Hair coloring agent containing a film-forming, hydrophilic polymer

Description

[0001] The present application relates to an agent for coloring keratinic material, in particular human hair, which contains in a cosmetic carrier (a) at least one specific organic silicon compound of formula (I), (b) at least one coloring compound from the group of pigments and (c) at least one film-forming, hydrophilic polymer selected from the group of polyvinylpyrrolidone (PVP) and the copolymers of polyvinylpyrrolidone.

[0002] This application further relates to a multi-component packaging unit (kit of parts) for coloring keratinous material, in particular human hair, which comprises agents (I), (II), and (III) packaged separately in three different containers. Agent (I) contains at least one organic silicon compound (a) of formula (I), agent (II) contains water, and agent (III) contains at least one colorant compound from the group of pigments (b) and at least one film-forming, hydrophilic polymer (c) selected from the group consisting of polyvinylpyrrolidone (PVP) and copolymers of polyvinylpyrrolidone.

[0003] A third subject matter of the present application is a process for coloring keratinous material, which comprises the application of a pretreatment agent (V) followed by the application of a colorant (F). The pretreatment agent (V) contains at least one specific organic silicon compound (a) of formula (I) in an aqueous cosmetic carrier. The colorant (F) is characterized by its content of at least one colorant compound from the group of pigments (b) and at least one film-forming, hydrophilic polymer (c) selected from the group of polyvinylpyrrolidone (PVP) and copolymers of polyvinylpyrrolidone.

[0004] Altering the shape and color of keratin fibers, especially hair, represents an important area of ​​modern cosmetics. Depending on the coloring requirements, hair coloring experts are familiar with various coloring systems. For permanent, intense colorings with good fastness properties and good gray coverage, oxidation dyes are typically used. Such dyes typically contain oxidation dye precursors, so-called developer components, and coupler components, which, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes. Oxidation dyes are characterized by very long-lasting coloring results.

[0005] When using direct dyes, the fully formed pigments diffuse from the dyeing agent into the hair fiber. Compared to oxidative hair coloring, the colors obtained with direct dyes are less durable and wash out more quickly. Colorations with direct dyes typically remain on the hair for between 5 and 20 washes.

[0006] DE 10200195 A1 describes a semi-permanent hair dye or hair tinting composition containing a direct dye, a hydrocarbon oil and a polyalkoxylene-modified dimethylpolysiloxane.

[0007] EP 1532967 A1 addresses agents and methods for styling and caring for hairstyles, which contain at least one gellan gum or a derivative thereof, 0.001 to 5 wt.% of at least one solid component and at least one monovalent salt.

[0008] The use of color pigments is known for temporary color changes on hair and / or skin. Color pigments are generally understood to be insoluble, color-imparting substances. These are present undissolved in the form of small particles in the coloring formulation and are deposited only externally on the hair fibers and / or the skin surface. Therefore, they can usually be removed without residue after several washes with surfactant-containing cleansers. Various products of this type are available on the market under the name hair mascara.

[0009] If the user desires particularly long-lasting color results, the use of oxidative colorants has so far been the only option. However, despite numerous optimization attempts, an unpleasant ammonia or amine odor cannot be completely eliminated with oxidative hair coloring. The hair damage still associated with the use of oxidative colorants also has a detrimental effect on the user's hair.

[0010] EP 2168633 B1 addresses the problem of creating long-lasting hair colorings using pigments. The document teaches that using a combination of pigment, organic silicon compound, hydrophobic polymer, and a solvent, it is possible to create hair colorings that are particularly resistant to shampooing.

[0011] In reworking the teaching of EP 2168633 B1, the formulations were recreated. This revealed that one disadvantage of these formulations is their poor storage stability. The pigments and hydrophobic polymers contained in the formulations are very poorly soluble substances. While these could be dispersed briefly during preparation, they conglomerated, settled, or separated from the aqueous phase over longer storage periods. Depending on the chosen concentration of pigment and hydrophobic polymer, it has also proven difficult to achieve sufficiently fine dispersion of the poorly soluble substances during production.

[0012] The object of the present invention was to provide a dyeing system that possesses fastness properties comparable to oxidative dyeing. In particular, the washfastness properties should be outstanding, while avoiding the use of the oxidation dye precursors typically used for this purpose. The aim was to find a technology that would enable the coloring compounds known from the prior art (such as pigments and direct dyes) to be fixed to the hair in an extremely permanent manner. This required ensuring sufficiently high storage stability of the formulations. Furthermore, the production process for the formulations should also be simplified or optimized.

[0013] Surprisingly, it has now been found that the above-mentioned object can be excellently achieved if keratinic materials, in particular human hair, are colored with an agent which contains, in a cosmetic carrier, at least one specific organic silicon compound, at least one color-imparting compound from the group of pigments and at least one film-forming, hydrophilic polymer selected from the group of polyvinylpyrrolidone (PVP) and the copolymers of polyvinylpyrrolidone.

