Cleaning agent with abrasive natural material

Description

[0001] The present invention relates to a composition comprising at least one surfactant and at least one natural material with low density and sufficient hardness.

[0002] Cleaning hard surfaces, such as floors or dishes, presents a particular challenge, especially when stubborn dirt is present. Cleaning agents, particularly hand dishwashing detergents, require not only the cleaning power of surfactants and chemical components, but also an additional performance component that arises from physical action: abrasion.

[0003] WO 2005 / 010138 A1 describes a composition that includes, for example, a powder of apricot kernels. This powder is suitable for cleaning hard surfaces as well as human skin. Various abrasives are also disclosed in US 4,457,856 A. Particles of pistachio shells are contained in cleaning agents as described in EP 2 573 157 A1. The same abrasive particles are also described in WO 2013 / 043620 A1. Plastics, hard waxes, or ceramic particles are described as abrasive particles, for example, in WO 2004 / 035720 A1.

[0004] DE 25 39 733 A1, US 2 093 660 A, US 4 051 056 A, US 4 457 856 A, DE 28 43 517 A1, DE 12 89 600 B, FR 1 371 055 A, GB 717 589 A, DE 12 56 343 B, GB 2 178 441 A, DE 27 39 776 A1 and WO 2015 / 097228 A2 describe further compositions with particles.

[0005] However, the solutions proposed so far have drawbacks. Plastic particles are usually made from petroleum and are therefore neither sustainable nor readily biodegradable. The resulting microplastics can accumulate in the environment. The long-term effects of this are unclear. Furthermore, these particles are often round. The rounder the particles, the worse their abrasive effect.

[0006] Biodegradable plastics are also known. However, these are generally only biodegradable under specific conditions, such as high pressure or high temperature. These conditions do not correspond to the normal household wastewater pathway.

[0007] The natural products proposed in the prior art, such as fruit peels or pits, are preferred from an environmental perspective. However, they typically have a low hardness, so the additional cleaning effect to be achieved here is minimal.

[0008] The object of the present invention is therefore to provide a composition that, on the one hand, exhibits good abrasive properties, and on the other hand, avoids the disadvantages of plastic particles. Surprisingly, it has been found that the object underlying the present invention is achieved by a composition comprising at least one surfactant and at least one natural material, wherein the natural material has a specific density of 1 to 4, and in particular of 1.8 to 3, and a Mohs hardness of 4 to 6, in particular of 5 to 6, and the natural material is furthermore embedded in hydrogel particles according to the invention.

[0009] The use of such natural material eliminates the need for plastics. The aforementioned Mohs hardness provides sufficient abrasiveness. Simultaneously, it prevents scratching of sensitive materials, such as glass surfaces like those found in ceramic hobs. Even manual cleaning, for example of drinking glasses, does not damage the material. Furthermore, the material according to the invention has a specific density of 1 to 4, particularly 1.8 to 3. This lower density, compared to materials described in the prior art, allows for good dispersion within the composition. The low specific density also enables an attractive visual appearance, especially in liquid compositions. In addition, the natural material can be evenly distributed and stably incorporated.This ensures that, regardless of the dosage of the composition, a sufficiently consistent amount of natural material, which in this case constitutes the abrasive, is used. "Abrasive" and "natural material" are used synonymously in this application.

[0010] Specific density, also known as relative density, describes the ratio of two densities as a dimensionless quantity. Density values ​​are usually given in relation to the density of pure water under standard conditions at 3.98 °C. The specific density of the abrasive is 1 to 4, preferably 1.5 to 3.5, more preferably 1.8 to 3, particularly 2 to 3.5, more preferably 2.0 to 2.5, and most preferably 2.3 to 2.5.

[0011] In particular, the abrasive material itself, i.e. without taking porosity into account, has a specific density of less than 1, but due to the porosity of the abrasive material, the abrasive material as a whole, i.e. the particles, has a relative density greater than 1, in particular the more specific ranges of values ​​for relative density mentioned above.

[0012] The hardness of the natural material according to the Mohs hardness scale ranges from 4 to 6, particularly from 5 to 6. Mohs hardness values ​​can be determined by comparing several materials.

