    专利说明:

    The subject of the present invention is a composition for dyeing keratin fibers comprising at least one copolymer resulting from the polymerization of at least one crotonic acid monomer or derivative of crotonic acid and at least one vinyl ester monomer, at least one specific oil-in-water emulsion comprising silicones and at least one pigment, as well as a coloring process using said composition.
    In the field of dyeing keratin fibers, in particular human fibers, it is already known to color keratin fibers by different techniques from direct dyes or pigments for non-permanent dyes or dye precursors for permanent dyes.
    There are basically three types of hair coloring process:
    a) the 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;
    b) non-permanent, semi-permanent or direct coloring, which does not carry out the condensation, oxidative process and resists 4 or 5 shampoos; consists in dyeing keratin fibers with dye compositions containing direct dyes. These dyes are colored and coloring molecules with an affinity for keratin fibers.
    c) temporary coloring which gives rise to a modification of the natural color of the hair which takes from one shampoo to another and which serves to embellish or correct a shade already obtained. It can also be likened to a “makeup” process.
    For the latter type of coloring, it is known to use colored polymers formed by grafting one or more dyes of an azo, triphenylmethane, azine, indoamine or anthraquinone nature onto a polymer chain. These colored polymers are not entirely satisfactory, in particular as regards the uniformity of the coloration obtained, its resistance, without taking into account the problems linked to their manufacture and in particular to their reproducibility.
    Another coloring method is 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 pigment on the surface masks the natural color of the fiber. The use of pigment for coloring keratin fibers is for example described in patent application FR 2 741 530, these compositions, when applied to keratin fibers, have the drawback of transferring, that is to say, say to deposit at least in part, leaving traces, on certain supports with which they can be put in contact and in particular a garment or the skin. This results in poor performance of the applied film, requiring regular renewal of the application of the composition. In addition, the appearance of these unacceptable traces can dissuade some people from using this type of coloring.
    The compositions for temporary coloring and / or making up the hair can also lead to a touch of the hair which is not natural and / or is not cosmetic, the hair thus colored being able to lack softness and / or flexibility and / or individualization in particular.
    There therefore remains a need to obtain compositions for temporary coloring of keratin materials, in particular of the hair, which have the advantage of forming a deposit resistant to transfer, in particular which does not deposit, at least in part, on the supports with which they are brought into contact, such as the skin (hands and face in particular) and / or clothing.
    The invention aims to provide compositions which do not degrade keratin fibers, which do not alter their cosmetic properties such as softness and flexibility, keep the hair well individualized, not rough to the touch, while having properties resistance to transfer.
    This object is achieved with the present invention which relates to a composition for coloring keratin fibers, in particular human fibers, such as the hair, comprising:
    a) at least one copolymer resulting from the polymerization of at least one crotonic acid monomer or derivative of crotonic acid and at least one vinyl ester monomer,
    b) at least one oil-in-water emulsion having a particle size Dso of less than 350 nm and which comprises:
    a silicone mixture comprising (i) at least one polydialkylsiloxane with trialkylsilyl end groups, having a viscosity at 25 ° C ranging from 40,000 to 100,000 mPa.s and (ii) at least one amino silicone having a viscosity at 25 ° C ranging from 1000 to 15,000 mPa.s and an amine index ranging from 2 to 10 mg of KOH pal - gram of amino silicone;
    a surfactant mixture comprising one or more nonionic surfactants, said mixture having an HLB ranging from 10 to 16, and
    - water and
    c) at least one pigment.
    The invention also relates to a process for dyeing keratin fibers, especially human fibers, such as the hair, comprising the application to said fibers of a composition as defined above.
    By "at least one" means one or more.
    The composition according to the invention is preferably a cosmetic composition, preferably for the coloring of keratin fibers, in particular human keratin fibers such as the hair.
    It has been found that by using the coloring composition according to the invention, it was possible to improve the individualization of the hair, as well as to reduce the transfer. The fibers are also smoother to the touch, softer, more flexible and more easily disentangled.

    a step of mixing one or more polydialkylsiloxanes with trialkylsilyl end groups having a viscosity at 25 ° C ranging from 40,000 to 100,000 mPa.s, and one or more amino silicones having a viscosity at 25 ° C ranging from 1000 to 15,000 mPa.s and an amine index ranging from 2 to 10 mg of KOH per gram of amino silicone; at a temperature of 15 ° C to 40 ° C, in particular at 25 ° C, in order to obtain a fluid mixture of silicones; then
    a step of adding a surfactant mixture comprising one or more nonionic surfactants, said mixture having an HLB ranging from 10 to 16, to said fluid mixture of silicones, in order to obtain an emulsified mixture of silicone; then
    - a step of homogenizing said emulsified silicone mixture, followed by
    a step of adding demineralized water, preferably in stages, in order to obtain an oil-in-water emulsion having a particle size D50 of less than 350 nm.