[0014] A first subject of the present invention is therefore an agent for coloring keratinic material, in particular human hair, containing in a cosmetic carrier (a) at least one organic silicon compound of the formula (I), R 1 R 2 NL-Si(OR 3 ) a (R 4 ) b (I), where R 1 , R 2 both represent a hydrogen atom, and L represents a linear, divalent C 1 -C 6 alkylene group, R 3 represents a hydrogen atom or a C 1 -C 6 alkyl group, R 4 represents a C 1 -C 6 alkyl group, a represents an integer from 1 to 3, and b represents the integer 3 - a, and, (b) at least one color-providing compound from the group of pigments, and (c) at least one film-forming, hydrophilic polymer selected from the group of polyvinylpyrrolidone (PVP) and the copolymers of polyvinylpyrrolidone.

[0015] In the course of the work leading to this invention, it was found that the incorporation of the inventive organic silicon compounds (a), the coloring compounds (b), and the film-forming, hydrophilic polymers (c) into a cosmetic carrier resulted in formulations with excellent storage stability. Without being limited to this theory, it is assumed in this context that the readily soluble, film-forming polymers (c) keep the coloring compounds in dispersion or prevent them from settling or separating. The preparation of the formulations was also simplified because the hydrophilic polymers were very easy to dissolve due to their good water solubility. It proved particularly advantageous that particularly stable formulations could be produced in this way even without the use of large amounts of surfactants.

[0016] Surprisingly, it was further discovered that despite the use of a hydrophilic, i.e., highly water-soluble polymer (c) together with the other ingredients (a) and (b), a very resistant film could be created on the keratin material. Therefore, extremely washfast colorations with good resistance to shampooing were obtained on the keratin material. Agents for coloring keratin material

[0017] Keratinous material includes hair, skin, and nails (such as fingernails and / or toenails). Wool, fur, and feathers also fall under the definition of keratinous material.

[0018] Keratin material is preferably understood to mean human hair, human skin, and human nails, especially fingernails and toenails. Keratin material is most preferably understood to mean human hair.

[0019] The compositions according to the invention contain the compounds (a), (b), and (c) essential to the invention in a cosmetic carrier, preferably a suitable aqueous or aqueous-alcoholic carrier. For the purpose of hair coloring, such carriers include, for example, creams, emulsions, gels, or surfactant-containing foaming solutions, such as shampoos, foam aerosols, foam formulations, or other preparations suitable for application to the hair.

[0020] The cosmetic carrier is preferably water-containing, which means that the carrier contains at least 2% by weight of water, based on its weight. The water content is preferably above 5% by weight, more preferably above 10% by weight, even more preferably above 15% by weight. The cosmetic carrier can also be aqueous-alcoholic. For the purposes of the present invention, aqueous-alcoholic solutions are understood to mean aqueous solutions containing 2 to 70% by weight of a C 1 -C 4 alcohol, in particular ethanol or isopropanol. The agents according to the invention can additionally contain other organic solvents, such as, for example, methoxybutanol, benzyl alcohol, ethyl diglycol or 1,2-propylene glycol. Preference is given to all water-soluble organic solvents.

[0021] The term "coloring agent" is used in the context of this invention for the coloring of keratin material, particularly hair, caused by the use of pigments. During this coloring, the aforementioned coloring compounds are deposited in a particularly homogeneous and smooth film on the surface of the keratin material or diffuse into the keratin fiber. The film forms in situ through oligomerization or polymerization of the organic silicon compound(s), and through the interaction of the coloring compound and the organic silicon compound with the film-forming, hydrophilic polymer. Organic silicon compounds

[0022] As the first component (a) essential to the invention, the agents according to the invention contain at least one organic silicon compound of the formula (I).

[0023] Organic silicon compounds, alternatively also called organosilicon compounds, are compounds that either have a direct silicon-carbon bond (Si-C) or in which the carbon is linked to the silicon atom via an oxygen, nitrogen or sulfur atom.

[0024] The substituents R 1 , R 2 , R 3 , R 4 , L in the compounds of formula (I) are exemplified below: Examples of a C 1 -C 6 alkyl group are the groups methyl, ethyl, propyl, isopropyl, n-butyl, s-butyl and t-butyl, n-pentyl and n-hexyl. Propyl, ethyl and methyl are preferred alkyl radicals. Examples of a linear divalent C 1 -C 20 alkylene group are, for example, the methylene group (-CH 2 -), the ethylene group (-CH 2 -CH 2 -), the propylene group (-CH 2 -CH 2 -CH 2 -) and the butylene group (-CH 2 -CH 2 -CH 2 -CH 2 -). The propylene group (-CH 2 -CH 2 -CH 2 -) is particularly preferred. From a chain length of 3 carbon atoms, divalent alkylene groups can also be branched. Examples of branched, divalent C 3 -C 20 alkylene groups are (-CH 2 -CH(CH 3 )-) and (-CH 2 -CH(CH 3 )-CH 2 -).

[0025] In the organic silicon compounds of the formula (I) R 1 R 2 NL-Si(OR 3 ) a (R 4 ) b (I), the radicals R 1 and R 2 represent a hydrogen atom

[0026] In the middle part of the organic silicon compound is the structural unit or linker -L-, which represents a linear divalent C 1 -C 6 alkylene group. Particularly preferably, -L- represents a methylene group (-CH 2 -), an ethylene group (-CH 2 -CH 2 -), a propylene group (-CH 2 -CH 2 -CH 2 -), or a butylene group (-CH 2 -CH 2 -CH 2 -CH 2 -). Most preferably, L represents a propylene group (-CH 2 -CH 2 -CH 2 -).

