Description

Title of the invention: Process for coloring hair comprising the application of a composition C comprising a metallic compound Technical field of the invention

[0001] The present invention relates to a process for coloring keratin fibers such as hair, comprising a step of applying to the keratin fibers at least one composition C comprising at least one metallic compound, a step of applying to the keratin fibers at least one composition A comprising at least one alkoxysilane chosen from the compounds of formula (I) or of formula (I'), and at least one alkoxysilane of formula (II), and a step of 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 chosen from pigments, direct dyes, and mixtures thereof. Steps i), ii) and iii) are carried out successively i), then ii), then iii) or then ii), then i), then iii) or then ii), then iii) then i). Background to the invention

[0002] In the field of coloring keratin fibers, in particular human fibers, it is already known to color keratin fibers by different techniques using direct dyes or pigments for non-permanent colorings or dye precursors for permanent colorings.

[0003] There are basically three types of hair coloring process:

[0004] a) so-called permanent coloring which has the function of bringing about a significant modification of the natural color and which uses oxidation dyes which penetrate into 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 involve the oxidative condensation process and is resistant to 4 or 5 shampoos; consists of dyeing keratin fibers with dyeing compositions containing direct dyes.

[0006] c) temporary coloring which results in a change in the natural color of the hair which lasts from one shampoo to the next and which serves to enhance or correct a shade already obtained. It can also be likened to a “make-up” process.

[0007] For this last 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 colorations on dark hair since the surface pigment masks the natural color of the fiber.

[0008] However, the colorations 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 rubbing.

[0009] There therefore remains a need to have a process for 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 various attacks that the hair may be subjected to, 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 method according to the present invention. Summary of the invention

[0011] The subject of the present invention is a process for coloring keratin fibers such as hair, comprising: i) a step of applying to the keratin fibers at least one composition C comprising at least one metallic compound, ii) a step of applying to the keratin fibers at least one composition A comprising: - at least one alkoxysilane chosen from the compounds of formula (I) or of formula (!) as described below, their oligomers and / or their mixtures, and - at least one alkoxysilane of formula (II) as described below, its oligomers and / or their mixtures, and iii) a step of applying to the keratin fibers at least one composition B 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; it being understood that steps i), ii) and iii) are carried out successively i), then ii), then iii) or then ii), then i), then iii) or then ii), then iii) then i).

[0013] -in a third compartment, a composition C comprising at least one metallic compound, composition A and / or composition B comprising at least one coloring agent chosen from pigments, direct dyes, and their mixtures.

[0014] By using this process, colored coatings are obtained on the hair, making it possible to obtain a visible coloring on all types of hair in a way that remains after shampooing while preserving the physical qualities of the keratin fibers.

Also included are dyes 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).

[0187] As examples of lacquers, we can cite the product known under the following name: D & C Red 7 (CI 15 850:1).

[0188] The pigment may also be a special effect pigment. Special effect pigments are understood to mean pigments that generally create a colored appearance (characterized by a certain shade, a certain vividness and a certain clarity) that is non-uniform and changes depending on the viewing conditions (light, temperature, viewing angles, etc.). They are thus opposed to colored pigments that provide a conventional uniform opaque, semi-transparent or transparent shade.

[0189] 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 nacres, interference pigments or glitter.

[0190] Examples of special effect pigments that may be mentioned are pearlescent pigments such as mica coated with titanium or bismuth oxychloride, colored pearlescent pigments such as mica coated with titanium and iron oxides, mica coated with iron oxide, mica coated with titanium and in particular ferric blue or chromium oxide, mica coated with titanium and an organic pigment as defined above, as well as pearlescent pigments based on bismuth oxychloride. As pearlescent pigments, we can cite Cellini pearlescents marketed by BASF (Mica-TiO2-lacquer), Prestige marketed by Eckart (Mica-TiO2), Prestige Bronze marketed by Eckart (Mica-Fe2O3) and Colorona marketed by Merck (Mica-TiO2-Fe2O3).

[0191] Mention may also be made of gold-colored mother-of-pearls marketed in particular by BASF under the name Brillant gold 212G (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne); bronze mother-of-pearls marketed in particular by MERCK under the name Bronze fine (17384) (Colorona) and Bronze (17353) (Colorona) and by BASF under the name Super bronze (Cloisonne); orange mother-of-pearls marketed in particular by BASF under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by MERCK under the name Passion orange (Colorona) and Matte orange (17449) (Microna); brown-tinted mother-of-pearl, notably marketed by BASF under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); copper-reflecting 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 tint, 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 pinkish-orange, golden-green mother-of-pearl notably marketed by MERCK under the name Indian summer (Xirona) and their mixtures.;

[0192] Still as an example of nacres, we can also cite particles comprising a borosilicate substrate coated with titanium oxide.

