Description

The present invention relates to compositions intended for the make-up and / or care of human keratin materials, such as skin, lips, keratin fibers such as: eyelashes in particular, comprising polymer particles, at least one hydrocarbon oil and at least one particular pigment. It also relates to a process for makeup and / or care of human keratin materials, such as skin, lips but also keratin fibers such as eyelashes, eyebrows, of applying the composition according to the invention. For several years, it is sought to obtain makeup compositions that have improved hold. The tenacity of the deposit, on the one hand, avoids having to reapply the composition too often and, on the other hand, it reduces the transfers on supports with which the masked areas come into contact (clothes, cups, etc.) or else their elimination by the action of external agents (sebum, food, rain, etc.).

This result is achieved by using a film-forming agent, often a polymer in a solubilized or dispersed form in one of the phases of the composition. Said agent allows the latter, once applied, to form after drying, a more cohesive and tenacious film on the support. One of the problems encountered with such film-forming agents lies in the fact that the compositions containing them give a deposit which, once dry, significantly loses its gloss. However this can be perceived as a disadvantage in the case of certain applications where not only toughness but also brightness are desired. These deposits are also often uncomfortable and cause feelings of dryness and tugging.It is therefore not uncommon to apply a second composition on the first which brings the behavior of the color, either spontaneously (with the application of a lip balm) is recommended with the first composition (with the application of a so-called "top coat" composition, in this case we speak for all the two compositions, of "double gesture" compositions). This second composition, often transparent, brings both brilliance and comfort. These products represent a very clear improvement in the behavior of the composition and color on the lips, but their implementation is complex because of the need to implement two steps to obtain the result. It is therefore in search of compositions having improved hold, easy to apply and whose deposit is very bright, comfortable, without requiring the implementation of several successive compositions.

The subject of the invention is therefore a composition comprising particles of at least one polymer stabilized on the surface by a stabilizing agent; the polymer of the particles being a C 1 -C 4 alkyl (meth) acrylate polymer; the stabilizing agent being a polymer of isobornyl (meth) acrylate selected from isobornyl (meth) acrylate homopolymer and random copolymers of isobornyl (meth) acrylate and alkyl (meth) acrylate Cl-04 present in a weight ratio of isobornyl (meth) acrylate / C1-C4 alkyl (meth) acrylate greater than 4, at least one hydrocarbon-based oil, and at least one pigment selected from pure or composite metallic particles , optionally oxidized, the multilayer interference pigments, optionally coated with brightener (s) optics (s), and their mixture. The subject of the invention is also a process for making up and / or caring for keratinous substances, in particular the skin, the lips and the keratinous fibers, such as the eyelashes, the eyebrows, consisting of applying the said composition.

It has been found that the composition according to the invention gives very bright deposits.

The stabilizer is in contact with the surface of the polymer particles and thus makes it possible to stabilize these particles in part. surface, in particular for maintaining these particles in dispersion in the non-aqueous medium of the dispersion. According to a theory that can not limit the scope of the present invention, the inventors theorize that the surface stabilization of the C 1 -C 4 alkyl (meth) acrylate polymer particles results from an adsorption phenomenon of surface of the stabilizing agent on the C1-C4 alkyl (meth) acrylate polymer particles.

When the polymer particles are made into the composition in the form of a previously prepared dispersion, the oily medium of this polymer dispersion comprises a hydrocarbon oil. Reference may be made to what has been said above about this oil in terms of its nature. Advantageously, the hydrocarbon oil is apolar and preferably selected from hydrocarbon oils having from 8 to 16 carbon atoms, in particular apolar oils, described above. Preferentially, the hydrocarbon oil is isododecane. The polymer particles, in particular in the dispersion, preferably have an average size, especially in number, ranging from 50 to 500 nm, in particular ranging from 75 to 400 nm, and better still from 100 to 250 nm. In general, a dispersion of surface-stabilized polymer particles suitable for the invention may be prepared in the following manner, given by way of example. The polymerization can be carried out in dispersion, that is to say by precipitation of the polymer being formed, with protection of the particles formed with a stabilizer. In a first step, the stabilizing polymer is prepared by mixing the monomer (s) constituting the stabilizing polymer, with a radical initiator, in a solvent called synthetic solvent, and by polymerizing these monomers.

In a second step, the monomer constituting the polymer is added to the stabilizing polymer formed and the polymerization of these added monomers is carried out in the presence of the radical initiator. When the non-aqueous medium is a non-volatile hydrocarbon oil, the polymerization can be carried out in an apolar organic solvent (synthetic solvent), then the nonvolatile hydrocarbon oil (which must be miscible with the said synthesis solvent) is added and the synthetic solvent. A synthesis solvent is thus chosen such that the monomers of the stabilizing polymer and the radical initiator are soluble therein, and the polymer particles obtained therein are insoluble so that they precipitate during their formation.

In particular, the synthesis solvent can be chosen from alkanes such as heptane or cyclohexane. When the non-aqueous medium is a volatile hydrocarbon oil, the polymerization can be carried out directly in the said oil, which thus also acts as a synthesis solvent. The monomers must also be soluble there, as well as the radical initiator, and the polymer of the particles obtained must be insoluble there. The monomers are preferably present in the synthesis solvent, before polymerization, in a proportion of 5-20% by weight. All of the monomers may be present in the solvent before the start of the reaction, or a portion of the monomers may be added as the polymerization reaction progresses.

The radical initiator may be in particular azobisisobutyronitrile or tert-butylperoxy-2-ethylhexanoate. The polymerization can be carried out at a temperature ranging from 70 to 110 ° C. The polymer particles are surface-stabilized, when formed during the polymerization, by the stabilizing agent.

