolysis of polyvinyl acetate, since the direct synthesis route is not possible. The same applies to polyvinyl alcohol copolymers which are prepared from correspondingly polyvinyl acetate copolymers. It is preferred if at least one layer of the water-soluble material comprises a polyvinyl alcohol whose degree of hydrolysis makes up 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%.

The film material suitable as water-soluble material may additionally be added polymers selected from the group comprising acrylic acid-containing polymers, polyacrylamides, oxazoline polymers, polystyrene sulfonates, polyurethanes, polyesters, polyether polylactic acid, and / or mixtures of the above polymers.

Preferred polyvinyl alcohol copolymers include, in addition to vinyl alcohol, dicarboxylic acids as further monomers. Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and

Mixtures thereof, with itaconic acid being preferred.

Likewise preferred polyvinyl alcohol copolymers include, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its esters. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylates, methacrylates or mixtures thereof.

As a water-soluble material of the walls used sheet material has a preferred thickness in a range of 65 to 180 μιη, in particular from 70 to 150 μιη, more preferably 75 to 120 μιη, on.

In the said water-soluble material of the walls of the portion is preferably incorporated to increase product safety a bittering agent. Appropriate

Embodiments of the water-soluble material with a bittering agent are described in the publications EP-B1-2 885 220 and EP-B1 -2 885 221. A preferred bittering agent is denatonium benzoate.

Suitable water-soluble films for use as the water-soluble material of the wall of the water-soluble portion according to the invention are films sold under the name Monosol M8630 by MonoSol LLC. Other suitable films include films named Solublon® PT, Solublon® KA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or the films VF-HP from Kuraray, or HiSelon SH2312 from Nippon Gohsei.

The agent, as well as its components such as the viscoelastic, solid composition and the granular mixture, may contain, in addition to the mandatory ingredients, other optional ingredients. The total amounts of each ingredient, if necessary, are selected from predetermined weight ranges such that together with the amounts of the remaining ingredients for the said composition, based on their total weight, they add up to 100% by weight. According to the definition of the invention, a substance (eg a composition) is solid when it is in the solid state at 20 ° C. and 1013 mbar.

A fabric (e.g., a composition of a molded article) is viscoelastic and solid according to the definition known to those skilled in the art when at 20 ° C the storage modulus of the fabric is greater than the loss modulus present. When subjected to a mechanical force on the substance, it exhibits both the properties of an elastic solid and exhibits a viscosity similar to that of a liquid. The terms of the storage modulus and the loss modulus, as well as the determination of the values of these modules, are notoriously familiar to those skilled in the art (see Christopher W. Macosco, "Rheology Principles, Measurements and Applications", VCH, 1994, pp. 121 ff., Or Gebhard Schramm , "Introduction to Rheology and Rheometry", Karlsruhe, 1995, p. 156 ff. Or WO 02/086074 A1, p. 2, third paragraph to p. 4, end of 1 st paragraph).

Theological characterization is in the context of this invention with a

Rotational rheometer, for example TA-Instruments, type AR G2, Malvern "Kinexus", performed using a cone-plate measuring system with 40 mm diameter and 2 ° opening angle at a temperature of 20 ° C. These are

shear stress controlled rheometer. However, the determination can also be made with others

Instruments or measurement geometries of comparable specifications.

The measurement of the storage modulus (abbreviation: G ') and of the loss modulus (abbreviation: G ") (each unit: Pa) was carried out with the instrumentation described above in an experiment with oscillating deformation.For this purpose, in a stress sweep experiment, the determined linear viscoelastic region. Here, at a constant frequency of e.g. 1 Hz, the shear stress amplitude increased. The modules G 'and G "are in one

plotted log log plot. On the x-axis can optionally the

Shear stress amplitude or the (resulting) deformation amplitude can be plotted. The memory module G 'is constant below a certain shear stress amplitude or deformation amplitude, above which it collapses. The break point is suitably determined by applying tangents to the two curve sections. The corresponding deformation amplitude or shear stress amplitude is usually referred to as "critical deformation" or "critical shear stress".

To determine the frequency dependence of the modules, a frequency ramp, e.g. between 0.01 Hz and 10 Hz at a constant deformation amplitude. The

Deformation amplitude must be chosen so that it is in the linear range, i. below the o.g. critical deformation lies. In the case of the invention

Compositions, a deformation amplitude of 0, 1% has proven to be suitable. The modules G 'and G "are plotted against the frequency in a log-log plot. A substance (eg a composition) is liquid according to the definition of the invention if it is present in liquid state at 20 ° C. and 1013 mbar.