[0028] The organic silicon compounds of the formula (I) R 1 R 2 NL-Si(OR 3 ) a (R 4 ) b (I) according to the invention each carry the silicon-containing group -Si(OR 3 ) a (R 4 ) b at one end.

[0029] In the terminal structural unit -Si(OR 3 ) a (R 4 ) b, the radical R 3 represents a hydrogen atom or a C 1 -C 6 alkyl group, and the radical R 4 represents a C 1 -C 6 alkyl group. Particularly preferably, R 3 and R 4 independently represent a methyl group or an ethyl group.

[0030] Here, a represents an integer from 1 to 3, and b represents the integer 3 - a. If a represents the number 3, then b is 0. If a represents the number 2, then b is 1. If a represents the number 1, then b is 2.

[0031] Dyes with the best wash fastness properties could be obtained if the agent according to the invention contains at least one organic silicon compound of the formula (I) in which the radicals R 3 , R 4 independently of one another represent a methyl group or an ethyl group.

[0032] Furthermore, dyeings with the best washfastness properties could be obtained when the agent according to the invention contains at least one organic silicon compound of formula (I) in which the radical a represents the number 3. In this case, the radical b represents the number 0.

[0036] The aforementioned organic silicon compounds of formula (I) are commercially available. (3-Aminopropyl)trimethoxysilane, for example, can be purchased from Sigma-Aldrich. (3-Aminopropyl)triethoxysilane is also commercially available from Sigma-Aldrich.

[0037] The organic silicon compounds of formula (I) are reactive compounds. In this context, it has been found to be preferred if the agent according to the invention contains—based on its total weight—one or more organic silicon compounds (a) in a total amount of 0.1 to 20.0 wt.%, preferably 0.2 to 15.0 wt.%, and particularly preferably 0.2 to 2.0 wt.%.

[0038] In this context, it has been found to be particularly preferred if the agent according to the invention - based on its total weight - contains one or more organic silicon compounds (a) of the formula (I) in a total amount of 0.1 to 20.0 wt.%, preferably 0.2 to 15.0 wt.% and particularly preferably 0.2 to 2.0 wt.%.

The water solubility can be determined, for example, using the method described below: 0.5 g of the pigment is weighed into a beaker. A stirring bar is added. Then, one liter of distilled water is added. This mixture is heated to 25°C for one hour while stirring on a magnetic stirrer. If undissolved components of the pigment are still visible in the mixture after this period, the solubility of the pigment is below 0.5 g / L. If the pigment-water mixture cannot be visually assessed due to the high intensity of the pigment, which may be present in finely dispersed form, the mixture is filtered.If a portion of undissolved pigment remains on the filter paper, the solubility of the pigment is below 0.5 g / L.

[0041] Suitable color pigments can be of inorganic and / or organic origin.

[0042] In a preferred embodiment, an agent according to the invention is characterized in that it contains (b) at least one color-providing compound from the group of inorganic and / or organic pigments.

[0043] Preferred color pigments are selected from synthetic or natural inorganic pigments. Inorganic color pigments of natural origin can be made from chalk, ochre, umber, green earth, burnt sienna, or graphite, for example. Other inorganic color pigments that can be used include black pigments such as iron oxide black, colored pigments such as ultramarine or iron oxide red, as well as fluorescent or phosphorescent pigments.

[0045] Also particularly preferred color pigments according to the invention are colored pearlescent pigments. These are typically based on mica and / or mica and can be coated with one or more metal oxides. Mica belongs to the class of layered silicates. The most important representatives of these silicates are muscovite, phlogopite, paragonite, biotite, lepidolite, and margarite. To produce pearlescent pigments in combination with metal oxides, the mica, predominantly muscovite or phlogopite, is coated with a metal oxide.

[0046] As an alternative to natural mica, synthetic mica, optionally coated with one or more metal oxides, can also be used as a pearlescent pigment. Particularly preferred pearlescent pigments are based on natural or synthetic mica and coated with one or more of the aforementioned metal oxides.

[0053] In a further embodiment, the agent according to the invention may also contain (b) one or more coloring compounds from the group of organic pigments

[0054] The organic pigments according to the invention are correspondingly insoluble, organic dyes or lakes which can be selected, for example, from the group of nitroso, nitro, azo, xanthene, anthraquinone, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyorrole, indigo, thioindido, dioxazine and / or triarylmethane compounds.

[0055] Particularly suitable organic pigments are, for example, carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, orange pigments with the color index numbers CI 11725, CI 15510, CI 45370, CI 71105, red pigments with the Color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0056] In a further particularly preferred embodiment, a composition according to the invention is characterized in that it contains (b) at least one color-providing compound from the group of organic pigments, which is selected from the group of carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, orange pigments with the color index numbers CI 11725, CI 15510, CI 45370, CI 71105, red pigments with the color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0057] The organic pigment can also be a colored lake. For the purposes of the invention, the term colored lake refers to particles comprising a layer of absorbed dyes, the particle-dye unit being insoluble under the aforementioned conditions. The particles can be, for example, inorganic substrates, which can be aluminum, silica, calcium borosilicate, calcium aluminum borosilicate, or even aluminum.

[0058] Alizarin lake, for example, can be used as a colored varnish.