[0193] Particles with a glass substrate coated with titanium oxide are notably sold under the name METASHINE MC1080RY by the company TOYAL.

[0194] Finally, as examples of nacres, we can also cite polyethylene terephthalate flakes, in particular those marketed by the company Meadowbrook Inventions under the name Silver IP 0.004X0.004 (silver flakes). We can also consider multilayer pigments based on synthetic substrates such as alumina, silica, calcium sodium borosilicate or calcium aluminum borosilicate, and aluminum.

[0195] The special effect pigments may also be chosen from reflective particles, that is to say in particular particles whose size, structure, in particular the thickness of the layer(s) which constitute it and their physical and chemical nature, and surface condition, enable them to reflect incident light. This reflection may, where appropriate, have sufficient intensity to create on the surface of the composition or mixture, when the latter is applied to the support to be made up, highlights visible to the naked eye, that is to say brighter points which contrast with their environment by appearing to shine.

[0196] The reflective particles may 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 more particularly have a yellow, pink, red, bronze, orange, brown, gold and / or copper color or reflection.

[0197] These particles can have various shapes, in particular being platelet-shaped or globular, in particular spherical.

[0198] The reflective particles, whatever their shape, may have a multi-layer structure or not and, in the case of a multi-layer structure, for example at least one layer of uniform thickness, in particular of a reflective material.

[0199] When the reflective particles do not have a multilayer structure, they may be composed, for example, of metal oxides, in particular titanium or iron oxides obtained by synthesis.

[0200] When the reflective particles have a multi-layer structure, they may for example comprise a natural or synthetic substrate, in particular a synthetic substrate at least partially coated with at least one layer of a reflective material, in particular at least one metal or metallic material. The substrate may be single-material, multi-material, organic and / or inorganic.

[0201] More particularly, it can be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, synthetic mica and their mixtures, this list not being limiting.

[0202] The reflective material may comprise a layer of metal or a metallic material.

[0203] Reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0204] Still as an example of reflective particles comprising a mineral substrate coated with a layer of metal, mention may also be made of particles comprising a borosilicate substrate coated with silver.

[0205] Platelet-shaped particles with a silver-coated glass substrate are sold under the name MICROGLASS METASHINE REFSX 2025 PS by the company TOYAL. Particles with a nickel / chromium / molybdenum alloy-coated glass substrate are sold under the name CRYSTAL STAR GF 550, GF 2525 by the same company.

[0206] It is also possible to use particles comprising a metallic substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, steel, bronze, titanium, 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.

[0207] Examples include aluminum, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.

[0208] Mention may also be made of interference effect pigments not fixed on a substrate such as liquid crystals (Helicones HC from Wacker), interference holographic flakes (Geometry Pigments or Spectra f / x from Spectratek). Special effect pigments also include fluorescent pigments, whether they are substances that fluoresce in daylight or that produce ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments and quantum dots, marketed for example by the company Quantum Dots Corporation.

[0209] 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 and interference effects.

[0210] The size of the pigment used in the composition according to the present invention is generally between 5 nm and 200 qm, preferably between 7 nm and 80 qm, and more preferably between 10 nm and 50 qm.

[0211] The pigments may be dispersed in the composition using a dispersing agent.

[0212] The dispersing agent serves to protect the dispersed particles against agglomeration or flocculation. This dispersing agent may be a surfactant, an oligomer, a polymer or a mixture of several of them, carrying one or more functionalities having a strong affinity for the surface of the particles to be dispersed. In particular, they may attach physically or chemically to the surface of the pigments. These dispersants further have at least one functional group compatible with or soluble in the continuous medium. In particular, esters of 12-hydroxystearic acid, in particular, and of C8 to C20 fatty acids and polyols such as glycerol, diglycerin, such as poly(12-hydroxystearic acid) stearate with a molecular weight of approximately 750g / mol, such as that sold under the name Solsperse 21 000 by the company Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold under the reference Dehymyls PGPH by the company Henkel, or polyhydroxystearic acid such as that sold under the reference Arlacel P100 by the company Uniqema, and mixtures thereof, are used.

