Description

Title of the invention: A hair coloring process comprising the application of a composition A comprising two alkoxysilanes, and the application of a composition B comprising a film-forming polymer Technical field of the invention

[0001] The present invention relates to a method for coloring keratin fibers such as hair, comprising applying to the keratin fibers at least one composition A comprising at least one alkoxysilane selected from compounds of formula (I) or formula (1') and at least one alkoxysilane of formula (II), and applying to the keratin fibers at least one composition B comprising at least one film-forming polymer. Said composition A and / or composition B comprise at least one coloring agent selected from pigments, direct dyes, and mixtures thereof. Said composition A and / or composition B comprise at least one compound selected from an amino acid, a polymer derived from an amino acid, and mixtures thereof. Context of the invention

[0002] In the field of staining keratin fibers, particularly human fibers, it is already known to stain keratin fibers by different techniques from direct dyes or pigments for non-permanent staining or from dye precursors for permanent staining.

[0003] There are essentially three types of hair coloring processes:

[0004] a) so-called permanent coloring which has the function of bringing about a significant change in the natural color and which uses oxidation dyes which penetrate the hair fiber and form the dye by a process of oxidative condensation;

[0005] b) non-permanent, semi-permanent or direct coloring, which does not implement the oxidative condensation process and resists 4 or 5 shampoos; consists of dyeing the keratin fibers with dyeing compositions containing direct dyes.

[0006] c) Temporary hair coloring that results in a change to the natural hair color that lasts from one shampoo to the next and serves to enhance or correct a previously achieved shade. It can also be considered a "makeup" process.

[0007] For this latter type of coloring, it is known to use pigments. Indeed, the use of pigment on the surface of keratin fibers generally makes it possible to obtain visible coloring on dark hair since the pigment on the surface masks the natural color of the fiber.

[0008] However, the colors obtained by this coloring method have the disadvantage of having low resistance to shampoos as well as to external agents such as sebum, perspiration, brushing and / or friction.

[0009] There therefore remains a need for a process of coloring keratin fibers, in particular hair, which has the advantage of obtaining a homogeneous and smooth colored coating on the hair, while forming a coating that is resistant to shampoos and to the various aggressions that hair can undergo, such as brushing and / or rubbing, without damaging the hair.

[0010] The applicant has surprisingly discovered that all of these objectives can be achieved by the process according to the present invention. Summary of the invention

[0011] The present invention relates to a method for coloring keratin fibers such as hair, comprising the following steps: a) the application to keratin fibers of at least one composition A comprising: - at least one alkoxysilane selected from the compounds of formula (I) or formula (!') as described below, their oligomers and / or mixtures thereof, and - at least one alkoxysilane of formula (II) as described below, its oligomers and / or mixtures thereof, and b) the application to keratin fibers of at least one composition B comprising: - at least one film-forming polymer, composition A and / or composition B comprising at least one coloring agent selected from pigments, direct colorants, and mixtures thereof, and composition A and / or composition B comprising at least one compound selected from an amino acid, a polymer derived from an amino acid and mixtures thereof.

[0012] The present invention also relates to a device for coloring keratin fibers such as hair, comprising several compartments containing: - in a first compartment, a composition A comprising: - at least one alkoxysilane selected from the compounds of formula (I) or formula (I') as described below, their oligomers and / or mixtures thereof, and - at least one alkoxysilane of formula (II) as described below, its oligomers and / or mixtures thereof, - in a second compartment, a composition B according to the invention comprising: - at least one film-forming polymer, composition A and / or composition B comprising at least one coloring agent chosen from pigments, direct dyes, and their mixtures, and composition A and / or composition B comprising at least one compound chosen from an amino acid, a polymer derived from an amino acid and their mixtures.

[0013] By using this process, colored coatings are applied to the hair, resulting in visible color that remains vibrant through shampooing on all hair types while preserving the physical qualities of the keratin fibers. Such a coating can be resistant to external aggressors such as blow-drying and perspiration.

[0014] For the purposes of the present invention, "residual color after shampooing" means that the color obtained persists after at least one shampoo.

[0098] The pigments that can be used are chosen in particular from among the organic and / or mineral pigments known in the art, in particular those described in Kirk-Othmer's Encyclopedia of Chemical Technology and in Ullmann's Encyclopedia of Industrial Chemistry.

[0099] They may be natural, of natural origin, or not.

[0100] These pigments may be in the form of a powder or pigment paste. They may be coated or uncoated.