[0059] Due to their excellent light and temperature resistance, the use of the aforementioned pigments in the agents according to the invention is particularly preferred. Furthermore, it is preferred if the pigments used have a specific particle size. This particle size leads, on the one hand, to a uniform distribution of the pigments in the formed polymer film and, on the other hand, avoids a rough feeling in the hair or skin after application of the cosmetic agent. It is therefore advantageous according to the invention if the at least one pigment has an average particle size D 50 of 1.0 to 50 µm, preferably from 5.0 to 45 µm, more preferably from 10 to 40 µm, in particular from 14 to 30 µm. The average particle size D 50 can be determined, for example, using dynamic light scattering (DLS).

[0060] The pigment(s) (b) can be used in an amount of 0.001 to 20% by weight, in particular 0.05 to 5% by weight, in each case based on the total weight of the agent according to the invention.

[0061] Direct dyes have a solubility in water (760 mmHg) at 25 °C of more than 0.5 g / L and are therefore not considered pigments. film-forming, hydrophilic polymer

[0062] As the third ingredient (c) essential to the invention, the agents according to the invention contain at least one film-forming, hydrophilic polymer selected from the group consisting of polyvinylpyrrolidone (PVP) and the copolymers of polyvinylpyrrolidone.

[0063] Polymers are understood to be macromolecules with a molecular weight of at least 1000 g / mol, preferably at least 2500 g / mol, particularly preferably at least 5000 g / mol, which consist of identical, repeating organic units. The polymers of the present invention can be synthetically produced polymers prepared by polymerizing one monomer type or by polymerizing different, structurally different monomer types. If the polymer is prepared by polymerizing one monomer type, it is referred to as a homopolymer. If structurally different monomer types are used in the polymerization, the resulting polymer is referred to as a copolymer.

[0064] The maximum molecular weight of the polymer depends on the degree of polymerization (number of polymerized monomers) and the batch size, and is also determined by the polymerization method. For the purposes of the present invention, it is preferred if the maximum molecular weight of the film-forming, hydrophobic polymer (c) is not more than 10 7 g / mol, preferably not more than 10 6 g / mol, and particularly preferably not more than 10 5 g / mol.

[0065] A hydrophilic polymer is understood to be a polymer that has a solubility in water at 25 °C (760 mmHg) of more than 1 wt.%, preferably more than 2 wt.%.

[0066] The water solubility of a film-forming, hydrophilic polymer can be determined, for example, as follows: 1.0 g of the polymer is placed in a beaker. The volume is made up to 100 g with water. A stir bar is added, and the mixture is heated to 25 °C on a magnetic stirrer while stirring. Stirring is continued for 60 minutes. The aqueous mixture is then visually assessed. A completely dissolved polymer appears homogeneous microscopically. If the polymer-water mixture cannot be assessed visually due to high turbidity, the mixture is filtered. If no undissolved polymer remains on the filter paper, the polymer's solubility is greater than 1 wt.%.

[0067] For the purposes of the invention, a film-forming polymer is understood to be a polymer capable of forming a film on a substrate, for example, on a keratin material or a keratin fiber. The formation of a film can be demonstrated, for example, by observing the keratin material treated with the polymer under a microscope.

[0068] Non-ionic, anionic and cationic polymers can be used as film-forming, hydrophilic polymers.

[0069] Suitable film-forming, hydrophilic polymers are selected from the group of polyvinylpyrrolidone (co)polymers.

[0070] Polyvinylpyrrolidone, a film-forming, hydrophilic polymer (c), dissolved very easily in water and kept even large amounts of pigments stable in dispersion for extended periods. Surprisingly, the washfastness of the dyes obtained with PVP-containing formulations was also very good.

[0071] Particularly suitable polyvinylpyrrolidones are available, for example, under the name Luviskol ®< K from BASF SE, in particular Luviskol ®< K 90 or Luviskol ®< K 85 from BASF SE.

[0072] Another particularly suitable polyvinylpyrrolidone (PVP) is the polymer PVP K30, which is marketed by Ashland (ISP, POI Chemical). PVP K 30 is a polyvinylpyrrolidone that is highly soluble in cold water and has the CAS number 9003-39-8. The molecular weight of PVP K 30 is approximately 40,000 g / mol.

[0073] Other particularly suitable polyvinylpyrrolidones are the substances known under the trade names LUVITEC K 17, LUVITEC K 30, LUVITEC K 60, LUVITEC K 80, LUVITEC K 85, LUVITEC K 90 and LUVITEC K 115 and available from BASF.

[0074] The use of film-forming hydrophilic polymers (c) from the group of polyvinylpyrrolidone copolymers also led to particularly good and washfast color results. The storage stability of formulations containing one or more polyvinylpyrrolidone copolymers (c) was also very good.

[0075] Particularly suitable film-forming, hydrophilic polymers in this context are vinylpyrrolidone-vinyl ester copolymers, such as those sold under the trademark Luviskol ® (BASF). Luviskol ® VA 64 and Luviskol ® VA 73, each vinylpyrrolidone / vinyl acetate copolymers, are particularly preferred nonionic polymers.

[0076] Of the vinylpyrrolidone-containing copolymers, a styrene / VP copolymer and / or a vinylpyrrolidone-vinyl acetate copolymer and / or a VP / DMAPA acrylates copolymer and / or a VP / vinyl caprolactam / DMAPA acrylates copolymer are very particularly preferably used in the cosmetic compositions.