    The preparation process can also include an additional step of adding one or more preservatives.
    The pH of the oil-in-water emulsion is generally between 4 and 6.
    The oil-in-water emulsion has a particle size D50 of less than 350 nm, in particular between 100 and 300 nm, better between 150 and 250 nm, or even between 160 and 200 nm.
    This size corresponds to the average hydrodynamic particle diameter (average hydrodynamic particle diameter). The particle size D50 is expressed in volume. It can be measured using a ZetaSizer device from Malvern, UK, Nano-ZS model, based on the “Photon Correlation Spectroscopy (PCS)” method.
    Method for measuring particle size
    The particle size of the emulsion is measured using a ZetaSizer device from Malvern, UK, Nano-ZS model, based on the "Photon Correlation Spectroscopy (PCS)" method.
    The particle size D50 is measured when the evaluation algorithm is “cumulants analysis”.
    0.5 g of the emulsion is placed in a 250 ml beaker, 100 ml of demineralized water are added and the mixture is mixed in order to obtain the test solution. The solution to be tested is put in the measuring tank (or cell) and introduced into the measuring device.
    Size D 50 corresponds to the value of particle diameter at 50% in cumulative distribution.
    For example, if D 50 = 170 nm, this means that 50% of the particles are larger than 170 nm, and that 50% of the particles are smaller than 170 nm.
    As a reminder, this distribution is in volume.
    Viscosity measurement method
    The viscosities, in particular of the silicone compounds, are measured at 25 ° C., 1 atm.
    To measure viscosities between 1000 and 40,000 mPa.s at 25 ° C, one can use an Anton Paar Rheometer, model MCR101, single gap cylinder geometry: CC27 spindle, shear speed 1 s' 1 for 2 minutes, at 25 ° vs.
    To measure viscosities between 40,000 and 100,000 mPa.s at 25 ° C, you can use an Anton Paar Rheometer, model MCR101, 25-6 cone (cone-plane geometry, 25 mm in diameter / 6 ° cone); Zero gap, shear speed 1 s' 1 for 2 minutes, at 25 ° C.
    Three measurements are made for each sample, and the viscosity value is taken at 60 seconds. MCR Rheometer Sériés products work according to the USP convention (US Pharmacopeia Convention, 912 - Rotational Rheometer methods).
    Amine index measurement method
    The amine index can be measured by acid-base titration, using a potentiometer [Make: Veego; VPT-MG model],
    0.6 g of the sample are placed in a 500 ml beaker and a toluenebutanol 1: 1 mixture is added, then mixed.
    The solution is titrated with 0.1N HCl solution. A determination of the zero value (Vbiank) is also made with the toluene-butanol mixture 1: 1 alone.
    The amine index is calculated using the formula:
    56.11 x (V - V Biank) x N / W mg KOH / g of sample.
    With V = volume of HCl required (in ml), VBiank = volume of HCl required for the zero value (in ml); N = normality of HCl, i.e. 0.1, and W = mass of the sample (in g).
    HLB values
    The term HLB relates to the hydrophilic-lipophilic balance of a surfactant. It can be measured experimentally or calculated.
    In the present application, the HLB values are the values at 25 ° C.
    The values of HLB can be calculated using the following equation: HLB = (E + P) / 5, in which E is the% by weight of oxyethylene and P is the% by weight of polyol, as described in the Griffin publication, J. Soc. Cosm. Chem. 1954 (vol.5, n ° 4), pp. 249-256.
    The HLB values can also be determined experimentally according to the book by Puisieux and Seiller, entitled Galenica 5: Dispersed systems - Volume I - Surfactants and emulsions - Chapter IV - Notions of HLB and critical HLB, pp. 153-194 - paragraph
    1.1.2. Determination of HLB experimentally, pp.164-180.
    Preferably, the HLB values obtained by calculation will be taken into account, in particular as follows: “calculated HLB” = 20 * (molar mass of the hydrophilic part / total molar mass).
    Thus, for an oxyethylenated fatty alcohol, the hydrophilic part corresponds to the oxyethylene units condensed on the fatty alcohol, and the "calculated HLB" then corresponds to "Griffin's HLB".
    For an ester or an amide, the hydrophilic part is generally defined as being beyond the carbonyl group, starting from or fatty chains.