[0101] Pigments can, for example, be chosen from mineral pigments, organic pigments, lacquers, special effect pigments such as mother-of-pearl or glitter, and mixtures thereof.

[0102] The pigment may be a mineral pigment. By mineral pigment, we mean any pigment that meets the definition in the Ullmann Encyclopedia in the chapter on inorganic pigments. Examples of mineral pigments useful in the present invention include iron or chromium oxides, manganese violet, ultramarine blue, chromium hydrate, ferric blue, and titanium dioxide.

[0103] The pigment may be an organic pigment. By "organic pigment" is meant any pigment that meets the definition in the Ullmann encyclopedia in the chapter on organic pigment.

[0107] The pigments according to the invention can also be in the form of composite pigments as described in patent EP 1 184 426. These composite pigments can be composed in particular of particles comprising an inorganic core, at least one binder ensuring the fixation of organic pigments on the core, and at least one organic pigment covering at least partially the core.

[0108] The organic pigment can also be a lake. By lake, we mean colorants adsorbed onto insoluble particles, the whole thus obtained remaining insoluble during use.

[0109] The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminium borosilicate, and aluminium.

[0110] Among the colorants, we can mention carminic acid. We can also mention the colorants known under the following names: D & C Red 21 (CI 45 380), D & C Orange 5 (CI 45 370), D & C Red 27 (CI 45 410), D & C Orange 10 (CI 45 425), D & C Red 3 (CI 45 430), D & C Red 4 (CI 15 510), D & C Red 33 (CI 17 200), D & C Yellow 5 (CI 19 140), D & C Yellow 6 (CI 15 985), D & C Green (CI 61 570), D & C Yellow 1 O (CI 77 002), D & C Green 3 (CI 42 053), D & C Blue 1 (CI 42 090).

[0111] As examples of lacquers, we can cite the product known under the following name: D & C Red 7 (CI 15 850 :1).

[0112] The pigment can also be a special effects pigment. Special effects pigments are defined as pigments that generally create a non-uniform and changing colored appearance (characterized by a certain shade, vibrancy, and clarity) depending on the viewing conditions (light, temperature, viewing angles, etc.). They are thus distinct from colored pigments that provide a uniform opaque, semi-transparent, or conventionally transparent tint.

[0113] There are several types of special effect pigments, those with a low refractive index such as fluorescent or photochromic pigments, and those with a higher refractive index such as mother-of-pearl, interference pigments or glitter.

[0114] Examples of special effect pigments include pearlescent pigments such as titanium-coated mica or bismuth oxychloride, colored pearlescent pigments such as titanium-coated mica with iron oxides, iron oxide-coated mica, titanium-coated mica, particularly with ferric blue or chromium oxide, titanium-coated mica with an organic pigment as defined above, and bismuth oxychloride-based pearlescent pigments. Examples of pearlescent pigments include Cellini pearlescent pigments marketed by BASF (Mica-TiO2-lacquer), Prestige pearlescent pigments marketed by Eckart (Mica-TiO2), and Prestige Bronze. marketed by Eckart (Mica-Fe2O3) Colorona marketed by Merck (Mica-TiO2-Fe2O3).

[0115] We can also mention gold-colored mother-of-pearl, notably marketed by BASF under the names Brilliant Gold 212G (Timica), Gold 222C (Cloisonne), Sparkle Gold (Timica), Gold 4504 (Chromalite) and Monarch Gold 233X (Cloisonne); bronze mother-of-pearl, notably marketed by MERCK under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona) and by BASF under the name Super Bronze (Cloisonne); orange mother-of-pearl, notably marketed by BASF under the names Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by MERCK under the names Passion Orange (Colorona) and Matte Orange (17449) (Microna); brown-tinted mother-of-pearl, notably marketed by BASF under the names Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); copper-tinted mother-of-pearl, notably marketed by BASF under the name Copper 340A (Timica);red-tinted mother-of-pearl, notably marketed by MERCK under the name Sienna fine (17386) (Colorona); yellow-tinted mother-of-pearl, notably marketed by BASF under the name Yellow (4502) (Chromalite); red-tinted mother-of-pearl with a gold sheen, notably marketed by BASF under the name Sunstone G012 (Gemtone); pink mother-of-pearl, notably marketed by BASF under the name Tan opale G005 (Gemtone);black mother-of-pearl with a gold sheen, notably marketed by BASF under the name Nu antique bronze 240 AB (Timica); blue mother-of-pearl, notably marketed by MERCK under the name Matte blue (17433) (Microna); white mother-of-pearl with a silver sheen, notably marketed by MERCK under the name Xirona Silver; and orange-pink-green-gold mother-of-pearl, notably marketed by MERCK under the name Indian summer (Xirona), and their mixtures.

