Description

Title of the invention: Process for treating keratin fibers comprising the applications of a coloring composition based on a particular polymer then of a composition based on fatty substances and surfactant

[0001] The present invention relates to the field of cosmetic treatment of keratin fibers, preferably hair. It thus aims to propose new treatment methods comprising, firstly, the coloring of said keratin fibers by the application of a coloring composition based on a particular polymer with acetoacetate units, which have excellent technical performances, in particular in terms of the durability of the colors that it makes it possible to obtain, then, secondly, the removal of the coloring of said keratin fibers (or "removal of makeup from the keratin fibers") by the application of a second composition based on a non-silicone fatty substance and a non-ionic surfactant to the colored keratin fibers.

[0002] More specifically, the subject of the present invention is a process for treating keratin fibers such as hair, comprising the application to the keratin fibers of at least one coloring composition B comprising at least one coloring agent and at least one polymer P comprising repeating units derived from at least one monomer of formula (III), then the application to the keratin fibers thus colored of at least one composition D, different from composition B, comprising at least one non-ionic surfactant and at least one non-silicone fatty substance.

[0003] In the field of coloring hair keratin fibers, it is known to color fibers using different techniques using direct dyes or pigments in order to obtain non-permanent colorings or dye precursors in order to obtain permanent colorings.

[0004] There are basically three types of hair coloring process:

[0005] 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;

[0006] 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;

[0007] c) temporary coloring which results in a modification of the natural color hair that lasts from one shampoo to the next and is used to enhance or correct an already achieved shade. It can also be likened to a hair "makeup" process.

[0008] Another coloring method consists of using pigments. Indeed, the use of pigments on the surface of keratin fibers generally makes it possible to obtain visible colorings on dark hair since the pigment on the surface masks the natural color of the fiber. However, the colorings 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] Thus, so-called hair makeup products or "Hair Make-up" have recently been developed, which offer temporary hair coloring that lasts after 1 to 3 shampoos. They constitute an alternative, particularly attractive to consumers, to permanent coloring provided that the color effect maintains good resistance to contact with water and a few shampoos. This requirement can be met in particular through the use of effective film-forming agents.

[0010] Thus, document FR 2 741 530 proposes for this purpose, for the temporary coloring of keratin fibers, the use of a dispersion of film-forming polymer particles comprising at least one acid function and at least one pigment dispersed in the continuous phase of said dispersion. The colors obtained by this coloring method nevertheless have the disadvantage of being removed too quickly when shampooing.

[0011] It is also proposed in document FR 2 907 678 to produce colored coatings of the hair from a composition comprising a poly-siloxane / polyurea block copolymer and a pigment. However, with such a composition, the coatings obtained are not always very homogeneous and the individualization of the hair is not always satisfactory.

[0012] Furthermore, the user of temporary hair colorings wishes at some point to regain their natural color. However, there are no satisfactory compositions for completely removing ("removing makeup") this type of temporary coloring from keratin fibers, when it remains after shampooing.

[0013] There therefore remains a real need to have treatment processes which make it possible to dye keratin fibres, in particular hair, which have the advantage of obtaining a homogeneous dyeing of the fibres, whilst forming a coating which is resistant to shampoos, sebum and various attacks which the hair may be subjected to such as brushing, perspiration and / or friction, but which is easily removed using a specific composition.

[0014] The present invention makes it possible to meet these needs.

[0015] The subject of the present invention is a process, preferably cosmetic, for treating keratin fibers such as hair, comprising at least the following steps: i) a step of applying to the keratin fibres at least one colouring composition B comprising at least one colouring agent and at least one polymer P comprising repeating units derived from at least one monomer of formula (III): in which: - Ra represents a hydrogen atom or a linear or branched (Ci-C4)alkyl group, - Rb and Rc, identical or different, represent a hydrogen atom or a linear or branched (Ci-C4)alkyl group, - Rd represents a linear or branched (CrC4)alkyl group, and - L represents a linear or branched (Ci-C6)alkylene group, or cycloalkylene; then ii) a step of applying to the colored keratin fibers at least one composition D, different from composition B, comprising: - at least one non-ionic surfactant - at least one non-silicone fatty substance.

