Description

Title of the invention: Composition comprising at least one copolymer with acetoacetate functions and at least one alkoxysilane

[0001] The present invention relates to the field of cosmetic treatment of keratin fibers, preferably hair. It thus aims to propose new compositions comprising a particular copolymer in association with an alkoxysilane, which have excellent technical performances, in particular in terms of homogeneity and resistance of the coatings which they make it possible to obtain.

[0002] More specifically, the present invention relates to a composition intended for the treatment of human keratin fibers such as hair, comprising a particular copolymer formed from monomers carrying acetoacetate type functions in association with an alkoxysilane.

[0003] The present invention also relates to a method for treating keratin fibers such as hair using this composition, as well as a multi-compartment device comprising a first compartment containing a composition A1 comprising at least one alkoxysilane, and a second compartment containing a composition A2 comprising at least one particular copolymer formed from monomers carrying acetoacetate-type functions.

[0004] In the field of treatment of keratin fibers, particularly hair fibers, it is known to use one or more film-forming polymers in order to obtain a quality deposit of products on the fibers.

[0005] Document WO 2013 / 103528 proposes copolymers not organized in the particulate state, one of the monomers of which carries an acetoacetate function, in particular for hair applications. Document WO 2014 / 098052 proposes an acrylic resin emulsion for styling agents which has been stably dispersed by a poly(vinyl alcohol) resin. The compositions described in these documents, however, have unsatisfactory styling performance over time.

[0006] Furthermore, so-called hair makeup products 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 its hold in contact with water and a few shampoos. This requirement can be met in particular by using effective film-forming agents.

[0007] Thus, document FR 2 741 530 proposes for this purpose, for the temporary coloring of keratin fibers, the use of a dispersion of polymer particles film-forming agent 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.

[0008] 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.

[0009] There therefore remains a need to have compositions which make it possible to deposit a coating, colored or not, on keratin fibers, which is more homogeneous while being resistant to both shampoos and sebum, and to the various attacks that the hair may be subjected to such as brushing, perspiration and / or friction.

[0010] The present invention makes it possible to meet these needs.

[0011] The subject of the present invention is a composition, preferably cosmetic, comprising: (a) at least one alkoxysilane, and b) at least one CP copolymer obtained by the polymerization: - at least one monomer (B) 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 (Ci-C4)alkyl group, and * L represents a linear or branched (Ci-C6)alkylene or cycloalkylene group; and - at least one monomer (C) chosen from C1-C4 alkyl acrylates, C1-C4 alkyl methacrylates, silicone macromonomers, and mixtures thereof.

[0012] The application of such a composition to keratin fibers makes it possible to obtain particularly homogeneous coatings. It provides a coating 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 example blow-drying, brushing, rubbing and perspiration.

[0013] The present invention also relates to a method for treating keratin fibers comprising the application to said fibers of the above composition.

[0014] The present invention also relates to a multi-compartment device comprising a first compartment containing a composition A1 comprising at least one alkoxysilane, and a second compartment containing a composition A2 comprising at least one particular copolymer formed from monomers carrying acetoacetate type functions.

[0086] The pigments which can be used are in particular chosen from organic and / or mineral pigments known in the art, in particular those which are described in the Kirk-Othmer encyclopedia of chemical technology and in the Ullmann encyclopedia of industrial chemistry.

[0087] They can be natural, of natural origin, or not.

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.

[0096] The organic pigment may also be a lake. By lake is meant the dyes adsorbed on insoluble particles, the whole thus obtained remaining insoluble during use.

[0097] The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium and sodium borosilicate or sodium borosilicate. calcium and aluminum, and aluminum.

[0098] Among the colorants, we can cite carminic acid.

[0099] As examples of lacquers, we can cite the product known under the following name: D & C Red 7 (CI 15 850:1).

[0100] 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.

[0101] 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 pearlescent pigments, interference pigments or glitter.