A chemical compound is an organic compound when the molecule of the chemical compound contains at least one covalent bond between carbon and hydrogen. This definition applies inter alia to "organic bleach activators" as a chemical compound mutatis mutandis.

A chemical compound is, inversely to the definition of the organic compound, an inorganic compound when the molecule of the chemical compound does not contain a covalent bond between carbon and hydrogen.

In the context of this application for polymeric ingredients specified mean

Molar masses are always, unless explicitly indicated otherwise

weight-average molar masses M _w , which can be determined in principle by means of gel permeation chromatography with the aid of an RI detector, wherein the measurement is expediently carried out against an external standard.

A phase in the sense of the present invention is a spatial area in which physical parameters and the chemical composition are homogeneous. A phase differs from another phase by various features, such as ingredients, physical properties, appearance, etc. Preferably, different phases can be visually distinguished. Thus, for the consumer, the at least one first phase is clearly distinguishable from the at least one second phase. If the agent of the portion according to the invention has more than one first phase, then these can preferably likewise be differentiated from one another by the naked eye, because they differ, for example, from one another in color. The same applies if two or more second phases are present. Also in this case, a visual differentiation of the phases, for example due to a color or transparency difference is preferably possible. Phases in the sense of the present invention are thus self-contained areas that can be optically distinguished from the consumer by the naked eye. The individual phases may have different properties when used.

A granular mixture is formed from a variety of loose, solid particles which in turn comprise so-called grains. A grain is a name for the particulate components of powders (grains are the loose, solid particles), dusts (grains are the loose solid particles), granules (loose, solid particles are agglomerates of several grains) and other granular mixtures. A preferred embodiment of the granular mixture of the composition of the first phase is the powder or granules. The said solid particles of the granular mixture again preferably have one Particle diameter Xso, 3 (volume average) of 10 to 1500 μιη, more preferably from 200 μιη to 1200 μιη, more preferably from 600 μιη to 1 100 μιη, on. These particle sizes can be determined by sieving or by means of a particle size analyzer Camsizer from Retsch.

The granular mixture of the solid-form composition of the present invention which is used as a first phase is preferably present in free-flowing form (particularly preferably as free-flowing powder or free-flowing granules). The agent of the portion according to the invention thus comprises at least a first phase of a free-flowing, granular mixture of a solid

Composition, as well as at least one previously defined second phase.

The flowability of a granular mixture affects its ability to trickle freely under its own weight from a Rieseltest funnel with a spout of 16.5 mm diameter. The quality of the flowability is determined, in which the flow time of 1000 ml of granular mixture from a standardized, initially closed at its outlet trickle funnel with a spout of 16.5 mm diameter by measuring the time for the complete outflow of the powder after opening the spout measured and with the discharge speed (in

Seconds) of a standard test sand whose exit velocity is defined as 100%. The defined sand mixture for calibrating the Rieselapparatur is dry sea sand.

Particularly suitable are those granular mixtures which have a flowability in% to the standard test substance stated above of greater than 40%, preferably greater than 55%, in particular greater than 60%, particularly preferably between 63% and 80%, for example between 65% and 75%. exhibit.

Lower values for the flowability are rather not suitable, since from a process engineering point of view an exact dosage of the granular mixture is necessary. In particular, the values greater than 60% have proven to be advantageous, since only small variations in the metered amount or the composition result from the good meterability of the granular mixture. The more accurate dosage leads to a constant product performance, economic losses due to overdose are thus avoided. Furthermore, it is advantageous that the granular mixtures are easy to dose, so you can achieve a faster flow of dosing. Furthermore, it is better avoided by such a good flowability that granular mixture reaches the part of the water-soluble casing, which is intended for the production of the sealed seam and should therefore remain as free as possible of granular mixture.

A surfactant-containing liquor in the context of the invention is a liquid preparation obtainable by use of a surfactant-containing dilution with at least one solvent (preferably water) for the treatment of a substrate. As a substrate, for example, hard surfaces (such as dishes) or fabrics or textiles (such as clothing) come into question. The portions according to the invention are preferably used to provide a surfactant-containing liquor in the context of mechanical cleaning processes, as used, for example, by a

Dishwasher or a washing machine for textiles are executed.