[0013] Talc, for example, has a Mohs hardness of 1, meaning it can be scraped with a fingernail. Diamond has a Mohs hardness of 10, the maximum end of the scale.

[0014] A hardness of 6 or less is particularly preferred, as this ensures that even sensitive surfaces, such as ceramic hobs in the kitchen, are cleaned without being damaged. A hardness of less than 4 is disadvantageous, as it does not provide a particularly good abrasive effect.

[0015] Preferably, the abrasives have a particle size in the range of 0.1 µm to 50,000 µm, particularly from 0.1 µm to 40,000 µm, preferably from 0.5 µm to 25,000 µm, particularly from 1 µm to 10,000 µm or from 10,000 µm or less, preferably from 5 µm to 5,000 µm or from 10 µm to 1,000 µm. Abrasives with a corresponding particle size are visually perceptible to the consumer. This is of particular interest to consumers in the case of hand dishwashing detergents. This particle size is also particularly suitable for removing stubborn dirt. Larger particles would break under pressure. Furthermore, they cannot penetrate under the edges of dirt and thus detach it from surfaces.

[0016] Natural materials within the meaning of the present invention are those materials based on naturally occurring raw materials. Naturally occurring raw materials are those of natural origin, i.e., those that occur naturally in nature. The natural materials within the meaning of the present invention are sustainable and do not increase the ecological footprint. The ecological footprint is understood to be the area of ​​land required to sustainably support a person's lifestyle and standard of living. This includes areas needed for the production of clothing and food, for the provision of energy, and also for waste disposal. Physical post-processing is not excluded according to the invention.Preferred is the natural material, an inorganic material which is in particular biologically neutral and free of heavy metals, or in which these heavy metals are not mobilizable.

[0017] Preferably, the natural material is a expanded mineral or expanded glass of natural origin. Natural origin means that the mineral or glass can occur naturally in its original form. It is then expanded, resulting in a material with the appropriate density and Mohs hardness. Expanded volcanic glass is particularly preferred. Specifically, obsidian, which in its expanded form is called perlite, is a suitable volcanic glass. Perlite typically contains a residual water content of approximately 2% and has a thermal conductivity (λ) of 0.040 to 0.070 W / mK. Due to its low thermal conductivity, perlite is commonly used as a building material for thermal insulation as well as for fire protection.

[0018] The natural material preferably does not have a round shape. If a particle shape factor is determined that defines the aspect ratio of the particles to each other, a value of 1 would represent a perfectly round shape and a value of 0 a linear shape. According to the invention, the abrasive preferably has a particle shape factor of 0.1 to 0.97, in particular 0.15 to 0.9, in particular 0.20 to 0.80, preferably 0.3 to 0.70 or 0.60, with values ​​of 0.30 or 0.40 to 0.50 being particularly preferred. Particles with a particle shape factor of 1 would have hardly any abrasive effect. A completely linear shape, on the other hand, would not be stable, as such rods could be destroyed when pressure is applied.

[0019] The composition comprises at least one natural material in a proportion of 0.02 wt.% to 40 wt.%, in particular 0.05 wt.% to 30 wt.% or up to 35 wt.%, preferably 0.1 wt.% to 20 wt.% or up to 15 wt.%, and most preferably 0.2 wt.% to 5 wt.%. The composition may comprise a single natural material or mixtures of different natural materials. Preferably, it comprises a natural material as an abrasive.

[0020] The proportion of natural material in the composition depends on the specific composition. The composition is a cleaning agent for hard surfaces, preferably a cleaning agent for the manual cleaning of hard surfaces, particularly a cleaning agent for the manual cleaning of dishes, such as a hand dishwashing detergent. In this case, the proportion of abrasive is preferably 0.03% to 10% by weight. However, it is also possible that the composition is a cleaning agent for hard surfaces, such as an scouring cream. In this case, the proportion of abrasive is preferably 10% to 40% by weight, and particularly 15% to 30% by weight.