[0016] According to the invention, step i) of applying the coloring composition B is therefore carried out before step ii) of applying the composition D, which does not exclude one or more intermediate steps between steps i) and ii).

[0017] The application of the coloring composition B according to the invention makes it possible to obtain homogeneous and smooth colored coatings. It provides visible coloring on all types of fibers, resistant to sebum and water, and in particular to shampoos. Such a coating can be resistant to the various external aggressions that keratin fibers can undergo such as, for example, blow-drying, brushing, rubbing and perspiration.

[0018] Furthermore, the temporary coloration of the keratin fibers treated by means of the coloring composition B can easily be removed by means of the composition D, either immediately after the application of the coloring composition B (i.e. from a few minutes to a few hours), or after a certain time (i.e. from a few days to a few weeks), after the application of the coloring composition B. The user then regains the original color of their keratin fibers (i.e. before the implementation of the treatment process according to the invention).

[0019] The present invention also relates to a multi-compartment device comprising a first compartment containing a composition B comprising at least one coloring agent and at least one polymer P as described below, and a second compartment containing a composition D different from composition B, comprising at least one non-ionic surfactant and at least one non-silicone fatty substance as described below.

[0029] The pigments which can be used are in particular chosen from pigments organic and / or mineral materials known to the art, in particular those described in Kirk-Othmer's Encyclopedia of Chemical Technology and in Ullmann's Encyclopedia of Industrial Chemistry.

[0030] They can be natural, of natural origin, or not.

[0031] These pigments can be in the form of powder or pigment paste. They can be coated or uncoated.

[0032] The pigments may for example be chosen from mineral pigments, organic pigments, lakes, special effect pigments such as mother-of-pearl or glitter, and mixtures thereof.

These composite pigments may be composed in particular of particles comprising an inorganic core, at least one binder ensuring the fixing of the organic pigments on the core, and at least one organic pigment at least partially covering the core.

[0039] The organic pigment may also be a lake. By lake is meant dyes adsorbed on insoluble particles, the whole thus obtained remaining insoluble during use.

[0040] The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium and sodium borosilicate or calcium and aluminum borosilicate, and aluminum.

[0041] Among the colorants, we can cite carminic acid. 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).

[0042] As examples of lacquers, we can cite the product known under the following name: D & C Red 7 (CI 15 850:1).

[0043] The pigment may also be a special effect pigment. Special effect pigments are understood to mean pigments which generally create a colored appearance (characterized by a certain shade, a certain liveliness and a certain clarity) which is non-uniform and changes depending on the observation conditions (light, temperature, observation angles, etc.). They are thus opposed to colored pigments which provide a conventional uniform opaque, semi-transparent or transparent shade.

[0044] 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.

[0045] Examples of special effect pigments include 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, mention may be made of Cellini pearlescent pigments marketed by BASF (Mica-TiO 2-lake), Prestige marketed by Eckart (Mica-TiO2), Prestige Bronze marketed by Eckart (Mica-Fe2O3), Syncrystal marketed by Eckart (Mica-TiO2 -SnO2), Colorona marketed by Merck (Mica-TiO2-Fe2O3).

[0046] 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.;

[0047] Still as an example of nacres, we can also cite particles comprising a borosilicate substrate coated with titanium oxide.

[0048] Particles with a glass substrate coated with titanium oxide are notably sold under the name METASHINE MC1080RY by the company TOYAL.

[0049] Finally, as examples of nacres, mention may also be made of polyethylene terephthalate flakes, in particular those marketed by the company Meadowbrook Inventions under the name Silver IP 0.004X0.004 (silver flakes). Multilayer pigments based on synthetic substrates such as alumina, silica, calcium and sodium borosilicate or calcium and aluminum borosilicate, and aluminum may also be considered.

[0050] 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.

[0051] 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.

[0052] These particles can have various shapes, in particular being platelet-shaped or globular, in particular spherical.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] The reflective material may comprise a layer of metal or a metallic material.

[0058] Reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] Examples include aluminum, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] The pigments may be dispersed in the composition using a dispersing agent.