[0116] As further examples of nacres, we can also mention particles comprising a borosilicate substrate coated with titanium oxide.

[0117] Particles with a glass substrate coated with titanium oxide are notably sold under the name METASHINE MC1080RY by the company TOYAL.

[0118] Finally, examples of mother-of-pearl include polyethylene terephthalate flakes, particularly those marketed by Meadowbrook Inventions under the name Silver IP 0.004X0.004 (silver flakes). Multilayer pigments based on synthetic substrates such as alumina, silica, calcium sodium borosilicate or calcium aluminum borosilicate, and aluminum can also be considered.

[0119] Special effect pigments can also be selected from the particles Reflecting particles, that is to say, particles whose size, structure (particularly the thickness of the layer(s) that constitute them), their physical and chemical nature, and surface condition allow them to reflect incident light. This reflection can, where applicable, be intense enough to create visible highlights on the surface of the composition or mixture when applied to the makeup base; these are brighter spots that contrast with their surroundings, appearing to shine.

[0120] The reflective particles can be selected so as not to significantly alter the coloring effect generated by the coloring agents associated with them, and more particularly so as to optimize this effect in terms of color rendering. They may, in particular, have a yellow, pink, red, bronze, orange, brown, gold, and / or copper color or reflection.

[0121] These particles can have various shapes, including being platelet-shaped or globular, particularly spherical.

[0122] Reflective particles, whatever their shape, may or may not have a multilayer structure and, in the case of a multilayer structure, for example at least one layer of uniform thickness, in particular of a reflective material.

[0123] When the reflective particles do not have a multilayer structure, they can be composed, for example, of metal oxides, in particular titanium or iron oxides obtained by synthesis.

[0124] When reflective particles have a multilayer structure, they may, for example, comprise a natural or synthetic substrate, in particular a synthetic substrate at least partially coated by at least one layer of a reflective material, in particular at least one metal or metallic material. The substrate may be monomaterial, multimaterial, organic and / or inorganic.

[0125] More particularly, it may be selected from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, synthetic mica and their mixtures, this list not being exhaustive.

[0126] The reflective material may include a layer of metal or a metallic material.

[0127] Reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0128] As further examples of reflective particles comprising a mineral substrate coated with a layer of metal, one can also mention particles comprising a borosilicate substrate coated with silver.

[0129] Silver-coated glass substrate particles in the form of platelets are sold under the name MICROGLASS METASHINE REFSX 2025 PS by the TOYAL company. Particles with a glass substrate coated with nickel / chromium / molybdenum alloy are sold under the name CRYSTAL STAR GF 550, GF 2525 by this same company.

[0130] Particles comprising a metallic substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze, titanium may also be used, said substrate being coated with at least one layer of at least one metallic oxide such as titanium oxide, aluminum oxide, iron oxide, cerium oxide, chromium oxide, silicon oxides and mixtures thereof.

[0131] An example can be cited as aluminium, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.

[0132] Other examples include non-substrate interference pigments such as liquid crystals (Wacker's Helicones HC) and interference holographic glitter (Spectratek's Geometry Pigments or Spectra f / x). Special effect pigments also include fluorescent pigments, whether daylight fluorescent or ultraviolet fluorescent, phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots, marketed, for example, by Quantum Dots Corporation.

[0133] The variety of pigments that can be used in the present invention makes it possible to obtain a rich palette of colors, as well as particular optical effects such as metallic, interference effects.

[0134] The size of the pigment used in the composition according to the present invention is generally between 5 nm and 200 µm, preferably between 7 nm and 80 µm, and more preferably between 10 nm and 50 µm.

[0135] The pigments can be dispersed within the composition by means of a dispersing agent.

[0136] The dispersing agent serves to protect the dispersed particles from agglomeration or flocculation. This dispersing agent may be a surfactant, an oligomer, a polymer, or a mixture of several of these, possessing one or more functionalities with a strong affinity for the surface of the particles to be dispersed. In particular, they may adhere physically or chemically to the surface of the pigments. These dispersants also have at least one functional group that is compatible with or soluble in the continuous medium.In particular, esters of 12-hydroxystearic acid are used, especially C8 to C20 fatty acids and polyols such as glycerol, diglycerin, such as poly(12-hydroxystearic acid) stearate with a molecular weight of about 750g / mol such as that sold under the name Solsperse 21 000 by the company Avecia, polygyceryl-2 dipolyhydroxystearate (name CTFA) sold under the reference. Dehymyls PGPH by the company Henkel or polyhydroxy stearic acid such as that sold under the reference Arlacel P100 by the company Uniqema and their mixtures.