[0021] In a particularly preferred embodiment, the abrasive particles are present as part of second particles, wherein the second particles, which can also be referred to as "beads", comprise a hydrogel, the hydrogel forming a matrix for the abrasive particles. Because the abrasives are embedded in hydrogel particles, they can be well dispersed.

[0022] The second particles comprise at least one abrasive material preferably in an amount of 2 wt.% to 20 wt.%, and further preferably 4 wt.% to 18 wt.%, and further preferably 5 wt.% to 17 wt.%, and further preferably 6 wt.% to 16 wt.%, and further preferably 8 wt.% to 14 wt.%, and further preferably 9 wt.% to 11 wt.% based on the mass of the second particles.

[0023] The composition comprises the second particles with an average size of 100 micrometers to 2000 micrometers, and preferably 206 micrometers to 1894 micrometers, and further preferably 311 micrometers to 1789 micrometers, and further preferably 417 micrometers to 1683 micrometers, and further preferably 522 micrometers to 1578 micrometers, and further preferably 628 micrometers to 1472 micrometers, and further preferably 733 micrometers to 1367 micrometers, and further preferably 839 micrometers to 1261 micrometers, and further preferably 944 micrometers to 1156 micrometers.

[0024] The matrix of the second particle, in which the abrasive particles are embedded, preferably comprises carrageenan and / or agar. More preferably, the matrix comprises carrageenan and / or agar in an amount of >80 wt% based on the mass of the second particle. Furthermore, the second particles comprise (color) pigments in an amount of <5 wt%, preferably <1 wt%, based on the mass of the second particle.

[0025] Preferably, the composition comprises at least one polyacrylic acid polymer. Preferably, the polyacrylic acid polymer is an alkali-swellable, emulsion-forming polymer. In the context of the present invention, the term "polyacrylic acid polymer" is to be understood as including copolymers with monomer units other than acrylic acid, wherein the acrylic acid content is preferably > 10 wt.% based on the total weight of the polymer, and more preferably > 20 wt.%. In the context of the present application, the term "acrylic acid" is to be understood as including derivatives of acrylic acid.

[0026] The composition comprises the polyacrylic acid polymer in an amount of 0.1 wt.% to 4 wt.%, and preferably 1 wt.% to 2.5 wt.%, and further preferably 1.5 wt.% to 2.5 wt.%.

[0027] In a particular embodiment, at least one abrasive material comprises or consists of volcanic glass, especially pumice. Pumice has been found to have very good abrasive properties and, as a natural material, high environmental compatibility. Furthermore, due to its high porosity, pumice serves as a carrier for fragrances and dyes. However, because of its high porosity and low density, pumice tends to float to the surface in aqueous solutions, which is a disadvantage and particularly hinders its use as a cleaning agent.

[0028] It has now been surprisingly discovered that in an aqueous composition comprising abrasive particles of glassy volcanic rock and a polyacrylic acid polymer, the particles can be homogeneously suspended within the abrasive without floating on the surface of the composition or aggregating upon mixing. Such a composition can advantageously be used as a cleaning agent, particularly for hand dishwashing.

[0029] The composition according to the invention comprises at least one surfactant in a proportion of 5 wt.% to 35 wt.%, in particular 8 wt.% to 30 wt.%, preferably 10 wt.% to 25 wt.%. This refers to the total surfactant content. "At least one surfactant" within the meaning of the present invention means that the composition may comprise one surfactant or mixtures of several different surfactants, such as anionic surfactants, nonionic surfactants, and amphoteric surfactants. The composition particularly preferably comprises an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant, in particular at least one anionic surfactant, at least one nonionic surfactant, and at least one amphoteric surfactant.

The sodium salts are particularly preferred.

[0032] Alkyl ether sulfates (fatty alcohol ether sulfates, INCIAlkyl ether sulfates are products of sulfation reactions on alkoxylated alcohols.

[0067] It is particularly advantageous to use a combination of anionic surfactant and amphoteric surfactant, especially a biosurfactant. This combination results in a particularly good cleaning effect and, in conjunction with the preferably used thickening agent, can also contribute to a spatially particularly stable suspension of the abrasive particles.