[0067] 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 physically or chemically attach to the surface of the pigments. These dispersants also have at least one functional group compatible or soluble in the continuous medium. In particular, esters of 12-hydroxystearic acid in particular and of C8 to C2o fatty acid and of polyol 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 their mixtures are used.

[0068] 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.

[0069] The pigments used in the composition may be surface-treated with an organic agent.

[0070] 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; metal alkoxides; polyethylene; (meth)acrylic polymers, for example polymethylmethacrylates; polymers and copolymers containing acrylate units; alkanoamines; silicone compounds, for example silicones, in particular polydimethylsiloxanes; fluorinated organic compounds, for example perfluoroalkyl ethers; fluorosilicon compounds.

[0071] 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.

[0072] 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. art or found as such in commerce.

[0073] Preferably, the surface-treated pigments are covered by an organic layer.

[0074] 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.

[0075] 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.

[0076] Preferably, an organic agent covalently bound to the pigments will be used.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] The dispersing agent(s) may therefore have a silicone backbone, such as silicone polyether and amino-silicone dispersants, different from the amino alkoxysilanes 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.

[0284] Non-amino silicones: Preferably, composition B further comprises at least one non-amino silicone, i.e. at least one silicone other than amino silicones.

[0285] In a manner known per se, the term "silicone" denotes all organosilicon polymers or oligomers with a linear or cyclic, branched or crosslinked structure, of variable molecular weight, obtained by polymerization and / or by polycondensation of suitably functionalized silanes, and consisting essentially of a repetition of main units in which the silicon atoms are linked together by oxygen atoms (siloxane bond -Si-O-Si-), optionally substituted hydrocarbon radicals being directly linked via a carbon atom to said silicon atoms.

[0286] Amino silicone means any silicone comprising at least one primary, secondary, tertiary amine group and / or at least one quaternary ammonium group.

[0287] The non-amino silicones according to the invention are different from the polymers P described previously and from the alkoxysilanes and their oligomers described below.

[0288] The non-amino silicones that may be used may be volatile or non-volatile.

[0289] The non-amino silicones that can be used can be soluble or insoluble in composition B according to the invention; they can be in the form of oil, wax, resin or gum; silicone oils and silicone resins are preferred.

[0290] Silicones are notably described in detail in the work of Walter NOLL "Chemistry and Technology of Silicones" (1968), Academie Press.

[0291] The volatile silicones may be chosen from those having a boiling point between 60 and 260°C (at atmospheric pressure), more particularly from:

[0292] i) cyclic polydialkylsiloxanes comprising from 3 to 7 silicon atoms, preferably 4 to 5, such as - octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane. Examples include products marketed under the name "VOLATILE SILICONE 7207" by UNION CARBIDE or "SILBIONE 70045 V 2" by RHODIA, "VOLATILE SILICONE 7158" by UNION CARBIDE, "SILBIONE 70045 V 5" by RHODIA. - cyclocopolymers of the dimethylsiloxane / methylalkylsiloxane type with structure We can cite the "VOLATILE SILICONE FZ 3109" marketed by the company UNION CARBIDE. - mixtures of cyclic silicones with organic compounds derived from silicon, such as the mixture of octamethylcyclotetrasiloxane and tetratrimethylsilyl-pentaerythritol (50 / 50) and the mixture of octamethylcyclotetrasiloxane and oxy-l,l'-(hexa-2,2,2',2',3,3'-trimethylsilyloxy) bis-neopentane;

[0293] ii) linear polydialkylsiloxanes having 2 to 9 silicon atoms, which generally have a viscosity less than or equal to 5.106 m2 / s at 25°C, such as decamethyltetrasiloxane. Other silicones in this class are described in the article published in Cosmetics and toiletries, Vol. 91, Jan. 76, p. 27-32 - TODD & BYERS "Volatile Silicone fluids for cosmetics"; we can cite the product marketed under the name "SH 200" by the company TORAY SILICONE.

[0294] Among the non-volatile silicones, mention may be made, alone or as a mixture, of polydialkylsiloxanes and in particular polydimethylsiloxanes (PDMS), polydiarylsiloxanes, polyalkylarylsiloxanes, silicone gums and resins, as well as organo-polysiloxanes (or organomodified polysiloxanes, or organomodified silicones) which are polysiloxanes comprising in their structure one or more organofunctional groups, generally attached via a hydrocarbon group, and preferably chosen from aryl groups, alkoxy groups and polyoxyethylenated or polyoxypropylenated groups.

