Description

The present invention relates to the technical field of solid surfactant compositions for providing surfactant-containing liquors for textile treatment, in particular for cleaning textiles.

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

Solid textile treatment agents have the advantage that, in contrast to liquid textile treatment agents, they require no preservatives and the ingredients contained therein (such as bleaches or enzymes) can be incorporated more stable. 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.

Consumers have become accustomed to conveniently metering pre-portioned engineered fabric treatment agents, such as detergent pouches, and use these products in the form of tablets (solid textile treatment agents) or in the form of pouches (also: pillows or pouches), which are typically filled with at least one liquid fabric treatment agent are. However, in addition to the aforementioned advantages, the use of liquids has the disadvantage, for example, that leakages in the bag of the portion cause the liquid textile treatment agent to run out.

Disposable portions in water-soluble bags enjoy popularity with the consumer also because of the attractive appearance of the disposable portion. 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. In particular, transparent products are perceived by the consumer as visually appealing. Solid surfactant compositions used for textile cleaning are usually opaque. It is therefore also an object to provide translucent to transparent solid surfactant compositions.

From the consumer's point of view, it is also desirable to combine the advantages of the solid and liquid dosage forms and to provide a form of administration that is improved over the prior art, in particular for conventionally liquid detergents or cleaners. For this purpose, a one-time portioning of the components contained must be possible and at the same time a visually pleasing appearance for the consumer, in particular transparency or translucency, can be achieved.

In particular, when using solid moldings which have to be dissolved or dispersed for application to a substrate in an aqueous medium, it is particularly important that the solid dissolves well in water. When dosing disposable portions together with the laundry in the drum of the washing machine, the disposable portion must be incorporated quickly into the aqueous liquid liquor, so that in the drum with the molding in contact standing laundry (eg textile) not by permanent over-concentration of the ingredients Tenside composition suffers damage. It is therefore the object of the invention to provide solid-form surfactant compositions, in particular as a single-use portion in the form of a particulate shaped body, which dissolve readily in water or can be dispersed therein upon contact with water.

From the publication WO 02/086074 A1 For example, viscoelastic, solid surfactant compositions having a storage modulus of 40,000 to 800,000 Pa are known. The viscoelastic surfactant compositions disclosed therein are liquid crystalline surfactant phases. The preparation of the viscoelastic surfactant compositions of the prior art is dependent on the phase behavior of the respective surfactants present, which limits the formulation freedom with regard to the selection of the surfactants and their amounts used.

From the publication WO 2010/108002 Flowable surfactant compositions are known which contain from 0.01 to 1% by weight of dibenzylidenesorbitol as a gelator compound.

It has been found that by formulating a composition containing at least one surfactant and at least one organic gelator compound having a molecular weight <1000 g / mol, a solubility in water of less than 0.1 g / L (20 ° C). and a structure containing at least one hydrophobic group (preferably at least one carbocyclic aromatic moiety) and at least two groups selected from -OH, -NH-, or mixtures thereof (preferably at least one benzylidene-allylitol compound) this object can be achieved. However, this is the use of high amounts of organic Gelator compound of more than 1 wt .-% necessary. It has now surprisingly been found that the object can be dissolved in an aqueous medium at a surfactant content of at least 30 wt .-% and with gelator amounts of 0.01 to 1 wt .-%, when a mixture of selected surfactants is used ,

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

The viscoelastic, solid surfactant composition incorporates all the advantages of a liquid composition, provides an aesthetic product form with a good dissolution profile in the context of textile treatment with excellent performance profile on the substrate. From the WO 2010/108002 For example, structured liquid surfactant compositions containing a maximum of 1% by weight of a benzylidenalditol compound as a structuring agent are known. Viscoelastic, solid surfactant compositions containing benzylidenalditol compounds are not described therein.

The viscoelastic, solid surfactant composition of the present invention is storage and dimensionally stable. The said viscoelastic, solid surfactant composition exhibits almost no syneresis even after prolonged storage.

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.

The water solubility is determined at 20 ° C in deionized water.

As is known and therefore according to the invention, a substance (eg a composition) is viscoelastic and firm when at 20 ° C. the storage modulus of the substance 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 memory module and the loss module, as well as the determination of the values of these modules, are notoriously familiar to the person skilled in the art (cf. Christopher W. Macosco, "Rheology Principles, Measurements and Applications", VCH, 1994 , P. 121 ff. Or Gebhard Schramm, "Introduction to Rheology and Rheometry", Karlsruhe, 1995 , S 156 ff. Or WO 02/086074 A1 , P. 2, third paragraph to p. 4, end of 1st paragraph).