[0213] As another dispersant that can be used in the compositions of the invention, mention may be made of quaternary ammonium derivatives of polycondensed fatty acids such as Solsperse 17 000 sold by the company Avecia, poly dimethylsiloxane / oxypropylene mixtures such as those sold by the company Dow Corning under the references DC2-5185, DC2-5225 C.

[0214] The pigments used in the composition may be surface-treated with an organic agent.

[0215] Thus, the previously surface-treated pigments useful in the context of the invention are pigments which have undergone totally or partially a surface treatment of a chemical, electronic, electrochemical, mechanochemical or mechanical nature, with an organic agent such as those which are described in particular in Cosmetics and Toiletries, February 1990, Vol. 105, p. 53-64 before being dispersed in the composition in accordance with the invention.These organic agents may be chosen, for example, from waxes, for example 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 units; alkanoamines; fluorinated organic compounds, for example perfluoroalkyl ethers; fluoro-silicon compounds.

[0216] The surface-treated pigments useful in the composition may also have been treated with a mixture of these compounds and / or have undergone several surface treatments.

[0217] The surface-treated pigments useful in the context of the present invention can be prepared according to surface treatment techniques well known to those skilled in the art or found as such commercially.

[0218] Preferably, the surface-treated pigments are covered by an organic layer.

[0219] 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.

[0220] The surface treatment can thus be carried out for example by chemical reaction of a surfactant with the surface of the pigments and creation of a covalent bond between the surfactant and the pigments or fillers. This method is described in particular in US patent 4,578,266.

[0221] Preferably, an organic agent covalently bound to the pigments will be used.

[0222] The surface treatment agent may represent from 0.1 to 50% by weight of the total weight of the surface-treated pigment, preferably from 0.5 to 30% by weight, and even more preferably from 1 to 20% by weight of the total weight of the surface-treated pigment.

[0223] Preferably, the surface treatments of the pigments are chosen from the following treatments: - a PEG-Silicone treatment like 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; - an Aluminum Dimyristate 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 and Perfluoroalkyl Phosphate Copolymer 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 like 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 like the PF + ITT surface treatment marketed by Daito.

[0224] According to a particular embodiment of the invention, the dispersing agent is present with organic or inorganic pigments in particulate form of sub-micron size in the coloring composition.

[0225] 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.

[0226] According to one embodiment, the dispersing agent and the pigment(s) are present in an amount (dispersant: pigment) of 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.

[0227] The dispersing agent(s) may therefore have a silicone backbone, such as silicone polyether and amino-silicone dispersants, different from the amino silicones or alkoxysilanes of formula (I) or formula (T) previously described in the application. Among the suitable dispersing agents, mention may be made of: - 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 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.

[0228] According to a particular embodiment, the dispersing agent(s) are of amino-silicone type, different from the amino silicones or alkoxysilanes of formula (I) or formula (T) previously described in the application and are cationic.

[0229] Preferably, the pigment(s) is(are) chosen from mineral, mixed mineral-organic or organic pigments.

[0230] In one variant of the invention, the pigment(s) according to the invention are organic pigments. In another variant of the invention, the pigment(s) according to the invention are mineral pigments.

[0231] Composition A and / or composition B according to the invention may comprise one or more direct dye(s).

[0232] By "direct dye" we mean natural and / or synthetic dyes, different from oxidation dyes. These are dyes which will diffuse superficially on the fiber.

[0233] They can be ionic or non-ionic, preferably anionic, cationic or non-ionic.

[0234] 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 as mixtures.

[0239] The direct dyes may be chosen from anionic direct dyes. The anionic direct dyes of the invention are dyes commonly called “acid” direct dyes for their affinity with alkaline substances. By anionic direct dyes is meant any direct dye comprising in its structure at least one CO2R or SO3R substituent with R denoting a hydrogen atom or a cation originating from a metal or an amine, or an ammonium ion.

[0370] Two distinct protocols are applied to the strands of hair: - either composition C is applied to the locks of hair (process according to the invention), - either composition C is not applied to the strands of hair (comparative process).

[0371] * Protocol with compositions Al + B1

[0372] When composition C is applied to strands of hair, composition C is applied with the finger to strands of dry brown hair (HT4), at a rate of 1 g of composition per gram of strand.

[0373] The locks of hair are left for 5 minutes at room temperature.

[0374] The strands of hair are then wrung out between the fingers.