[0068] The composition according to the invention may additionally contain one or more non-ionic surfactants, typically in an amount of 0.001 to 5 wt.%, preferably 0.01 to 4 wt.%, in particular 0.1 to 3 wt.%, especially preferably 0.2 to 2 wt.%, most preferably 0.5 to 1.5 wt.%, for example 1 wt.%.

In this case, the group (AO) a can also contain various alkylenoxy units, for example ethyleneoxy or propylenoxy units, where a is then the average total degree of alkoxylation, i.e. the sum of the degree of ethoxylation and the degree of propoxylation.Unless otherwise specified below, the alkyl groups R 1< of APG are linear unsaturated groups with the specified number of carbon atoms.

[0076] APGs are nonionic surfactants and are known substances that can be obtained using the relevant methods of preparative organic chemistry. The index number x This indicates the degree of oligomerization (DP degree), that is, the distribution of mono- and oligoglycosides, and represents a number between 1 and 10. x in a given combination must always be an integer, and here especially the values x The value can take on a value of 1 to 6. x For a specific alkyl glycoside, an analytically determined calculated value, usually a fraction. Preferably, alkyl glycosides with a medium degree of oligomerization are used. xAlkyl glycosides with a degree of oligomerization of 1.1 to 3.0 are used. From an application engineering perspective, those alkyl glycosides are preferred whose degree of oligomerization is less than 1.7 and, in particular, between 1.2 and 1.6. Xylose, but especially glucose, is preferably used as the glycosidic sugar.

[0077] The alkyl or alkenyl group R< can be derived from primary alcohols with 8 to 18, preferably 8 to 14 carbon atoms. Typical examples are capron alcohol, caprylic alcohol, capric alcohol, and undecyl alcohol, as well as their technical mixtures, such as those obtained during the hydrogenation of technical fatty acid methyl esters or during the hydrogenation of aldehydes from the Roelen oxo synthesis.

[0078] Preferably, the alkyl or alkenyl group R< is derived from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, or oleyl alcohol.

In a preferred embodiment, however, the use of cationic surfactants is omitted.

[0081] Preferred cationic surfactants are the quaternary surface-active compounds, especially those with an ammonium, sulfonium, phosphonium, iodonium or arsonium group, such as those found, for example, in... K . H. WallhäußerIn "Practice of Sterilization, Disinfection - Preservation: Germ Identification - Operational Hygiene" (5th ed. - Stuttgart; New York: Thieme, 1995), antimicrobial agents are described. By using quaternary surfactants with antimicrobial activity, the product can be formulated with antimicrobial properties, or its existing antimicrobial effect, if present due to other ingredients, can be enhanced.

[0082] Particularly preferred cationic surfactants, in addition to the quaternary ammonium compounds used as drying and gloss additives, are the quaternary ammonium compounds (QACs), some of which have antimicrobial properties; INCIQuaternary ammonium compounds) according to the general formula (RI< )(R II< )(R III< )(R IV< )N +< X, in which RI< to R IV< are identical or different C 1-22 alkyl groups, C 7-28 aralkyl groups, or heterocyclic groups, wherein two, or in the case of aromatic incorporation as in pyridine, even three groups together with the nitrogen atom form the heterocycle, for example a pyridinium or imidazolinium compound, and X -< are halide ions, sulfate ions, hydroxide ions, or similar anions. For optimal antimicrobial activity, preferably at least one of the groups has a chain length of 8 to 18, in particular 12 to 16, carbon atoms.

[0083] Quaternary ammonium compounds (QACs) can be prepared by reacting tertiary amines with alkylating agents such as methyl chloride, benzyl chloride, dimethyl sulfate, dodecyl bromide, and even ethylene oxide. The alkylation of tertiary amines with one long alkyl group and two methyl groups is particularly straightforward, and the quaternation of tertiary amines with two long groups and one methyl group can also be carried out under mild conditions using methyl chloride. Amines with three long alkyl groups or hydroxy-substituted alkyl groups are less reactive and are preferably quaternized with dimethyl sulfate.