The rheological characterization is in the context of this invention with a Rotationsrheometer, for example, TA-Instruments, type AR G2, Malvem "Kinexus", using a cone-plate measuring system with 40 mm diameter and 2 ° opening angle at a temperature of 20 ° C performed. These are shear stress controlled rheometers. However, the determination can also be carried out with other 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 In this case, the shear stress amplitude is increased at a constant frequency of, for example, 1 Hz, and the modules G 'and G "are plotted in a log logarithmic plot. On the x-axis, either 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 compositions according to the invention, a deformation amplitude of 0.1% has proven suitable. The modules G 'and G "are plotted against the frequency in a log-log plot.

A substance (e.g., a composition) is liquid according to the definition of the invention when in the liquid state at 20 ° C and 1013 mbar.

A chemical compound or its structural unit is organic if its molecular structure contains at least one covalent bond between carbon and hydrogen.

A chemical compound or its structural unit is in contrast to the definition "organic" then inorganic, if their molecular structure contains no covalent bond between carbon and hydrogen.

The average molar masses indicated in the context of this application for polymeric ingredients are-unless explicitly stated otherwise-always weight-average molar masses M _w , which can in principle be determined by means of gel permeation chromatography with the aid of an RI detector, the measurement being expedient against an external standard he follows.

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, fabrics or textiles (such as clothing) may be used. The portions according to the invention are preferably used to provide a surfactant-containing liquor in the context of automatic cleaning processes, as described, for example, in US Pat. be executed by a washing machine for textiles.

"At least one" as used herein refers to 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In the context of ingredients of the compositions described herein, this indication does not refer to the absolute amount of molecules but to the nature of the ingredient. Thus, "at least one inorganic base" 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.

The viscoelastic, solid surfactant composition according to the invention is preferably transparent or translucent. If a mixture according to the invention in the spectral range between 380 nm and 780 nm has a residual light power of at least 20% based on the reference measurement, it is considered transparent in the sense of the invention.

The transparency of the surfactant composition according to the invention can be determined by various methods. The Nephelometric Turbidity Unit (NTU) is often used as a measure of transparency. It is a e.g. unit used in water treatment for turbidity measurements, e.g. in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values are measured for cloudy surfactant compositions, while low values are determined for clear, transparent surfactant compositions.

The HACH Turbidimeter 2100Q Turbidimimeter from Hach Company, Loveland, Colorado (USA) is used with the calibration gauges StablCal Solution HACH (20 NTU), StablCal Solution HACH (100 NTU) and StablCal Solution HACH (800 NTU). , all can also be ordered from Hach Company. The measurement is filled in a 10 ml measuring cuvette with cap with the composition to be examined and the measurement is carried out at 20 ° C.

At an NTU value (at 20 ° C.) of 60 or more, surfactant compositions which can be recognized by the naked eye in the sense of the invention have a perceptible haze. Therefore, it is preferred that the surfactant compositions of the invention have an NTU (at 20 ° C) of at most 120, more preferably at most 110, more preferably at most 100, most preferably at most 80.

In the context of the present invention, the transparency of the solid-state agents according to the invention was determined by a transmission measurement in the visual light spectrum over a wavelength range from 380 nm to 780 nm at 20 ° C. For this purpose, a reference sample (water, deionized) is first measured in a photometer (Messrs. Specord S 600 from Analytik Jena) with a cuvette which is transparent in the spectrum to be examined (layer thickness 10 mm). Subsequently, the cuvette is filled with a sample of the surfactant composition according to the invention and measured again. The sample is filled in the liquid state and solidified in the cuvette and then measured.

It is preferred if the transparent surfactant composition of the invention has a transmission (20 ° C) of at least 25%, more preferably at least 30%, more preferably at least 35%, more preferably at least 40%, especially at least 50%, most preferably at least 60% %, having.

All of the abovementioned preferred embodiments of the surfactant composition according to the invention and of the shaped article according to the invention are likewise preferred for the provision of a portion according to the invention.

In order to prevent the application of the portion of the direct skin contact of the user with the viscoelastic, solid, surfactant composition, the molded body is preferably coated with water-soluble material. Such a coating has also proved to be favorable with regard to the storage stability of the shaped bodies according to the invention used in the portions.

Within the scope of a preferred embodiment, said shaped body of the portion is coated on the surface with at least one water-soluble material, preferably with at least one water-soluble polymer. The coating can be effected for example by spraying a solution or by immersion in a melt, wherein in the latter method, the melting temperature is preferably below the sol-gel temperature. It may again be preferred to spray the shaped bodies coated with at least one water-soluble material with at least one pulverulent solid. Preferred means for Abpuderung are the aforementioned (vide supra).