[0295] The organomodified silicones may be polydiarylsiloxanes, in particular polydiphenylsiloxanes, and polyalkylarylsiloxanes functionalized by the organofunctional groups mentioned above. The polyalkylarylsiloxanes are particularly chosen from polydimethyl / methylphenylsiloxanes, linear and / or branched polydimethyl / diphenylsiloxanes.

[0296] Among the organomodified silicones, we can cite organopolysiloxanes comprising: - polyoxyethylene and / or polyoxypropylene groups possibly comprising C6-C24 alkyl groups such as dimethicone copolyols, and in particular those marketed by the company DOW CORNING under the name DC 1248 or SILWET® L 722, L 7500, L 77, L 711 oils from UNION CARBIDE; or alkyl(C12)-methicone-copolyols, and in particular those marketed by DOW CORNING under the name Q2-5200; - thiol groups, such as the products marketed under the names “GP 72 A” and “GP 71” from GENESEE; - alkoxylated groups, such as the product marketed under the name "SILICONE COPOLYMER F-755" by SWS SILICONES and ABIL WAX® 2428, 2434 and 2440 by the company GOLDSCHMIDT; - hydroxyl groups, such as polyorganosiloxanes with hydroxyalkyl function; - acyloxyalkyl groups such as the polyorganosiloxanes described in patent US-A-4957732. - anionic groups of the carboxylic acid type, as for example described in EP186507, or of the alkyl-carboxylic type such as the product X-22-3701E from the company SHIN-ETSU; or of the 2-hydroxyalkylsulfonate or 2-hydroxyalkylthiosulfate type, such as the products marketed by the company GOLDSCHMIDT under the names "ABIL® S201" and "ABIL® S255".

[0297] The silicones may also be chosen from polydialkylsiloxanes, among which mention may be made mainly of polydimethylsiloxanes with trimethylsilyl end groups. Among these polydialkylsiloxanes, mention may be made of the following commercial products: - SILBIONE® oils of the 47 and 70 047 series or MIRASIL® oils marketed by RHODIA such as, for example, oil 70 047 V 500 000; - MIRASIL® series oils marketed by RHODIA; - DOW CORNING 200 series oils such as DC200 with a viscosity of 60,000 mm2 / s; - VISCASIL® oils from GENERAL ELECTRIC and certain oils from the SF series (SF 96, SF 18) from GENERAL ELECTRIC.

[0298] Mention may also be made of polydimethylsiloxanes with dimethylsilanol end groups known as dimethiconol (CTFA), such as the oils of series 48 from the company RHODIA.

[0299] In this class of polydialkylsiloxanes, we can also cite the products marketed under the names "ABIL WAX® 9800 and 9801" by the company GOLDSCHMIDT which are polydialkyl (C1-C20) siloxanes.

[0300] Products which can be used more particularly in accordance with the invention are mixtures such as:

[0301] - mixtures formed from a polydimethylsiloxane hydroxylated at the end of chain, or dimethiconol (CTFA) and a cyclic polydimethylsiloxane also called cyclomethicone (CTFA) such as the product Q2-1401 marketed by the company DOW CORNING.

[0302] The polyalkylarylsiloxanes are particularly chosen from polydimethyl / methylphenylsiloxanes, linear and / or branched polydimethyl / diphenylsiloxanes with a viscosity ranging from 1.10-5 to 5.10-2m2 / s at 25°C.

[0303] Among these polyalkylarylsiloxanes, we can cite the products marketed under the following names: - SILBIONE® oils from the 70 641 series from RHODIA; - oils from the RHODORSIL® 70 633 and 763 series from RHODIA; - DOW CORNING 556 COSMETIC GRAD FLUID oil from DOW CORNING; - BAYER PK series silicones such as PK20; - BAYER PN and PH series silicones such as PN1000 and PH1000 products - certain oils from the GENERAL ELECTRIC SF series such as SF 1023, SF 1154, SF 1250, SF 1265.