[0084] Suitable QAVs include, for example, benzalkonium chloride (N-alkyl-N,N-dimethyl-benzyl-ammonium chloride, CAS No. 8001-54-5), benzalkone B ( m,p-Dichlorbenzyl-dimethyl-C 12 -alkylammoniumchlorid, CAS No. 58390-78-6), Benzoxoniumchlorid (Benzyl-dodecyl-bis-(2-hydroxyethyl)-ammoniumchlorid), Cetrimoniumbromid (N-Hexadecyl-N,N-trimethyl-ammoniumbromid, CAS No. 57-09-0), Benzetoniumchlorid (N,N-Dimethyl-N-[2-[2[p- (1,1,3,3-tetramethylbutyl)phenoxy]ethoxy]ethyl]-benzylammoniumchlorid,CAS No.121-54-0), Dialkyldimethylammoniumchloride wie Di-n-decyldimethylammoniumchlorid (CAS No. 7173-51-5-5), Didecyldimethylammoniumbromid (CAS No. 2390-68-3), Dioctyldimethylammoniumchloric, 1-Cetylpyridiniumchlorid (CAS No. 123-03-5) und Thiazolinjodid (CAS No. 15764-48-1) sowie deren Mischungen.

Eine besonders bevorzugte QAV Kokospentaethoxymethylammoniummethosulfat (INCI PEG-5 Cocomonium Methosulfate; Rewoquat ®< CPEM).

[0085] To avoid potential incompatibilities between the antimicrobial cationic surfactants and the anionic surfactants contained in the invention, surfactants that are compatible with anionic surfactants and / or have as little cationic activity as possible are used, or, in a particular embodiment of the invention, antimicrobial cationic surfactants are omitted entirely. Parabens, benzoic acid and / or benzoate, lactic acid and / or lactates can be used as antimicrobial substances. Benzoic acid and / or lactic acid are particularly preferred.

[0086] The composition particularly favorably contains salts of alkyl ether sulfates, alkyl betaines and alkylamine oxides.

[0087] The composition may further comprise at least one solvent, thickener, and / or salts. The composition may be liquid. In particular, if it is a cleaning agent for the manual cleaning of dishes, it is liquid and also transparent. In this case, the natural material and the composition itself differ in color, resulting in a transparent liquid in which whitish or opaque particles are uniformly dispersed. To ensure a uniform distribution of the natural material within the composition, it preferably has a yield point. A yield point can be achieved through the use of thickeners, especially polymeric thickeners, and / or salts.If the composition is liquid, it exhibits a yield stress, particularly at low to medium shear, meaning that the storage modulus G' of the system is greater than the loss modulus G at shear rates of 0.0001 to 0.1 s -1<.

[0088] In rheology, the yield stress is defined as the shear stress (in Pa) below which a sample deforms exclusively or at least largely elastically, and above which irreversible plastic deformation, i.e., yielding, occurs. This yield stress is typically determined by measurement with a rheometer at room temperature, i.e., a temperature of 20 °C to 25 °C, particularly at 25 °C. Absolute rheometers, such as the AR 1000-N from Texas Instruments, enable the determination of reliable, absolute measurements independent of the measurement geometry.

[0089] According to the invention, the yield strength of the liquid, surfactant-containing composition can also be measured, for example, using a rotational rheometer from TA-Instruments, type AR G2 (shear stress-controlled rheometer, cone-plate measuring system with a 40 mm diameter, 2° cone angle, 20°C). This is a so-called shear stress-controlled rheometer. Here, the samples are subjected to a shear stress that increases over time within the rheometer. σ (t) is applied. For example, the shear stress can be increased from the smallest possible value (e.g., 0.01 Pa) to, for example, 100 Pa over the course of 30 minutes. The deformation is calculated as a function of this shear stress σ. γ The deformation is measured in a double-logarithmic plot against the shear stress (log γ against log σIf the sample under investigation has a yield strength, this can be identified by a sudden change in the curve. Below a certain shear stress, purely elastic deformation occurs. The slope of the curve γ ( σ The shear stress in the log-log plot is one in this region. Above this shear stress, viscous flow begins, and the slope of the curve increases sharply. The shear stress at which the curve buckles, i.e., the transition from elastic to plastic deformation, marks the yield point. The yield point (the point where the curve buckles) can be conveniently determined by drawing tangents to the two curve segments. Specimens without a yield point do not exhibit a characteristic buckle in their function. γ ( σ ) on.