A molded body is a single body that stabilizes itself in its embossed form. This dimensionally stable body is formed from a molding compound (e.g., a composition) by deliberately placing this molding material in a predetermined shape, e.g. by pouring a liquid composition into a mold and then curing the liquid composition, e.g. as part of a sol-gel process.

"At least one" as used herein refers to 1, 2, 3, 4, 5, 6, 7, 8, 9 or more In the context of components of the compositions described herein, this indication does not refer to the absolute amount The term "at least one inorganic base" therefore means, for example, one or more different inorganic bases, ie one or more different types of inorganic bases. The amounts given, together with quantities, refer to the total amount of the corresponding type of ingredient.

If, in the context of the application, numerical ranges are defined from one number to another number, then the limit values are included in the range.

If, in the context of the application, numerical ranges are defined between a number and another number, the limits do not include the range.

In the portion according to the invention is an agent which at least two

Compositions, each forming a phase includes. Said compositions are contained in the compartment in a chamber formed of water-soluble material. In this case, each composition of the composition can be packaged in a separate chamber, or there are at least two compositions in one and the same chamber. Preferred are

Portions characterized by the fact that the first phase and the second phase are contained together in the same compartment.

The portion according to the invention may also contain more than one first phase and / or more than one second phase.

Furthermore, such portions are preferred according to the invention, in which the granular mixture of the first phase is in direct contact with the shaped body of the second phase.

The composition of the portion according to the invention contains, based on the total weight of the composition, a total amount of from 0.1 to 80% by weight of surfactant. The surfactant can be in the said solid composition of the granular mixture (ie in the first phase), in said second composition of the shaped body (ie in the second phase) or in a further composition (further phase) of the agent, or in several of these aforementioned compositions. In sum about all in the portion made up

Preferred portions contain an agent containing, based on the total weight of the composition, a total of from 0.1 to 5.0% by weight of at least one surfactant. Such agents are suitable for use according to the invention, in particular in a dishwasher. It is again particularly preferred that the agent contains at least one nonionic surfactant.

Preferred portions contain an agent which, based on the total weight of the composition, has a total amount of from 5 to 80% by weight, particularly preferably from 20 to 70% by weight, very particularly preferably from 25 to 65% by weight, of at least one surfactant contains. Portions containing such agents are suitable for use according to the invention, but in particular for use in a washing machine for textile washing. It is again particularly preferred that the agent contains at least one anionic surfactant and optionally additionally at least one nonionic surfactant.

A preferred portion according to the invention is characterized in that the agent contained therein contains at least one anionic surfactant. Portions with anionic surfactant can be used in said fields of application, but are preferably suitable for the washing of textiles, particularly preferably for use in a washing machine for textile washing, in particular for metering into the drum of a washing machine for the

Textile washing.

When the agent contained in the portion contains anionic surfactant, it is again preferred that based on the total weight of the agent anionic surfactant in a total amount of 8 to 70 wt .-%, in particular 25 to 60 wt .-%, more preferably of 30 to 40 wt .-%, is included.

The anionic surfactant used may preferably be sulfonates and / or sulfates.

As surfactants of the sulfonate type are preferably C9-i3-alkylbenzenesulfonates,

Olefinsulfonate, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, as they are, for example, from Ci2-iso-monoolefins with terminal or internal double bond Sulfonating with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation obtained. Also suitable are C 12 -is alkanesulfonates and the esters of α-sulfo fatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.

Particularly preferred agents of the inventive portions contain as anionic surfactant at least one compound of formula (T1),

in the

R ^' and R ^"are independently H or alkyl and together contain 9 to 19, preferably 9 to 15 and especially 9 to 13 C atoms, and Y ^{+ is} a monovalent cation or the nth part of an N-valent cation (especially Na ⁺ ).

Alk (en) ylsulfates are the alkali metal and in particular the sodium salts of

Sulfuric acid half esters of C 12 -18 fatty alcohols, for example from coconut fatty alcohol,

Tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C 10 -C 20 oxo alcohols and those half-esters of secondary alcohols of these chain lengths. Of washing technology interest, the Ci2-Ci6-alkyl sulfates and Ci2-Ci5-alkyl sulfates and Cw-cis-alkyl sulfates are preferred. 2,3-alkyl sulfates are also suitable anionic surfactants.