[0077] Vinylpyrrolidone-vinyl acetate copolymers are marketed under the name Luviskol®< VA by BASF SE. A VP / Vinyl Caprolactam / DMAPA Acrylates copolymer, for example, is marketed under the trade name Aquaflex®< SF-40 by Ashland Inc. A VP / DMAPA Acrylates copolymer, for example, is marketed under the name Styleze CC-10 by Ashland and is a highly preferred vinylpyrrolidone-containing copolymer.

[0078] Other suitable copolymers of polyvinylpyrrolidone (c) which may also be mentioned are the copolymers obtained by reacting N-vinylpyrrolidone with at least one further monomer from the group consisting of N-vinylformamide, vinyl acetate, ethylene, propylene, acrylamide, vinylcaprolactam, vinylcaprolactone and / or vinyl alcohol.

[0079] In a further very particularly preferred embodiment, an agent according to the invention is characterized in that it contains (c) at least one film-forming, hydrophilic polymer which is selected from the group consisting of polyvinylpyrrolidone (PVP), vinylpyrrolidone / vinyl acetate copolymers, vinylpyrrolidone / styrene copolymers, vinylpyrrolidone / ethylene copolymers, vinylpyrrolidone / propylene copolymers, vinylpyrrolidone / vinylcaprolactam copolymers, vinylpyrrolidone / vinylformamide copolymers and / or vinylpyrrolidone / vinyl alcohol copolymers.

[0080] Another suitable copolymer of vinylpyrrolidone is the polymer known under the INCI name Maltodextrin / VP Copolymer.

[0081] Furthermore, intensively colored keratin material, especially hair, with very good wash fastness could be obtained when a non-ionic, film-forming, hydrophilic polymer was used as the film-forming, hydrophilic polymer.

[0082] In a particularly preferred embodiment, an agent according to the invention is characterized in that it contains (c) at least one non-ionic, film-forming, hydrophilic polymer.

[0083] For the purposes of the invention, a nonionic polymer is defined as a polymer that, in a protic solvent—such as water—under standard conditions, does not contain structural units with permanently cationic or anionic groups that must be compensated by counterions while maintaining electroneutrality. Cationic groups include, for example, quaternized ammonium groups but not protonated amines. Anionic groups include, for example, carboxyl and sulfonic acid groups.

[0084] The agents are particularly preferred which contain as non-ionic, film-forming, hydrophilic polymer at least one polymer selected from the group consisting of Polyvinylpyrrolidone, copolymers of N-vinylpyrrolidone and vinyl esters of carboxylic acids having 2 to 18 carbon atoms, in particular of N-vinylpyrrolidone and vinyl acetate, copolymers of N-vinylpyrrolidone and N-vinylimidazole and methacrylamide, copolymers of N-vinylpyrrolidone and N-vinylimidazole and acrylamide, copolymers of N-vinylpyrrolidone with N,N-di(C 1 to C 4 )-alkylamino-(C 2 to C 4 )-alkylacrylamide.

[0085] If copolymers of N-vinylpyrrolidone and vinyl acetate are used, it is again preferred if the molar ratio of the structural units contained in the monomer N-vinylpyrrolidone to the structural units of the polymer contained in the monomer vinyl acetate is in the range from 20 to 80 to 80 to 20, in particular from 30 to 70 to 60 to 40. Suitable copolymers of vinylpyrrolidone and vinyl acetate are available, for example, under the trademarks Luviskol®< VA 37, Luviskol®< VA 55, Luviskol®< VA 64 and Luviskol®< VA 73 from BASF SE.

[0086] Another particularly preferred polymer is selected from the polymers with the INCI name VP / Methacrylamide / Vinyl Imidazole Copolymer, which are available, for example, under the trade name Luviset Clear from BASF SE.

[0087] Another particularly preferred non-ionic, film-forming, hydrophilic polymer is a copolymer of N-vinylpyrrolidone and N,N-dimethylaminopropylmethacrylamide, which is sold, for example, with the INCI name VP / DMAPA Acrylates Copolymer, e.g., under the trade name Styleze®< CC 10 by the company ISP.

[0088] A cationic polymer according to the invention is the copolymer of N-vinylpyrrolidone, N-vinylcaprolactam, N-(3-dimethylaminopropyl)methacrylamide and 3-(methacryloylamino)propyl-lauryl-dimethylammonium chloride (INCI name: Polyquaternium-69), which is marketed, for example, under the trade name AquaStyle ®< 300 (28-32 wt.% active substance in ethanol-water mixture, molecular weight 350,000) by the company ISP.

[0089] Other suitable film-forming, hydrophilic polymers are, for example, Vinylpyrrolidone-vinylimidazolium methochloride copolymers, as sold under the names Luviquat ®< FC 370, FC 550 and the INCI name Polyquaternium-16 as well as FC 905 and HM 552, vinylpyrrolidone-vinylcaprolactam-acrylate terpolymers, as sold with acrylic acid esters and acrylic acid amides as the third monomer building block, for example under the name Aquaflex ®< SF 40.

[0090] Polyquaternium-11 is the reaction product of diethyl sulfate with a copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate. Suitable commercial products are available, for example, under the names Dehyquart®< CC 11 and Luviquat®< PQ 11 PN from BASF SE or Gafquat 440, Gafquat 734, Gafquat 755, or Gafquat 755N from Ashland Inc.