[0304] Silicones can also be chosen from silicone resins. Generally, the term "resin" means a compound whose structure is three-dimensional. "Silicone resins" are also called "silicone resins" or "siloxane resins". Thus, for the purposes of the present invention, a polydimethylsiloxane is not a silicone resin.

[0305] The silicone resin(s) according to the invention may be chosen from silicone resins having a molecular weight of between 300 and 100,000 g / mol, preferably between 300 and 50,000 g / mol, more preferably between 300 and 30,000 g / mol. The term "molecular weight" means average molecular weight (Mw).

[0306] The nomenclature of silicone resins (also called siloxane resins or silicone resins) is known as "MDTQ", the resin being described according to the different siloxane monomeric units that it comprises, each of the letters "MDTQ" characterizing a type of unit.

[0307] The letter “M” represents the Monofunctional unit of formula RlR2R3SiOi / 2, the silicon atom being linked to a single oxygen atom in the polymer comprising this unit.

[0308] The letter “D” signifies a Difunctional unit RlR2SiO2 / 2 in which the silicon atom is linked to two oxygen atoms

[0309] The letter “T” represents a Trifunctional unit of formula RlSiO3 / 2.

[0310] Such resins are described for example in “Encyclopedia of Polymer Science and Engineering, vol. 15, John and Wiley and Sons, New York, (1989), p. 265-270, and US 2,676,182, US 3,627,851, US 3,772,247, US 5,248,739 or even US 5,082,706, US 5,319,040, US 5,302, 685 and US 4,935,484.

[0311] In the M, D, T units defined above, R, namely RI, R2 and R3, represents a hydrocarbon radical (in particular alkyl) having from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or even a hydroxyl group.

[0312] Finally, the letter “Q” signifies a Tetrafunctional SiO4 / 2 unit in which the silicon atom is linked to four oxygen atoms themselves linked to the rest of the polymer.

[0313] Various silicone resins with different properties can be obtained from these different units, the properties of these polymers varying according to the type of monomers (or units), the nature and number of the radical R, the length of the polymer chain, the degree of branching and the size of the pendant chains.

[0314] As silicone resins which can be used in composition B according to the invention, it is possible to use, for example, silicone resins of type MQ, type T or type MQT.

[0315] MQ resins: As an example of MQ type silicone resins, mention may be made of alkylsiloxy-silicates of formula [(Rl)3SiOi / 2]x(SiO2)y (MQ units) in which x and y are integers ranging from 50 to 80, and such that the RI group represents a radical as defined previously, and preferably is an alkyl group having from 1 to 8 carbon atoms, or a hydroxyl group, preferably a methyl group.

[0316] As an example of solid silicone resins of the MQ type of the trimethylsiloxy-silicate type, we can cite those marketed under the reference SR1000®, E 1 170-002® or SS 4230® by the company General Electric, under the reference TMS 803®, WACKER 803® and 804® by the company Wacker, under the name "KF-7312J®" by the company Shin-Etsu, "DC 749®", "DC 593®" by the company Dow Corning, under the name Silsoft 74 by the company Momentive Performance Materials.

The preparation of such resins is described in particular in patent US5817302.

[0318] Resins T: As an example of T-type silicone resins, mention may be made of polysilsesquioxanes of formula (RSiO3 / 2)x (T units) in which x is greater than 100 and such that the R group is an alkyl group having from 1 to 10 carbon atoms, said polysilsesquioxanes being able to further comprise Si-OH terminal groups.

Marketed under the name Tarox Iron Oxide R-516 HP by the company Titan Kogyo; 3. Marketed under the name Xiameter PMX-1501 Fluid by the Dow company. Protocols:

[0503] PI Protocol: The coloring composition B according to the invention is applied with the finger to a lock of dry natural brown hair (tone height 4), at a rate of 0.6 g of composition per gram of hair.

[0504] The lock of hair is left for 2 minutes at room temperature. The lock of hair is not rinsed.

[0505] The lock of hair is then dried with a hairdryer for 2 minutes.

[0506] The coloration obtained (at To) is then evaluated according to the protocol below.