    The HLB values of nonionic surfactants can also be calculated using Davies' formula, as described in Davies JT (1957), A quantitative kinetic theory of emulsion type, I. Physical chemistry of the emulsifying agent, Gas / Liquid and Liquid / Liquid Interface (Proceedings of the International Congress of Surface Activity): 426-438.
    According to this formula, the value of HLB is obtained by adding the hydrophilic / hydrophobic contribution linked to the groups constituting the surfactant:
    HLB = (number of hydrophilic groups) - n (number of groups per CH2 group) +7.
    The HLB values of certain cationic surfactants are given in Table IV, in “Cationic emulsifiers in cosmetics”, GODFREY, J. Soc. Cosmetic Chemists (1966) 17, ppl7-
    27.
    When two surfactants A and B, of known HLB, are mixed, the HLBmix corresponds to the HLB of the mixture and can be expressed by the following equation:
    HLBmîx = (WaHLBa + W b HLB b) / (W + W B) in which Wa is the amount (weight) 1 surfactant A and WB the amount of 2nd surfactant B and HLBA, HLB b are the values HLB of surfactant A and surfactant B.

    Examples of lacquers that may be mentioned include the product known under the following name: D & C Red 7 (CI 15 850: 1).
    The pigment can also be a special effect pigment. The term “special effect pigments” is intended to mean pigments which generally create a colored appearance (characterized by a certain shade, a certain liveliness and a certain clarity) which is not uniform and which varies according to the conditions of observation (light, temperature , angles of observation ...). They are therefore opposed to colored pigments which provide a uniform opaque, semi-transparent or transparent classic shade.
    There are several types of special effect pigments, those with a low refractive index such as fluorescent or photochromic pigments, and those with a high refractive index such as nacres, interference pigments or glitter.
    By way of examples of pigments with special effects, there may be mentioned 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 nacres sold by Engelhard (Mica-TiO2-lacquer), Prestige sold by Eckart (MicaTiO2), Prestige Bronze sold by Eckart (Mica-Fe2O3) Colorona sold by Merck (Mica-TiO2- Fe2O3).
    Mention may also be made of the gold-colored nacres sold in particular by the company ENGELHARD under the name of Brillant gold 212G (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne) ; the bronze nacres sold in particular by the company MERCK under the name Bronze fine (17384) (Colorona) and Bronze (17353) (Colorona) and by the company ENGELHARD under the name Super bronze (Cloisonne); the orange nacres sold in particular by the company ENGELHARD under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company MERCK under the name Passion orange (Colorona) and Matte orange (17449) (Microna); the brown-colored mother-of-pearl in particular sold by the company ENGELHARD under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); copper reflective nacres sold in particular by ENGELHARD under the name Copper 340A (Timica); mother-of-pearl with a red reflection, in particular sold by the company MERCK under the name Sienna fine (17386) (Colorona); the yellow-reflective nacres sold in particular by the company ENGELHARD under the name Yellow (4502) (Chromalite); the red-tinted pearls with a gold reflection, in particular sold by the company ENGELHARD under the name Sunstone G012 (Gemtone); pink mother-of-pearl in particular sold by ENGELHARD under the name Tan opal G005 (Gemtone); black mother-of-pearl with gold reflection in particular marketed by ENGELHARD under the name Nu antique bronze 240 AB (Timica), blue mother-of-pearl in particular marketed by MERCK under the name Matte blue (17433) (Microna), white mother-of-pearl with reflection silvery in particular marketed by the company MERCK under the name Xirona Silver and the pinkish orange-green pearl-green in particular marketed by the company MERCK under the name Indian summer (Xirona) and their mixtures.

    Particles with a glass substrate coated with titanium oxide are sold in particular under the name METASHINE MC1080RY by the company TOYAL.
    Finally, as examples of nacres, mention may also be made of polyethylene terephthalate flakes, in particular those sold by the company Meadowbrook Inventions under the name Silver IP 0.004X0.004 (silver flakes).
    One can also consider multilayer pigments based on synthetic substrates such as alumina, silica, calcium and sodium borosilicate or calcium and aluminum borosilicate, and aluminum.
    The pigments with special effects can also be chosen from reflective particles, that is to say in particular particles whose size, structure, in particular the thickness of the layer or layers which constitute it and their physical and chemical natures, and the surface condition, allow them to reflect the incident light. This reflection can, if necessary, 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, highlight points visible to the naked eye, that is that is, brighter dots that contrast with their surroundings by appearing to shine.
    The reflective particles can be selected so as not to significantly alter the coloring effect generated by the coloring agents associated with them and more particularly so as to optimize this effect in terms of color rendering. They can more particularly have a yellow or pink, red, bronze, orange, brown, gold and / or coppery color or reflection.