[0090] The composition according to the invention preferably has a yield strength in the range of 0.01 Pa to 10 Pa, preferably from 0.1 Pa to 5 Pa, and particularly preferably from 0.5 Pa to 3 Pa.

[0091] Correspondingly fluid compositions with a yield point are sufficiently described in the prior art.

[0093] In a preferred embodiment, the hand dishwashing liquid according to the invention further contains one or more water-soluble salts to reduce viscosity. These can be inorganic and / or organic salts; in a preferred embodiment, the liquid contains at least one inorganic salt.

[0094] Inorganic salts that can be used according to the invention are preferably selected from the group comprising colorless, water-soluble halides, sulfates, sulfites, carbonates, hydrogen carbonates, nitrates, nitrites, phosphates, and / or oxides of the alkali metals, alkaline earth metals, aluminum, and / or transition metals; ammonium salts can also be used. Halides and sulfates of the alkali metals are particularly preferred; therefore, the inorganic salt is preferably selected from the group comprising sodium chloride, potassium chloride, sodium sulfate, potassium sulfate, and mixtures thereof.

[0095] The organic salts that can be used according to the invention are in particular colorless, water-soluble alkali metal, alkaline earth metal, ammonium, aluminum, and / or transition metal salts of carboxylic acids. Preferably, the salts are selected from the group comprising formate, acetate, propionate, citrate, malate, tartrate, succinate, malonate, oxalate, lactate, and mixtures thereof.

[0096] The hand dishwashing liquid according to the invention contains, in a preferred embodiment, 0.1 to 10 wt.%, preferably 0.5 to 7 wt.%, and particularly preferably 0.8 to 5 wt.% of at least one water-soluble salt. In a particularly preferred embodiment, only inorganic salts are used.

[0097] Thickening agents according to the present invention are polycarboxylates, preferably homo- and copolymers of acrylic acid, in particular acrylic acid copolymers such as acrylic acid-methacrylic acid copolymers, and polysaccharides, in particular heteropolysaccharides, as well as other conventional polymeric thickeners. Layered silicates and other inorganic substances known to those skilled in the art as thickening agents can also be used as thickening agents according to this invention; mixtures of different thickening agents can also be used. It is only necessary to ensure that the largely transparent optical appearance is maintained when using the thickening agent. Preferably, however, polymers, especially polycarboxylates and / or polysaccharides, are used as thickening agents in cleaning agents according to the invention.

[0098] Suitable polysaccharides or heteropolysaccharides include polysaccharide gums, such as gum arabic, agar, alginates, carrageenan and its salts, guar, guaranine, tragacanth, gellan gum, ramsan, dextran, or xanthan gum and their derivatives, for example, propoxylated guar gum, as well as their mixtures. Other polysaccharide thickeners, such as starches or cellulose derivatives, can be used alternatively, but preferably in addition to a polysaccharide gum. Examples include starches of various origins and starch derivatives, such as hydroxyethyl starch, starch phosphate esters, or starch acetates, or carboxymethylcellulose or its sodium salt, methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, or hydroxyethylmethylcellulose, or cellulose acetate.

[0099] A preferred polymer is the microbial anionic heteropolysaccharide xanthan gum, which is produced by Xanthomonas campestris and some other species under aerobic conditions with a molecular weight of 2 to 15 × 10⁶ and is marketed, for example, by Kelco under the trade names Keltrof ®< and Kelzan ®< or also from the company Rhodia under the trade name Rhodopol ®< is available.

[0100] Another preferred polymer is the also microbial heteropolysaccharide gellan gum, which is produced under aerobic conditions, for example by Auromonas elodea and especially from Sphingonas paucimobilis- It is formed from strains. Gellan gum, for example, can be sold under the trade name Kelcogel ®< in various qualities from the company Kelco can be obtained.