[0102] 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. Examples of pearlescent pigments include Cellini pearlescent pigments marketed by BASF (Mica-TiO 2-lake), Prestige pearlescent pigments marketed by Eckart (Mica-TiO2), Prestige Bronze pearlescent pigments marketed by Eckart (Mica-Fe2O3), Syncrystal pearlescent pigments marketed by Eckart (Mica-TiO2-SnO2), Colorona pearlescent pigments marketed by Merck (Mica-TiO2-Fe2O3).

[0103] 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 tint notably marketed by BASF under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); mother-of-pearl with a copper sheen notably marketed by BASF under the name Copper 340A (Timica); mother-of-pearl with a red sheen notably marketed by MERCK under the name Sienna fine (17386) (Colorona); mother-of-pearl with a yellow sheen notably marketed by BASF under the name Yellow (4502) (Chromalite); mother-of-pearl with a red tint 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 pinkish-orange, golden-green mother-of-pearl notably marketed by MERCK under the name Indian summer (Xirona) and their mixtures.;

[0104] Still as an example of nacres, we can also cite particles comprising a borosilicate substrate coated with titanium oxide.

[0105] Particles with a glass substrate coated with titanium oxide are notably sold under the name METASHINE MC1080RY by the company TOYAL.

[0106] 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.

[0107] 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 state, 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.

[0108] 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 color or reflection, pink, red, bronze, orange, brown, gold and / or copper.

[0109] These particles can have various shapes, in particular being platelet-shaped or globular, in particular spherical.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] The reflective material may comprise a layer of metal or a metallic material.

[0115] Reflective particles are described in particular in documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Examples include aluminum, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] The pigments may be dispersed in the composition using a dispersing agent.

[0124] The dispersing agent serves to protect the dispersed particles against their 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 also have at least one functional group that is compatible or soluble in the continuous medium.In particular, esters of 12-hydroxystearic acid in particular and of C8 to C2o fatty acid and 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.

[0125] 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.

[0126] The pigments used in the composition may be surface-treated with an organic agent.

[0127] 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 chemical, electronic, electrochemical, mechanochemical 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 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.

[0128] 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.

[0129] 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.

[0130] Preferably, the surface-treated pigments are covered by an organic layer.

[0131] 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.

[0132] 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.

[0133] Preferably, an organic agent covalently bound to the pigments will be used.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] The dispersing agent(s) may therefore have a silicone backbone, such as silicone polyether and amino-silicone dispersants, different from the amino alkoxysilanes 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.

[0140] According to a particular embodiment, the dispersing agent(s) are of the amino-silicone type, different from the amino alkoxysilanes previously described in the application and are cationic.

[0141] Preferably, the pigment(s) is (are) chosen from mineral, mixed mineral-organic, organic pigments or special effect pigments.

[0142] In a variant of the invention, the pigment(s) according to the invention are organic pigments, preferably organic pigments surface-treated with an organic agent chosen from silicone compounds.

[0143] In another variant of the invention, the pigment(s) according to the invention are mineral pigments.

[0144] In another variant of the invention, the pigments according to the invention are special effect pigments, preferably pearlescent pigments, more preferably colored pearlescent pigments.

[0145] The composition according to the invention may comprise one or more direct dye(s).

[0146] By "direct dye" is meant natural and / or synthetic dyes, different from oxidation dyes. These are dyes which will diffuse superficially on the fiber. They can be ionic, for example cationic or anionic, or non-ionic.

[0147] 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; phthalocyanine dyes and natural direct dyes, alone or in the form of mixtures.

[0148] 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. The anionic dyes may be chosen from acid nitro direct dyes, acid azo dyes, acid azine dyes, acid triarylmethane dyes, acid indoamine dyes, acid anthraquinone dyes, indigoids and acid natural dyes.

[0293] Non-amino silicones: Preferably, the composition according to the present invention further comprises at least one non-amino silicone, i.e. one or more silicones other than amino silicones.

[0294] 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.