[0137] As another dispersant that can be used in the compositions of the invention, we can mention quaternary ammonium derivatives of polycondensed fatty acids such as Solsperse 17 000 sold by Avecia, poly dimethylsiloxane / oxypropylene mixtures such as those sold by Dow Corning under the references DC2-5185, DC2-5225 C.

[0138] The pigments used in the composition can be surface treated with an organic agent.

[0139] Thus the pigments previously surface treated useful in the context of the invention are pigments which have undergone totally or partially a surface treatment of a chemical, electronic, electro-chemical, mechano-chemical or mechanical nature, with an organic agent such as those described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, p. 53-64 before being dispersed in the composition according to the invention.These organic agents can be chosen, for example, from waxes, such as carnauba wax and beeswax; fatty acids, fatty alcohols and their derivatives, such as stearic acid, hydroxystearic acid, stearyl alcohol, hydroxystearyl alcohol, lauric acid and their derivatives; anionic surfactants; lecithins; sodium, potassium, magnesium, iron, titanium, zinc or aluminum salts of fatty acids, for example aluminum stearate or laurate; polyethylene; (meth)acrylic polymers, for example polymethylmethacrylates; polymers and copolymers containing acrylate motifs; alkanoamines; fluorinated organic compounds, for example perfluoroalkyl ethers; fluorosilicone compounds.

[0140] The surface-treated pigments useful in the composition may also have been treated by a mixture of these compounds and / or have undergone several surface treatments.

[0141] The surface-treated pigments useful in the context of the present invention can be prepared using surface treatment techniques well known to those skilled in the art or found as such in the commercial market.

[0142] Preferably, the surface-treated pigments are covered by an organic layer.

[0143] The organic agent with which the pigments are treated can be deposited on the pigments by solvent evaporation, chemical reaction between the molecules of the surfactant or creation of a covalent bond between the surfactant and the pigments.

[0144] Surface treatment can thus be carried out, for example, by a chemical reaction of a surfactant with the surface of the pigments and the creation of a covalent bond between the surfactant and the pigments or fillers. This method is notably described in US patent 4,578,266.

[0145] Preferably, an organic agent covalently linked to the pigments will be used.

[0146] The surface treatment agent can represent from 0.1 to 50% by weight of the total weight of the pigment treated on the surface, preferably from 0.5 to 30% by weight, and even more preferably from 1 to 20% by weight of the total weight of the pigment treated on the surface.

[0147] Preferably, the surface treatments of the pigments are chosen from the following treatments: - a PEG-Silicone treatment such as the AQ surface treatment marketed by LCW; - a Methicone treatment such as the SI surface treatment marketed by LCW; - a Dimethicone treatment such as the Covasil 3.05 surface treatment marketed by LCW; - a Dimethicone / Trimethylsiloxysilicate treatment such as the Covasil 4.05 surface treatment marketed by LCW; - a Magnesium Myristate treatment such as the MM surface treatment marketed by LCW; - a Dimyristate Aluminium treatment such as the MI surface treatment marketed by Miyoshi; - a Perfluoropolymethylisopropyl ether treatment such as the FHC surface treatment marketed by LCW; - an Isostearyl Sebacate treatment such as the HS surface treatment marketed by Miyoshi; - a Perfluoroalkyl Phosphate treatment such as the PF surface treatment marketed by Daito; - an acrylate / dimethicone copolymer and perfluoalkyl phosphate treatment such as the FSA surface treatment marketed by Daito; - a Polymethylhydrogen siloxane / Perfluoroalkyl Phosphate treatment such as the FS01 surface treatment marketed by Daito; - an Acrylate / Dimethicone Copolymer treatment such as the ASC surface treatment marketed by Daito; - an Isopropyl Titanium Triisostearate treatment such as the ITT surface treatment marketed by Daito; - an Acrylate copolymer treatment such as the APD surface treatment marketed by Daito; - a Perfluoroalkyl Phosphate / Isopropyl Titanium Triisostearate treatment such as the PF + ITT surface treatment marketed by Daito.

[0148] According to a particular embodiment of the invention, the dispersing agent is present with organic or inorganic pigments in submicron-sized particulate form in the coloring composition.