[0101] Suitable acrylic acid polymers include, for example, high-molecular-weight homopolymers of acrylic acid cross-linked with a polyalkenyl polyether, in particular an allyl ether of sucrose, pentaerythritol or propylene. (INCI Carbomer), which are also known as carboxyvinyl polymers. Such polyacrylic acids are produced, among others, by the company... BFGoodrich under the trade name Carbopof ®< available.

[0102] Particularly suitable polymers are the following acrylic acid copolymers: (i) copolymers of two or more monomers from the group consisting of acrylic acid, methacrylic acid and their simple esters, preferably formed with C1-4 alkanols (INCI Acrylates copolymer), which include copolymers of methacrylic acid, butyl acrylate and methyl methacrylate (CAS 25035-69-2) or of butyl acrylate and methyl methacrylate (CAS 25852-37-3) and which are manufactured, for example, by the company. Rohm & Haas under the trade names Aculyn ®< and Acusol®< and from the company Degussa (Goldschmidt) under the trade name Tego ®< polymer are available; (ii) crosslinked high-molecular-weight acrylic acid copolymers, including, for example, copolymers of C 10-30 alkyl acrylates crosslinked with an allyl ether of sucrose or pentaerythritol with one or more monomers from the group consisting of acrylic acid, methacrylic acid and their simple esters, preferably formed with C 14 alkanols (INCI Acrylates / C10-30 Alkyl Acrylate Crosspolymer) and are, for example, those manufactured by the company. BFGoodrich under the trade name Carbopol Suitable acrylic acid esters are also available from BASF under the trade names Skalan® AT 120 and Rheovis® AT 120. When acrylic acid polymers, and in particular acrylic acid esters, are used as polymeric thickeners, the pH value is preferably greater than 7, particularly at least 7.5, and preferably 8 or more.

[0103] Layered silicates are particularly suitable as inorganic thickening agents. These include, for example, those sold under the trade name... Laponites ®< available magnesium or sodium-magnesium layered silicates from the company Solvay Alkali, especially the Laponites ®< RD or Laponites ®< RDS, as well as the magnesium silicates of the company Süd-Chemie, especially that Optigel ®< SH.

[0104] The selection of the thickening agent is always made with the requirement that the largely transparent optical appearance be maintained; that is, clouding caused by the thickening agent should be largely avoided. The thickening agent content is typically between 0.01 and 8 wt.%, preferably between 0.1 and 6 wt.%, and particularly preferably between 0.5 and 3 wt.%, for example between 0.5 and 1 wt.% or between 2 and 3 wt.%. The viscosity of the compositions according to the invention is essentially adjusted or controlled by the thickening agent content, whereby the required amounts can vary from thickener to thickener. The surfactant composition used also plays a role in the selection of the quantity.

[0105] Depending on the thickening agent used, it may be desirable to additionally use electrolyte salts for stabilization. Electrolyte salts within the meaning of this invention are salts of preferably polyvalent cations with inorganic acid residues. Particularly preferred are the chlorides and sulfates of the alkaline earth metals, aluminum, and zinc, especially aluminum chloride. The use of these electrolyte salts is particularly advantageous in combination with polysaccharide thickening agents such as xanthan gum or gellan gum.

[0106] However, it is also possible that the composition is solid, for example, pasty. In such a case, a yield point is not necessarily required.

[0107] Preferably, the composition, when liquid, comprises water as a solvent, the proportion of which is particularly 1 wt.% to 99 wt.%, preferably 95 wt.% or less, particularly 90 wt.% or less, and preferably 5 wt.% or 10 wt.% or more. Furthermore, a liquid composition may also contain other solvents, such as short-chain alcohols. In addition, it typically contains one or more auxiliary or additive substances, as are well described in the prior art. These are preferably selected from enzymes, UV stabilizers, perfumes, dyes, polymers, cleaning boosters, disinfectants, antistatic agents, corrosion inhibitors, preservatives, skin protectants, and mixtures thereof.