Also, fatty alcohol ether sulfates, such as the sulfuric acid monoesters of straight-chain or branched C7-2i alcohols ethoxylated with from 1 to 6 mol of ethylene oxide, such as 2-methyl-branched C9-11 alcohols having on average 3.5 moles of ethylene oxide (EO) or C12- Fatty alcohols with 1 to 4 EO are suitable.

The water solubility of polyvinyl alcohol can be improved by post-treatment with aldehydes

(Acetalization) or ketones (ketalization) are changed. As particularly preferred and particularly advantageous due to their pronounced cold water solubility, polyvinyl alcohols have been found to be acetalated or ketalized with the aldehyde or keto groups of saccharides or polysaccharides or mixtures thereof. To use extremely advantageous are the reaction products of polyvinyl alcohol and starch. Furthermore, the water solubility can be changed by complexing with Ni or Cu salts or by treatment with dichromates, boric acid, borax and thus set specifically to desired values.

wherein ^* -, n, m, R, R ² , R ³ , R ⁴ , R ⁵ and R ^{6 are} as defined in claim 1,

is brought to a temperature above the sol-gel transition temperature of the liquid composition, and then the heated liquid composition in a mold, preferably in a cavity of a mold and given in said form below the sol-gel transition temperature to form a viscoelastic, solid shaped body is cooled.

The liquid composition is cooled below the sol-gel transition temperature to cure the liquid composition. It is inventively preferred when the liquid composition for forming said shaped body to not less than 20 ° C, in particular not less than 25 ° C, more preferably not less than 30 ° C, cooled.

Depending on the material of the mold, it may be favorable for easier removal of the molding from this mold, in particular the cavity of a mold, that before the heated liquid composition is placed in the mold, preferably in the cavity of a mold, the mold with a film is lined from water-soluble material. As appropriately suitable water-soluble material or preferred water-soluble material should be resorted to the water-soluble material of the walls of the portion (vide supra).

If the mold is lined with a film before being filled with the liquid composition, then after the curing of the liquid composition to the said

remain viscoelastic, solid shaped body of the shaped body for further production of the portion of the invention in the mold. In this case, in a process for the preparation of a portion, the viscoelastic, solid shaped body in the mold, preferably in the trough mold, left and then to the molding a granular mixture of a solid composition in a mold, preferably in the same form, and

Shaped body and (preferably in contact therewith) granular mixture with a

water-soluble material such that moldings and Körmiges mixture in at least one chamber, preferably together in the same chamber, with wall of said water-soluble material are packed. Again, it is preferable that mold in the mold and granular mixture are brought into contact with a second film of water-soluble material and the second film is sealed with the film lining the mold to form at least one chamber and a sealed seam.

Another object of the present invention is a process for the preparation of portions, in particular detergent portions containing an agent having at least a first and at least one different second phase, comprising: a) providing a mold having at least one mold cavity; optionally containing a web for dividing the bottom of the mold cavity b) feeding a water-soluble film onto the mold cavity; c) forming an open chamber in the mold cavity by deforming the water-soluble film; d) filling the open chamber or parts thereof with at least a second phase as described above or the tempered, liquid composition necessary for the preparation of the second phase, as described above; e) optionally filling the open chamber or parts thereof with at least one further second phase as described above, which second phase may optionally be different from the second phase according to d); f) optionally solidifying the second phase (s); g) then filling the open chamber with at least a first phase different from the at least one second phase as described above; h) providing a second water-soluble film as a lid; i) bringing the open chamber and lid over one another to seal the portion at a sealing area; j) sealing the lid with the open chamber.

The mold comprises at least one trough (mold cavity). For example, the mold may be provided as a single mold or as part of an array of treadmill shapes, as known in the treadmill and drum process. The mold comprises an area on which the film can be placed, eg a sealing area which is typically defined around the opening of a mold cavity. The mold cavity may have different geometries, if there are edges, it is advantageous that these are rounded. Rounded edges and / or dome-shaped troughs serve to draw the film somewhat more homogeneously as the film is drawn into the trough, thereby keeping the film thickness uniform, and to avoid breaking or breaking points, which in turn results in a more stable one Portion pack leads.