[0149] By "sub-micronic" or in English "sub-micronic" is meant pigments whose particle size has been micronized by micronization method and whose average particle size is less than one micrometer (pm), in particular between 0.1 and 0.9 pm, and preferably between 0.2 and 0.6 pm.

[0150] According to one embodiment, the dispersing agent and the pigment(s) are present in an amount (dispersant: pigment) between 1:4 and 4:1, particularly between 1.5:3.5 and 3.5:1 or better between 1.75:3 and 3:1.

[0151] The dispersing agent(s) may therefore have a silicone backbone, such as silicone polyether and amino-silicone dispersants, other than the amino silicones or alkoxysilanes of formula (I) or formula (T) previously described in the application. Suitable dispersing agents include: - amino-silicones, i.e. silicones comprising one or more amino groups, such as those marketed under the names and references: BYK LPX 21879, by BYK, GP-4, GP-6, GP-344, GP-851, GP-965, GP-967 and GP-988-1, marketed by Genesee les polymers, - silicone acrylates such as Tego ® RC 902, Tego ® RC 922, Tego ® RC 1041, and Tego ® RC 1043, marketed by Evonik, - polydimethylsiloxane (PDMS) silicones with carboxylic groups such as X-22162 and X-22370 by Shin-Etsu, silicone epoxy such as GP-29, GP-32, GP-502, GP-504, GP-514, GP-607, GP-682, and GP-695, by Genesee Polymers, or Tego ® RC 1401, Tego ® RC 1403, Tego ® RC 1412, by Evonik.

[0152] According to a particular embodiment, the dispersing agent(s) are of the amino-silicone type, different from the amino silicones or alkoxysilanes of formula (I) or formula (T) previously described in the application and are cationic.

[0153] Preferably, the pigment(s) is / are chosen from mineral, mixed mineral-organic or organic pigments.

[0154] In one embodiment of the invention, the pigment(s) according to the invention are organic pigments. In another embodiment of the invention, the pigment(s) according to the invention are mineral pigments.

[0155] Composition A and / or composition B according to the invention may (can) comprise one or more direct dye(s).

[0156] By "direct dye," we mean natural and / or synthetic dyes, different from oxidation dyes. These are dyes that will diffuse superficially onto the fiber.

[0157] They can be ionic or non-ionic, preferably anionic, cationic or non-ionic.

[0158] Examples of suitable direct dyes that may be mentioned include azo direct dyes; (poly)methine dyes such as cyanines, hemicyanines and styryls; carbonyl dyes; azine dyes; nitro(hetero)aryl dyes; tri(hetero)arylmethane dyes; porphyrin dyes; phthalocyanine dyes and natural direct dyes, alone or in mixtures.

[0159] Direct dyes are preferably cationic direct dyes. Examples include the hydrazono cationic dyes of formulas (III) and (IV), and the azo cationic dyes (V) and (VI) shown below: (III) Her-C(Ra)=NN <Rb)-Ar, Q Het <N0U)-N=C(Rb)-Ar, Q- HeF-N=N-Ar Q- Ar <N=N-Ar’\ Q- formulas (III) to (VI) in which: - Het+ represents a cationic heteroaryl radical, preferably with endocyclic cationic charge such as imidazolium, indolium, or pyridinium, possibly preferentially substituted by at least one (Ci-C8)alkyl group such as methyl; - Ar+ represents an aryl radical, such as phenyl or naphthyl, with an exocyclic cationic charge, preferably ammonium, particularly tri(Ci-C8)alkyl-ammonium such as trimethylammonium; - Ar represents an aryl group, in particular phenyl, possibly substituted, preferably by one or more electron-donating groups such as i) (Ci-C8)alkyl possibly substituted, ii) (Ci-C8)alkoxy possibly substituted, iii) (di)(Ci-C8)(alkyl)amino possibly substituted on the alkyl group(s) by a hydroxyl group, iv) aryl(Ci-C8)alkylamino, v) N-(Ci-C8)alkyl-N-aryl(Ci-C8)alkylamino possibly substituted or else Ar represents a julolidine group; - Ar” represents a (hetero)aryl group possibly substituted such as phenyl or pyrazolyl possibly substituted, preferably by one or more (CrC8)alkyl, hydroxyl, (di)(Ci-C8)(alkyl)amino, (CrC8)alkoxy or phenyl groups; - Ra and Rb, identical or different, representing a hydrogen atom or a (CrC8)alkyl group, possibly substituted, preferably by a