[0295] Amino silicone means any silicone comprising at least one primary, secondary, tertiary amine group and / or at least one quaternary ammonium group.

[0296] The non-amino silicones according to the invention are different from the polymers P, as well as from the non-amino alkoxysilanes and their oligomers described previously.

[0297] The non-amino silicones that may be used may be volatile or non-volatile.

[0298] The non-amino silicones that can be used can be soluble or insoluble in the composition according to the invention; they can be in the form of oil, wax, resin or gum; silicone oils and silicone resins are preferred.

[0299] Silicones are notably described in detail in the work of Walter NOLL "Chemistry and Technology of Silicones" (1968), Academie Press.

[0300] The volatile silicones can be chosen from those having a boiling point between 60 and 260°C (at atmospheric pressure), more particularly mainly among:

[0301] 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 chemical structure: i—D - ÏT---------D - D? —। CH, 1 0H, 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;

[0302] 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.

[0303] 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.

[0304] The organomodified silicones may be polydiarylsiloxanes, in particular polydiphenylsiloxanes, and polyalkylarylsiloxanes functionalized by the organofunctional groups mentioned above. The polyalkylarylsiloxanes are part particularly chosen from polydimethyl / methylphenylsiloxanes, linear and / or branched polydimethyl / diphenylsiloxanes.

[0305] Among the organomodified silicones, we can cite organopolysiloxanes comprising: - polyoxyethylene and / or polyoxypropylene groups optionally 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 the oils SILWET® L 722, L 7500, L 77, L 711 from the company UNION CARBIDE; or alkyl(C12)-methicone copolyols, and in particular those marketed by the company 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".

[0306] 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.

[0307] 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.

[0308] 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.

[0309] Products which can be used more particularly in accordance with the invention are mixtures such as:

[0310] - 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.

[0311] 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.

[0312] 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.

[0313] Silicones may 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.

[0314] 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).

[0315] 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.

[0316] 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.

[0317] The letter "D" means a Difunctional unit RlR2SiO2 / 2 in which the silicon atom is linked to two oxygen atoms

[0318] The letter “T” represents a Trifunctional unit of formula RlSiO3 / 2.

[0319] 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.

[0320] 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.

[0321] 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.

[0322] 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.

[0323] As silicone resins which can be used in the compositions according to the invention, it is possible to use, for example, silicone resins of type MQ, type T or type MQT.

[0324] 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.

[0325] 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.

[0326] As silicone resins comprising MQ siloxysilicate units, mention may also be made of phenylalkylsiloxysilicate resins, such as phenylpropyldimethylsiloxysilicate (Silshine 151® marketed by the company General Electric). The preparation of such resins is described in particular in patent US5817302.

[0327] T resins: As an example of T-type silicone resins, we can cite polysilse-quioxanes 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.

[0328] Preferably, polymethylsilsesquioxane resins in which R represents a methyl group can be used, such as, for example, those marketed: - by the company Wacker under the reference Resin MK® such as Belsil PMS MK®: polymer comprising repeating units CH3SiO3 / 2 (T units), which may also comprise up to 1% by weight of (CH3)2SiO2 / 2 units (D units) and having an average molecular weight of approximately 10,000 g / mol, or - by the company SHIN-ETSU under the references KR 220L® which are composed of T units of formula CH3SiO3 / 2 and have Si OH (silanol) end groups, under the reference KR-242A® which comprise 98% of T units and 2% of dimethyl D units and have Si-OH end groups or under the reference KR 251® comprising 88% of T units and 12% of dimethyl D units and have Si-OH end groups or - by the company GRANT INDUSTRIES under the name GRANRESIN PMSQ ID at 80% polymethylsilsesquioxane in isododecane.

[0329] MQT resins: As a resin comprising MQT units, those cited in document US 5,110,890 are known in particular.

[0330] A preferred form of MQT type resins are MQT-propyl resins (also called MQTPr). Such resins which can be used in the compositions according to the invention are in particular those described and prepared in application WO 2005 / 075542.