Optionally, but according to a particular embodiment, the mold preferably contains at least one mold cavity which has a web for subdividing the bottom of the mold cavity. As a result, bulges or pockets form in the formed chamber, which visually create a positive appearance. In particular, if only the areas of these bulges are completely or partially, preferably almost completely filled with the / the second phase (s), this area is once again clearly separated from the granular mixture of the first phase and visually creates a particularly good appearance.

The water-soluble film can be fed from a roll and fed to the mold cavity. The foil is positioned and held on the mold. The holding can take place through suction holes on the molding surface, which is not part of the mold cavity. The film can also be held by mechanical means on the mold, such as brackets. For example, the foil may be held in place by a punch which presses on the sealing area. In the continuous production processes, e.g. Drum method and

In the method according to the invention, it is preferred that the speed of the film is adapted to the speed of the treadmill formed from the molds, so that the film is not unnecessarily thinned by adhering to a running mold.

After the film is held in place, relative to the mold cavity, is in the

Form trough a chamber formed by the film is at least partially adapted to the mold cavity. The adaptation is produced by elastic and / or plastic deformation. Preferably, the film deformation has a greater plastic than elastic portion. The deformation of the water-soluble film is e.g. produced by deep drawing or by means of suitable stamp. A preferred variant is thermoforming, by

Actuation of negative pressure (Formierdruck) in the mold cavity, this includes the mold cavity preferably small openings, preferably in the bottom region, which are connected by appropriate lines air pressure moderately connected to a vacuum pump.

After forming the open chamber, these or parts thereof are filled in step d) with the at least one second phase of the product or its tempered, liquid composition intended for solidification. As soon as the at least one second phase has solidified, if necessary after an additional period of time which is necessary for solidification, further product constituents (further second phases according to optional step e) or at least a first phase according to step g)) can then be introduced into the chamber become. In this case, the at least one first phase according to step g) is preferably free-flowing. It is preferred in the aforementioned Herste II method that the chamber containing the second phase, (in step d) is not completely filled with the / the second phase (s). In this case, the chamber can preferably only partially, preferably only in the lower region or only in the region or just above the range formed by the optional web according to a)

Bulges or pockets of the chamber are filled with the second phase (s).

If the chamber or parts thereof is filled with at least two second phases, it is preferred according to a particular embodiment that these second phases are substantially the same or differ only slightly, for example by a different dye. They preferably have a very similar, in particular the same, composition with regard to the active ingredients used (apart from excipients such as, for example, dyes). In this case, in particular migration phenomena between the second phases, and thus the expression of a non-advantageous optics during storage by, for example, inflated or shrunken phases, are avoided.

When filled with product, preferably the deformed foil is kept in the trough during filling. For example, under negative pressure, the negative pressure is broken only after the seal. The negative pressure after forming the chamber in the

Relative to the Formierdruck, a lower strength (higher pressure) may have, which only fulfills the holding function.

The chamber is filled by the introduction of at least a first and at least a second phase, in particular by those as described above as being according to the invention.

It is important that the seal area remains free of product. For example, if the chamber is at least partially elastically deformed, this elastic deformation after filling and prior to sealing should not degrade such that the product flows over and out of the open chamber and thus contaminates the seal area.

According to a particular embodiment, the lid is positioned on the open chamber so that in the next step the lid can be applied to the sealing area. The position of the lid is generally determined relative to the position of the chamber. If the chamber is moving with a moving mold in a treadmill, the lid must move equally so that the relative position to the chamber remains the same.

The lid is then applied to the open chamber, which is closed in this way. The contact between lid and foil in the sealing area thus closes the chamber.

A preferred embodiment of the seal is a material fusion between the film and the lid, for example by dissolving the film before applying the lid, or by Melting of foil and / or lid in the sealing area. Alternatively, the

Sealing by gluing, or welding.

The positioning, applying, and sealing can take place either in separate steps or simultaneously.

The mold may also comprise at least one second mold cavity, such that

Process steps a) to d) at least two open chambers are generated. The at least two chambers are formed in the same plane. It is preferred that the lid in step h) is positioned over the at least two open chambers and the lid is applied in step i) to at least both chambers for sealing the portion of a sealing area. Since the at least two chambers are connected to the same lid, the chamber remain in a certain position relative to each other, in contrast to the prior art where adjacent chambers are connected by the web formed by the thin films of the packages.

It is particularly preferred that the lid is provided as part of a tape by feeding / transferring a tape comprising at least one lid. The singulation of the lid may take place prior to positioning, after positioning but before application, during application, or after application to the chamber.