[0507] The lock of hair thus colored is then subjected to shampooing in order to evaluate the tenacity (remanence, resistance) of the coloring obtained, according to the following shampooing protocol repeated 3 times: The hair strand is washed using a standard shampoo (Garnier Ultra Doux), at a rate of 0.4 g of shampoo per gram of hair. The hair strand is then rinsed, combed, and dried with a hairdryer.

[0508] The coloring obtained after the 3 shampoos (at T3S) is then evaluated according to the protocol below.

[0509] Protocol P2: The coloring composition B according to the invention is applied with the finger to another lock of natural dry brown hair (tone height 4), at a rate of 0.6 g of composition per gram of hair.

[0510] The lock of hair is left for 2 minutes at room temperature. The lock of hair is not rinsed.

[0511] The lock of hair is then dried with a hairdryer for 2 minutes.

[0512] The coloration obtained (at To) is then evaluated according to the protocol below.

[0513] 30 minutes after application of the coloring composition, and once the coloring has To be evaluated, composition Di is applied to the entire strand of hair using a brush, at a rate of 2g of composition D per gram of hair.

[0514] The lock of hair is left for 5 minutes at room temperature, then the lock of hair is rinsed.

[0515] Finally, the lock of hair is washed using a standard shampoo (Garnier Ultra Doux), at a rate of 0.4 g of shampoo per gram of hair. The lock of hair is then rinsed, combed and dried with a hairdryer.

[0516] The removal of the coloration after the application of the DI composition (at TDi) is then evaluated according to the protocol below. Results :

[0517] The color persistence of the highlights after shampooing was evaluated in the CIE L*a*b* system, using a Minolta Spectrophotometer CM3600A colorimeter (illuminant D65, angle 10°, specular component included).

[0518] 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.

[0519] The persistence of the color is evaluated by the AE color difference between the colored strands before shampooing, then after having undergone 3 shampoos according to the protocol described above. The lower the AE value, the more persistent / resistant the color is. to shampoos.

[0520] The value of AE is calculated according to the following equation: as -

[0521] In this equation, for the persistence of the coloring to shampoos, L*, a*, b* represent the values ​​measured at T3S after coloring the hair and after having undergone the 3 shampoos, and Lo*, a0*, b0* represent the values ​​measured at To after coloring the hair but before the 3 shampoos.

[0522] Respectively, the removal of the coloration on the hair is evaluated by the color difference AE between the colored strands before application of the composition Dp then after the application of the composition Di according to the protocol described above. The greater the value of AE, the more the coloration obtained by the application of the composition B has been removed.

[0523] The value of AE is calculated according to the following equation: A g - ¥7^3

[0524] In this equation, for the persistence of the coloring with composition Dl, L*, a*, b* represent the values ​​measured at TD[ after the application of composition Db and Lo*, ao*, b0* represent the values ​​measured at To after coloring the hair but before the application of composition Dp

[0525] The color difference AE' between the hair before coloring, then after the application of composition Dl is also evaluated: the lower the value of AE', the more effective the "makeup removal" is (i.e. composition B has been eliminated) and the more the hair regains its natural color.

[0526] The value of AE' is calculated according to the following equation:

[0527] In this equation, L*, a*, b* represent the values ​​measured at TD[ after the application of composition Dp and Lo*, ao*, b0* represent the values ​​measured before the application of composition B (i.e. control).

[0528] The results obtained with the PI and P2 protocols are grouped in the table below:

[0529] [Tables3] Wicks TL* a* b* AE AE' Control (HT 4 untreated) - 20.33 2.97 2.95 - - Protocol PI To 26.65 18.2 14.23 - - Tss 26.95 16.92 13.25 1.64 - Protocol P2 To 26.33 17.94 14 - - td1 20.92 3.28 3.38 18.89 0.79

[0530] The lock of hair treated according to the PI protocol has a low AE value. The colored coating of the keratin fibers obtained with the application of the coloring composition B of the process according to the invention thus has good persistence to shampoos.

[0531] Furthermore, the lock of hair treated according to protocol P2 has a high AE value showing very good color removal, and a very low AE' value showing a return to natural coloring. Thus, the colored coating of the keratin fibers obtained with the application of coloring composition B, was indeed eliminated with the application of composition DI of the process according to the invention.