[0375] Compositions Al' and Al” are mixed in a 50 / 50 ratio to obtain composition AL

[0376] Composition Al is applied to the locks of hair treated with composition C and to locks of hair not treated with composition C (locks of dry brown hair (HT4)), at a rate of 1 g of composition per gram of lock.

[0377] The locks of hair are left for 2 minutes at room temperature.

[0378] Composition B1 is then applied to the locks of hair treated with composition Al + C, at a rate of 1 g of composition per gram of lock.

[0379] Composition B1 is also applied to the locks of hair treated only with composition Al, at a rate of 1 g of composition per gram of lock.

[0380] The locks of hair are left for 5 minutes at room temperature.

[0381] The strands of hair are then dried with a hairdryer for 2 minutes.

[0382] The hair strands are left at room temperature for 24 hours.

[0383] *Protocol with compositions A2 + B2

[0384] Composition A2 is applied with the finger to strands of dry brown hair (HT4), at a rate of 1 g of composition per gram of strand.

[0385] The locks of hair are left for 5 minutes at room temperature.

[0386] The locks of hair are then wiped with absorbent paper and not dried.

[0387] Composition C is applied with the finger to certain locks of hair treated with composition A2, at a rate of 1 g of composition per gram of lock.

[0388] The locks of hair are left for 2 minutes at room temperature.

[0389] The strands of hair are then wrung out between the fingers.

[0390] Composition B2 is then applied to the locks of hair treated with compositions A2 + C and to locks of hair treated only with composition A2, at a rate of 1 g of composition per gram of lock.

[0391] The locks of hair are left for 2 minutes at room temperature.

[0392] The strands of hair are then dried with a hairdryer for 2 minutes.

[0393] The hair strands are left at room temperature for 24 hours.

[0394] The locks of hair thus colored are then subjected to shampooing in order to evaluate the tenacity (the persistence) of the coloring obtained by shampooing, according to the shampooing protocol described below. Shampoo protocol:

[0395] The hair strands are washed using a standard shampoo (Garnier Ultra Doux).

[0396] The strands of hair are then rinsed, combed and dried with a hairdryer.

[0397] The following shampoo is carried out on the strands obtained after applying the hair dryer. Results :

[0398] The color persistence of the strands was evaluated in the CIE L*a*b* system, using a Minolta Spectrophotometer CM3600A colorimeter (illuminant D65, angle 10°, specular component included).

[0399] In this L*a*b* system, L* represents the color intensity, a* indicates the green / red color axis and b* the blue / yellow color axis.

[0400] The persistence of the color is evaluated by the color difference AE between the colored strands before shampooing, then after having undergone 1 shampoo according to the protocol described above. The lower the AE value, the more the color persists after shampooing.

[0401] The value of AE is calculated according to the following equation:

[0402] [Math.l] AS - (ïL ■ L 'r -i- ("' ' s, 'A;?;' - te,

[0403] In this equation, L*a*b* represent the values ​​measured after coloring the hair and after shampooing, and L0*a0*b0* represent the values ​​measured after coloring the hair but before shampooing.

[0404] [Tableauxô] Compositions Number of shampoos L* a* b* AE Compositions Al + B1 (comparative) 0 37.0 1.0 -2.0 - 1 30.1 1.9 0.5 7.4 Compositions C+Al + B1 (invention) 0 37.1 0.8 -2.0 - 1 34.4 1.7 -0.3 3.3 Compositions A2 + B2 (comparative) 0 43.9 1.1 -1.8 - 1 25.4 2.3 1.9 18.9 Compositions A2 + C+ B2 (invention) 0 45.9 0.7 -1.9 - 1 31.9 1.1 -1.8 14.0

[0405] The locks of hair colored with the compositions C + Al + B1 according to the invention, and washed with a shampoo, have low AE values ​​compared to the locks of hair colored with the compositions Al + B1 only.

[0406] The locks of hair colored with compositions A2 + C + B2 according to the invention, and washed with a shampoo, have low AE values ​​compared to the locks of hair colored with compositions A2 + B2 only.

[0407] Thus, the colored coating of the keratin fibers obtained with the compositions C + Al + B1 according to the invention or with the compositions A2 + C + B2 according to the invention, has good color retention. Indeed, the locks of hair colored with the compositions C + Al + B1 according to the invention or with the compositions A2 + C + B2 according to the invention and washed with a shampoo have good color retention. < / n=n-ar,>