[0091] Polyquaternium-46 is the reaction product of vinylcaprolactam and vinylpyrrolidone with methylvinylimidazolium methosulfate and is available, for example, under the name Luviquat® Hold from BASF SE. Polyquaternium-46 is preferably used in an amount of 1 to 5 wt.%, based on the total weight of the cosmetic composition. It is particularly preferred that Polyquaternium-46 be used in combination with a cationic guar compound. It is even more preferred that Polyquaternium-46 be used in combination with a cationic guar compound and Polyquaternium-11.

[0092] The film-forming hydrophilic polymer(s) (c) according to the invention are preferably used in specific quantity ranges in the agent according to the invention. In this context, it has proven particularly preferred for achieving the object of the invention if the agent contains—based on its total weight—one or more polymers in a total amount of 0.1 to 25.0 wt.%, preferably 0.2 to 20.0 wt.%, more preferably 0.5 to 15.0 wt.%, and most preferably 1.0 to 7.0 wt.%.

Water content of the products

[0094] The agent according to the invention contains the essential ingredients (a), (b) and (c) in a cosmetic carrier, preferably in an aqueous or water-containing cosmetic carrier.

[0095] Without being bound to this theory, it is assumed that the organic silicon compound (a), which comprises one or more hydroxyl groups or hydrolyzable groups per molecule, hydrolyzes and / or oligomerizes in the presence of water. The hydrolysis products or oligomers formed in this way have a particularly high affinity for the surface of the keatin material. In this way, a stable and resistant film can be formed with the color-providing compounds (b) together with the film-forming, hydrophilic polymer (c). In this context, it has proven particularly preferred if the agent - based on its total weight - has a water content of 15 to 95 wt.%, preferably 20 to 95 wt.%, more preferably 25 to 95 wt.%, even more preferably 30 to 95 wt.%, and most preferably 45 to 95 wt.%.

[0097] The above-described agent of the first subject matter of the invention is the ready-to-use colorant. This contains the organic silicon compound(s) (a), a class of reactive compounds that, as described above, can undergo hydrolysis and / or oligomerization in the presence of water.

[0098] To increase storage stability, this product is preferably provided to the user in the form of a multi-component packaging unit (kit of parts). Shortly before application to the keratin material, the user can mix the various components of this packaging unit to create the ready-to-use colorant.

[0099] A second subject of the present invention is a multi-component packaging unit (kit-of-parts) for coloring keratin material, in particular human hair, which is packaged separately from one another a first container containing a cosmetic agent (I) and a second container containing a cosmetic agent (II) and a third container containing a cosmetic agent (III), wherein the agent (I) contains at least one organic silicon compound (a), as already disclosed in detail in the description of the first subject matter of the invention, the agent (II) contains water and the agent (III) contains at least one color-providing compound from the group of pigments (b) and at least one film-forming, hydrophilic polymer (c), as already disclosed in detail in the description of the first subject matter of the invention.

[0101] For example, the user can first stir or shake the agent (I), which contains the organic silicon compound(s) (a), with the water-containing agent (II). The user can then add the agent (III), which contains the colorant(s) (b) and the film-forming, hydrophilic polymer(s) (c), to the mixture of (I) and (II) and mix all three agents together.

[0102] In a further particularly preferred embodiment, it is also possible to apply the agents (I), (II) and (III) successively to the keratin material, so that the agents only interact with each other on the keratin material.

[0103] For example, the user can first stir or shake the agent (I), which contains the organic silicon compound(s) (a), with the water-based agent (II). The user can then apply this mixture of (I) and (II) to the keratin materials—either directly after preparation or after a short reaction time of 10 seconds to 20 minutes. The user can then apply the agent (III), which contains the color-imparting compounds (b) and the film-forming, hydrophilic polymer (c), to the keratin material.

[0104] The agent (I) contains at least one organic silicon compound (a) of formula (I), as already disclosed in detail in the description of the first subject matter of the invention.

[0105] In order to provide a formulation that is as stable as possible during storage, the agent (I) itself is preferably formulated with little or no water.

[0110] In a particularly preferred embodiment, the agent (III) contains the already mentioned, the preferred and the particularly preferred film-forming, hydrophilic polymers (c).

[0111] Agents (I) and (II), or agents (I), (II), and (III), can be mixed together in various amounts. For example, the first container can contain 5 g to 200 g of agent (I). The second container can contain 5 g to 200 g of agent (II). The third container can contain 5 g to 200 g of agent (III). Other ingredients

[0112] The agents described above, ie the ready-to-use agent of the first subject matter of the invention, and also the agents (I), (II) and (III) of the kit according to the invention of the second subject matter of the invention, may further contain one or more optional ingredients.

[0113] The agents may also contain one or more surfactants. Surfactants are surface-active substances. A distinction is made between anionic surfactants consisting of a hydrophobic residue and a negatively charged hydrophilic head group; amphoteric surfactants, which carry both a negative and a compensating positive charge; cationic surfactants, which have a hydrophobic residue and a positively charged hydrophilic group; and nonionic surfactants, which have no charges but strong dipole moments and are highly hydrated in aqueous solution.