When singulated before positioning, the lid is preferably punched out.

Lid and foil can also be separated simultaneously with the sealing. The device which produces the seal by melting consists of at least two parts, one is the mold itself and the other part is a counter-punch which presses on the mold from the lid side. It is preferred that in the sealing step, the pressure exerted during sealing by the mold and further part must be less at the sealing area than the pressure exerted in the separating area. It surrounds the

Separation area the sealing area.

In the case of separation after sealing, the lid and foil are alternatively preferably separated from the band in the same step, and thus the portion packs are separated.

As an alternative, likewise preferred process for the preparation of portions according to the invention, the following is furthermore particularly suitable. This method comprises the steps of: a) providing a mold having at least one mold cavity; optionally including a web for dividing the bottom of the mold cavity; b) supplying a water-soluble film to the mold cavity; c) forming an open chamber in the mold cavity by deforming the water-soluble film; d) filling the open chamber with at least one granular mixture of the first phase; e) providing a second mold with at least one second mold cavity; optionally containing a web for dividing the bottom of the mold cavity f) feeding a second water-soluble film onto the second mold cavity; g) forming a second open chamber in the second mold cavity by deforming the water-soluble film; h) filling the second open chamber or parts thereof with at least one second phase as described above, i) optionally filling the second open chamber or parts thereof from step h) with at least one further second phase as described above ( or the tempered liquid composition necessary for the preparation of the second phase, as described above), this at least one further second phase optionally being different from the second phase according to h); j) optionally solidifying the second phase (s); k) bringing the two open chambers together to seal the sachet to a sealing area, the filled areas facing each other;

I) sealing the open chambers with each other.

Unless otherwise stated, this procedure also applies to the procedure described for the first method.

In this second method, two different chambers are formed, with one chamber containing at least a first phase and the other chamber at least a second phase.

Preferably, in step k), the chamber containing the at least one granular mixture of a first phase, in particular a granular, free-flowing mixture of a first phase, is arranged so that the mixture does not fall out.

In this case, the chamber containing the at least one second phase above / above the chamber containing the at least one first phase is then preferably arranged. In this case, the filled chamber areas to each other. It is important that the manufacture of the second phase used liquid composition in step k) is already so far solidified or gelled or no longer flowable that it does not run out of the chamber. After sealing, this results in a multiphase Einkammerpouch, which has a particularly good appearance.

For both aforementioned production methods, the following preferably applies:

For the at least one first phase that applies to the inventive cleaning agents described above. It is preferred that the at least one first phase is free-flowing. In particular, the flowability of the at least one first phase preferably has a value of greater than 55%, in particular greater than 60%, particularly preferably between 63% and 80%, for example between 65% and 75%, with respect to the standard test sand.

For the at least one second phase to be used in the method according to the invention, the one mentioned above, to which reference is explicitly made, also applies.

Depending on the method II, the second phase (s) can be clearly above or below the sealing seam plane (the first-mentioned method) or approximately at the level of the sealing seam

B e i s p e e l e

Formed bodies F1-F15 according to Tables 1 and 2 were produced.

While stirring, a mixture of the appropriate ingredients was prepared and the mixture heated to 128 ° C until all ingredients were dissolved. 10 mL of this solution was placed in a trough mold previously lined with a thermoformed polyvinyl alcohol film (M8630 from Monosol with Denatonium Benzoate integrally incorporated in the film material). The temperature of the solution was gradually lowered to room temperature in the wells. Thereafter, 15 g of a commercial, powdered machine dishwashing detergent were added to the well on the solidified, viscoelastic molding and the filled well covered with a second film M8630 and sealed. All moldings F1 to F15 have a storage module in the order of 10 ⁶ Pa, which is at least ten times larger than the loss modulus.

It has been found that even in the absence of a surfactant liquid crystalline phase by using Benzylidenalditol (here Dibenztylidensorbitol) in a special amount a stable viscoelastic, solid-like composition can be created.

The single-compartment portions obtained with these viscoelastic compositions were stable even after four weeks of storage and had a good dissolution rate of the ingredients or phases in water. The phase separation in the portion remained concise despite the contact of the granular mixture with the viscoelastic molding.

The moldings F8, F13 to F15 showed in comparison to the other moldings a glossier surface yet sufficient breaking strength.