    These particles can have various shapes, in particular be in the form of platelets or globular, in particular spherical.
    The reflecting particles, whatever their shape, may or may not have a multilayer structure and, in the case of a multilayer structure, for example at least one layer of uniform thickness, in particular of a reflective material.
    When the reflecting particles do not have a multilayer structure, they can be composed for example of metal oxides, in particular titanium or iron oxides obtained by synthesis.
    When the reflecting particles have a multilayer structure, these can for example comprise a natural or synthetic substrate, in particular a synthetic substrate at least partially coated with at least one layer of a reflecting material in particular of at least one metal or metallic material . The substrate can be monomaterial, multimaterial, organic and / or inorganic.
    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.
    The reflective material may include a layer of metal or a metallic material.
    Reflective particles are described in particular in the documents
    JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710.
    Still by way of example of reflective particles comprising an inorganic substrate coated with a layer of metal, mention may also be made of particles comprising a borosilicate substrate coated with silver.
    Particles with a glass substrate coated with silver, in the form of platelets, are sold under the name MICROGLASS METASHINE REFSX 2025 PS by the company TOYAL. Particles with a glass substrate coated with a nickel / chromium / molybdenum alloy are sold under the name CRYSTAL STAR GF 550, GF 2525 by this same company.
    It is also possible to use particles comprising a metallic substrate such as silver, aluminum, iron, chromium, nickel, molybdenum, gold, copper, zinc, tin, magnesium, l steel, bronze, titanium, said substrate being coated with at least one layer of at least one metal oxide such as titanium oxide, aluminum oxide, iron oxide, oxide of cerium, chromium oxide, silicon oxides and their mixtures.
    By way of example, mention may be made of aluminum, bronze or copper powders coated with SiO2 marketed under the name VISIONAIRE by the company ECKART.
    Mention may also be made of pigments with an interference effect not fixed on a substrate, such as liquid crystals (Helicones HC from Wacker), holographic interference flakes (Geometry Pigments or Spectra f / x from Spectratek). Special effect pigments also include fluorescent pigments, whether they are substances which fluoresce in daylight or which produce ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments and quantum dots, marketed for example by Quantum Dots Corporation.
    Quantum dots are luminescent semiconductor nanoparticles capable of emitting, under light excitation, radiation having a wavelength between 400 nm and 700 nm. These nanoparticles are known from the literature. In particular, they can be synthesized according to the methods described for example in US 6,225,198 or US 5,990,479, in the publications cited therein, as well as in the following publications: Dabboussi BO et al (CdSe) ZnS core- shell quantum dots: synthesis and characterization of a size series of highly luminescent nanocrystallites Journal of phisical chemistry B, vol 101, 1997, pp 9463-9475. and Peng, Xiaogang et al, Epitaxial Growth of highly Luminescent CdSe / CdS core / shell nanocrystals with photostability and electronic accessibility Journal of the American Chemical Society, vol 119, N ° 30, pp 7019-7029.
    The variety of pigments which can be used in the present invention makes it possible to obtain a rich palette of colors, as well as specific optical effects such as metallic, interference effects.
    The size of the pigment used in the cosmetic composition according to the present invention is generally between 10 nm and 200 pm, preferably between 20 nm and 80 pm, and more preferably between 30 nm and 50 pm.
    The pigments can be dispersed in the product thanks to a dispersing agent.
    The dispersing agent is used to protect the dispersed particles against agglomeration or flocculation. This dispersing agent can 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 can cling physically or chemically to the surface of the pigments. These dispersants also have at least one functional group which is compatible or soluble in the continuous medium. In particular, esters of 12-hydroxy stearic acid in particular and of C8 to C20 fatty acid and of polyol such as glycerol, diglycerin, such as poly (12-hydroxystearic acid) stearate, are used. molecular weight of approximately 750g / mole such as that sold under the name Solsperse 21,000 by the company Avecia, the 2-polygyceryl dipolyhydroxystearate (name CTFA) sold under the reference Dehymyls PGPH by the company Henkel or else polyhydroxystearic acid such than that sold under the reference Arlacel P100 by the company Uniqema and their mixtures.

    Preferably, the surface-treated pigments are covered with an organic layer.
    The organic agent with which the pigments are treated can be deposited on the pigments by evaporation of solvent, chemical reaction between the molecules of the surfactant or creation of a covalent bond between the surfactant and the pigments.
    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 the fillers. This method is described in particular in US Patent 4,578,266.
    Preferably, an organic agent linked to the pigments will be used covalently.