According to another embodiment as a pouch, a portion according to the invention may comprise at least one chamber with walls of water-soluble material into which at least one shaped body of a viscoelastic, solid-form surfactant composition of the first subject of the invention is introduced. Summed up over all chambers of the portion, the compositions made up in total yield the portion of the portion to be dosed (here a textile treatment agent). Corresponding portions of this embodiment are well known to those skilled in the art as pouch products.

A chamber is a space bounded by walls (e.g., by a foil), which may exist even without the material to be dosed (possibly changing its shape). A layer of a surface coating thus does not explicitly fall under the definition of a wall. The water-soluble material in a pouch forms the walls of the chamber and thereby envelops the compositions of the fabric treatment agent.

Soluble in water is a material, if at 20 ° C 0.1 g of the material with stirring (stirring speed magnetic stirrer 300 rpm, stirring bar: 6.8 cm long, diameter 10 mm, beaker 1000mL low form the company. Schott, Mainz) within Dissolve 600 seconds in 800 mL of water so that no single solid particles of the material are visible to the naked eye.

The water-solubility of the film-forming material used for the production of pouches for wrapping can be determined by means of a square film of said material (film: 22 × 22 mm having a thickness of 20 μm) fixed in a square frame (inside edge length: 20 mm) 76 μm) according to the following measurement protocol. Said framed film is immersed in 800 mL of distilled water heated to 20 ° C in a 1 liter beaker with a circular bottom surface (Schott, Mainz, 1000 mL beaker, low mold) so that the surface of the clamped film is at right angles to the Bottom surface of the beaker is arranged, the upper edge of the frame is 1 cm below the water surface and the lower edge of the frame is aligned parallel to the bottom surface of the beaker 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 water-soluble material generally used for coating the shaped body preferably contains at least one water-soluble polymer. It is particularly preferable that the water-soluble material contains polyvinyl alcohol or a polyvinyl alcohol copolymer.

Suitable water-soluble material and 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 each case in the range from 10,000 to 1,000,000 gmol ^-1 , preferably from 20,000 to 500,000 gmol ^-1 , particularly preferably from 30,000 to 100,000 gmol ^{. 1} and in particular from 40,000 to 80,000 gmol ^-1 .

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 the water-soluble material comprises at least one 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%.

In addition, polymers selected from the group comprising acrylic acid-containing polymers, polyacrylamides, oxazoline polymers, polystyrenesulfonates, polyurethanes, polyesters, polyether polylactic acid, and / or mixtures of the above polymers may be added to the water-soluble material.

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.

The water-soluble material of the sheet material used for providing the pouch walls has a preferred thickness in a range of 65 to 180 μm, especially 70 to 150 μm, more preferably 75 to 120 μm.

In the said water-soluble material of the coating of the shaped body of the portion or the walls of the pouch of the portion is preferably incorporated to increase the product safety a bittering agent. Corresponding embodiments of the water-soluble material with bittering agent are in the documents EP-B1-2 885 220 and EP-B1-2 885 221 described. A preferred bittering agent is selected from the aforementioned bittering agents (vide supra), in particular denatonium benzoate.

Portions of the present invention in the form of a pouch can be made by either vertical fill seal (VFFS) or thermoforming techniques. Particularly preferably, walls of at least one chamber are created by sealing at least one film of water-soluble material, in particular by sealing in the context of a form-fill-seal method. The thermoforming process generally includes forming a first layer of water-soluble film material to form at least one protrusion for receiving at least one composition therein, filling the composition into the respective protrusion, covering the composition-filled protrusions with a second layer of water-soluble one Film material and sealing the first and second layers together at least around the protrusions.

For the preparation of a liquid mixture was first prepared according to a column of Table 1 without temperature-sensitive ingredients (enzymes, perfume) and to a temperature above the sol-gel temperature is heated. The heated mixture is cooled with stirring to 30 ° C, the remaining ingredients added. 19 g of the resulting solution was quickly added to a cube-well mold. The temperature of the solution was gradually lowered to room temperature in the well. After solidification, the molded body was removed from the trough. The molded bodies E1 and E2 prepared in this way each had a loss modulus of the order of 10 ³ Pa. The compositions V1, V2 and V3 were liquid, ie no shaped body of a viscoelastic, solid surfactant composition was formed in the trough. Composition V3 was also inhomogeneous and formed two phases. Storage modulus and yield point of compositions V1 to V3 were therefore not determined.

All moldings were transparent.