[0114] Zwitterionic surfactants are surface-active compounds that contain at least one quaternary ammonium group and at least one -COO(-)<- or -SO3(-)<- group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines such as N-alkyl-N,N-dimethylammonium glycinates, for example cocoalkyl dimethylammonium glycinate, N-acyl-aminopropyl-N,N-dimethylammonium glycinates, for example cocoacylaminopropyl dimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines, each with 8 to 18 C atoms in the alkyl or acyl group, as well as cocoacylaminoethyl hydroxyethylcarboxymethylglycinate. A preferred zwitterionic surfactant is the fatty acid amide derivative known under the INCI name Cocamidopropyl Betaine.

[0115] Ampholytic surfactants are surface-active compounds that, in addition to a C8-C24 alkyl or acyl group, contain at least one free amino group and at least one -COOH- or -SO3H- group in the molecule and are capable of forming internal salts. Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids, and alkylaminoacetic acids, each with approximately 8 to 24 carbon atoms in the alkyl group. Typical examples of amphoteric or zwitterionic surfactants are alkyl betaines, alkylamidobetaines, aminopropionates, aminoglycinates, imidazolinium betaines and sulfobetaines.

[0116] Particularly preferred ampholytic surfactants are N-cocoalkylaminopropionate, cocoacylaminoethylaminopropionate and C 12 - C 18 acylsarcosine.

[0117] The agents may also additionally contain at least one nonionic surfactant. Suitable nonionic surfactants are alkyl polyglycosides and alkylene oxide addition products with fatty alcohols and fatty acids, each containing 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid. Preparations with good properties are also obtained when they contain fatty acid esters of ethoxylated glycerin, which have been reacted with at least 2 moles of ethylene oxide, as nonionic surfactants. The nonionic surfactants are used in a total amount of 0.1 to 45% by weight, preferably 1 to 30% by weight, and most preferably 1 to 15% by weight, based on the total weight of the respective agent.

[0118] Furthermore, the agents can also contain at least one cationic surfactant. Cationic surfactants are surfactants, i.e. surface-active compounds, each with one or more positive charges. Cationic surfactants contain exclusively positive charges. These surfactants are usually composed of a hydrophobic part and a hydrophilic head group, with the hydrophobic part usually consisting of a hydrocarbon backbone (e.g., consisting of one or two linear or branched alkyl chains), and the positive charge(s) are located in the hydrophilic head group. Examples of cationic surfactants are quaternary ammonium compounds which may carry one or two alkyl chains with a chain length of 8 to 28 C atoms as hydrophobic residues, quaternary phosphonium salts substituted with one or more alkyl chains with a chain length of 8 to 28 C atoms or tertiary sulfonium salts.

[0119] Furthermore, the cationic charge can also be part of a heterocyclic ring (e.g., an imidazolium ring or a pyridinium ring) in the form of an onium structure. In addition to the functional unit carrying the cationic charge, the cationic surfactant can also contain other uncharged functional groups, as is the case with esterquats, for example. The cationic surfactants are used in a total amount of 0.1 to 45 wt.%, preferably 1 to 30 wt.%, and most preferably 1 to 15 wt.%, based on the total weight of the respective agent.

[0120] Furthermore, the agents according to the invention can also contain at least one anionic surfactant. Anionic surfactants are surface-active agents with exclusively anionic charges (neutralized by a corresponding countercation). Examples of anionic surfactants are fatty acids, alkyl sulfates, alkyl ether sulfates, and ether carboxylic acids with 12 to 20 carbon atoms in the alkyl group and up to 16 glycol ether groups in the molecule.

[0121] The anionic surfactants are used in a total amount of 0.1 to 45 wt.%, preferably 1 to 30 wt.% and most preferably 1 to 15 wt.% - based on the total weight of the respective agent.

[0122] The agents may also contain other active ingredients, auxiliaries and additives, such as solvents, fatty components such as C 8 -C 30 fatty alcohols, C 8 -C 30 fatty acid triglycerides, C 8 -C 30 fatty acid monoglycerides, C 8 -C 30 fatty acid diglycerides and / or hydrocarbons; structuring agents such as glucose, maleic acid and lactic acid, hair conditioning compounds such as phospholipids, for example lecithin and cephalins; perfume oils, dimethyl isosorbide and cyclodextrins; fiber structure improving agents, in particular mono-, di- and oligosaccharides such as glucose, galactose, fructose, fructose and lactose; dyes for coloring the agent; anti-dandruff agents such as piroctone olamine, zinc omadine and climbazole; amino acids and oligopeptides;Protein hydrolysates of animal and / or plant origin, as well as in the form of their fatty acid condensation products or, where appropriate, anionically or cationically modified derivatives; vegetable oils; sunscreens and UV blockers; active ingredients such as panthenol, pantothenic acid, pantolactone, allantoin, pyrrolidinonecarboxylic acids and their salts, and bisabolol; polyphenols, in particular hydroxycinnamic acids, 6,7-dihydroxycoumarins, hydroxybenzoic acids, catechins, tannins, leucoanthocyanidins, anthocyanidins, flavanones, flavones, and flavonols; ceramides or pseudoceramides; vitamins, provitamins, and vitamin precursors; plant extracts; fats and waxes such as fatty alcohols, beeswax, montan wax, and paraffins; Swelling and penetrating agents such as glycerin, propylene glycol monoethyl ether, carbonates, bicarbonates, guanidines, ureas, and primary, secondary, and tertiary phosphates; opacifiers such as latex, styrene / PVP, and styrene / acrylamide copolymers;Pearlescent agents such as ethylene glycol mono- and distearate and PEG-3 distearate; as well as propellants such as propane-butane mixtures, N 2 O, dimethyl ether, CO 2 and air.

[0123] The expert will select these additional substances based on the desired properties of the agent. Regarding further optional components and the amounts of these components used, reference is expressly made to the relevant manuals known to the expert. The additional active ingredients and excipients are preferably used in the preparations according to the invention in amounts of 0.0001 to 25 wt.%, in particular 0.0005 to 15 wt.%, based on the total weight of the respective agent. Process for coloring keratin materials

[0124] The agents described above - both the ready-to-use agent of the first subject matter of the invention and the agents of the multi-component packaging unit according to the invention of the second subject matter of the invention - are used in processes for dyeing keratinic materials, in particular for dyeing human hair.

[0125] A third object of the present invention is a process for dyeing keratinic material, in particular human hair, comprising the following steps in the order given: (1) Application of a pretreatment agent (V) to the keratinic material, wherein the pretreatment agent (V) contains in a water-containing cosmetic carrier at least one organic silicon compound (a) of the formula (I), as already disclosed in detail in the description of the first subject matter of the invention, (2) Application of a colorant (F) to the keratinic material, wherein the colorant contains at least one color-imparting compound from the group of pigments (b) and at least one film-forming, hydrophilic polymer (c) selected from the group of polyvinylpyrrolidone (PVP) and the copolymers of polyvinylpyrrolidone, as already disclosed in detail in the description of the first subject matter of the invention.

[0126] In the process according to the invention, the keratin materials, in particular human hair, are first treated with a pretreatment agent (V). Subsequently, the actual colorant (F)—which contains the film-forming hydrophilic polymer and the color-imparting compound(s)—is applied to the keratin materials.

[0127] The pretreatment agent (V) itself preferably contains no dyes or color-providing compounds. A characteristic of the pretreatment agent (V) is its content of at least one reactive organic silicon compound (a) of formula (I). The reactive organic silicon compound(s) (a) functionalize the hair surface as soon as they come into contact with it. In this way, a first, still uncolored film is formed. In the second step of the process, a colorant (F) is applied to the hair. During the application of the colorant (F) to the keratin materials, a film also forms on the - now already functionalized - hair surface, with the colorant compounds being embedded in the film and thus deposited on the hair.The film produced in this way "in situ", in which the color-providing compound is embedded, is characterized by outstanding washfastness and a homogeneous color result.

[0128] The pretreatment agent (V) represents the ready-to-use pretreatment agent (V). Most preferably, the pretreatment agent (V) is a mixture of agents (I) and (II) of the multicomponent packaging unit according to the invention. The pretreatment agent (V) thus contains at least one organic silicon compound (a) of the formula (I) described above, where the radicals represent the already mentioned, the preferred, and the particularly preferred substitutes.

[0129] Furthermore, the pretreatment agent (V) contains water, wherein the water originates from the agent (II) of the kit-of-parts according to the invention.

[0131] It is preferred if the pretreatment agent (V) - based on the total weight of the pretreatment agent (V) - has a water content of 15 to 95 wt.%, preferably of 20 to 95 wt.%, more preferably of 25 to 95 wt.%, even more preferably of 30 to 95 wt.% and most preferably of 45 to 95 wt.%.

[0132] In a further very particularly preferred embodiment, a process according to the invention is characterized in that the pretreatment agent (V) - based on the total weight of the pretreatment agent - has a water content of 15 to 95 wt.%, preferably of 20 to 95 wt.%, more preferably of 25 to 95 wt.%, even more preferably of 30 to 95 wt.% and very particularly preferably of 45 to 95 wt.%.

[0133] Particularly resistant dyeings were obtained using an alkaline pretreatment agent (V). The pretreatment agent (V) preferably has a pH of 7.0 to 11.5, preferably 7.5 to 11.0, and particularly preferably 8.0 to 10.5.

[0134] In a further very particularly preferred embodiment, a process according to the invention is characterized in that the pretreatment agent (V) has a pH of 7.0 to 11.5, preferably of 7.5 to 11.0 and particularly preferably of 8.0 to 10.5.

[0135] To establish this alkaline pH, the pretreatment agent (V) preferably contains at least one alkalizing agent, which is added in an amount that ensures the establishment of the optimal pH for the respective hair treatment. The pH values ​​within the meaning of the present invention are pH values ​​measured at a temperature of 22°C.

[0136] Depending on the choice of the desired pH value and depending on the presence of other components in the agent according to the invention, such as acidic or basic salts or buffer components, the amount of alkalizing agent added can vary; usually amounts of 0.01 to 15 wt.% are necessary for this.

[0137] As alkalizing agents, the pretreatment agent (V) may contain, for example, ammonia, alkanolamines and / or basic amino acids.

[0138] The alkanolamines usable in the agent according to the invention are preferably selected from primary amines having a C 2 -C 6 alkyl parent structure carrying at least one hydroxyl group.

[0142] Basic α-aminocarboxylic acids contain at least one asymmetric carbon atom. Within the scope of the present invention, both possible enantiomers can be used equally as specific compounds or as mixtures thereof, particularly as racemates. However, it is particularly advantageous to use the naturally occurring isomer form, usually in the L-configuration.