The stabilization can be carried out by any known means, and in particular by direct addition of the stabilizing agent, during the polymerization. The stabilizer is preferably also present in the mixture prior to polymerization of the monomers of the polymer of the particles. However, it is also possible to add it continuously, especially when the monomers of the polymer of the particles are also continuously added. It is possible to use from 10 to 30% by weight of stabilizer relative to the total weight of monomers used (stabilizer + polymer of the particles), and preferably from 15 to 25% by weight. The dispersion of polymer particles advantageously comprises from 30 to 65% by weight of solids, relative to the total weight of the dispersion, and preferably from 40 to 60% by weight.

Furthermore, the composition according to the invention advantageously comprises a content of surface-stabilized polymer particles, expressed as active ingredient, of between 5 and 55% by weight, preferably between 5 and 50% by weight, of preferably between 8 and 45% by weight, more particularly between 10 and 40% by weight, and even more preferably between 15 and 35% by weight, relative to the composition weight. Plasticizer According to one embodiment of the invention, the composition comprises at least one plasticizer. In the case where the polymer particles are made in the form of a dispersion, the plasticizer is then advantageously present in said oily dispersion. The plasticizer (s) may be chosen from n-butyl tri-citrate, tripropylene glycol monomethyl ether (INCI name: PPG-3 methyl ether), trimethyl pentaphenyl trisiloxane (sold under the name DOW CORNING PH-1555 HRI COSMETIC FLUID by Dow Corning). These plasticizers make it possible to improve the mechanical strength of the polymer film. The plasticizer may be present in a content ranging from 2 to 50% by weight, relative to the total weight of the polymer of the particles, preferably from 2 to 40% by weight and even more particularly below 20% by weight relative to the weight of the composition.

By "metal" is meant comprising, or consisting of, at least one metal, a metal alloy or a (poly) metal oxide.

For example, for a very bright rendering, a glass or metal substrate may be preferred. The interference pigment may comprise more than four layers of different refractive indices. The particle size of the multilayer interference pigment, given by the average particle size at half of the population, also called D50, is, for example, from 1 μm to 2000 μm, better still from 5 μm to 2000 μm. The coverage of the composition may be due essentially to the content of multilayer interference pigment. The multilayer interference pigments may be chosen from nacres, goniochromatic pigments and their mixture.

Such compounds are described in "Fluorescent Vishing Agent, Encyclopedia of Chemical Technology, Kirk-Othmer," Vol. 11, p. 227-241, 4th edition, 1994, VViley. Their use in cosmetics draws particular benefit from the fact that they consist of chemical compounds with fluorescent properties that absorb in the ultraviolet (maximum absorption at a wavelength of less than 400 nm) and re-emit energy through fluorescence for a wavelength between 380 and 830 nm. They can more particularly be defined as compounds which absorb substantially in the UVA between 300 and 390 nm and re-emit essentially between 400 and 525 nm.

Examples of such products include clays of the smectite family, as well as the vermiculite family, stevensite, chlorites. These clays can be of natural or synthetic origin. More particularly, there may be mentioned smectites such as saponites, hectorites, montmorillonites, bentonites, beidellite and in particular synthetic hectorites (also called laponites) such as the products sold by Rockwood Additives Limited under the names Laponite®. XLS, Laponite® XLG, Laponite® RD, Laponite® RDS, Laponite® XL21 (these products are sodium and magnesium silicates and especially sodium, lithium and magnesium silicates); bentonites, such as the product sold under the name Bentone HC by Rheox; magnesium and aluminum silicates, in particular hydrated silicates, such as the products sold by Vanderbilt Company under the name Veegum ultra, Veegum HS and Veegum DGT, or else calcium silicates and in particular the synthetic form sold by the company under the name Preferably, organophilic clays are used, more particularly modified clays, such as montmorillonite, bentonite, hectorite, attapulgite, sepiolite, and mixtures thereof. The clay is preferably a bentonite or a hectorite.

These clays are modified with a chemical compound selected from quaternary amines, tertiary amines, amino acetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates, amine oxides, and mixtures thereof. It is thus possible to mention the hectorites modified with a quaternary amine, more specifically with a halide, such as a chloride, of 0-10 to 022 fatty acid ammonium, such as hectorite modified with di-stearyl-dimethyl ammonium chloride. (CTFA name: Disteardimonium hectorite), such as, for example, that marketed under the name Bentone 38V®, Bentone 38V CG, Bentone EVV CE, by the company ELEMENTIS; stearalkonium Hectorites such as Bentone 27 V, mention may also be made of quaternium-18 bentonites such as those sold under the names Bentone 34 marketed by Elementis, Claytone Claytone 40, Tixogel VP by United catalyst by Southern Clay; stearalkonium bentonites such as those sold under the names Tixogel LG by United Catalyst, Claytone AF, Claytone APA by Southern Clay; 18-quaternium / benzalkonium bentonite such as those sold under the name Claytone HT by the company Southern Clay According to a preferred embodiment, the thickening agent is chosen from organophilic modified clays, in particular modified organophile hectorites, in particular by benzyldimethyl ammonium stearate chloride, or distearyl dimethyl ammonium chloride. According to a variant of the invention, the optionally modified clay content (expressed as active material) varies very particularly from 0.2 to 10% by weight, preferably from 0.5 to 5% by weight, relative to the weight of the composition. Ii) Potentially modified silicas One may also mention the fumed silica optionally treated with hydrophobic surface with a particle size of less than 1 .mu.m. It is indeed possible to chemically modify the surface of the silica, by chemical reaction generating a decrease in the number of silanol groups present on the surface of the silica. In particular, it is possible to substitute silanol groups with hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups may be: trimethylsiloxyl groups, which are especially obtained by treatment of fumed silica in the presence of hexamethyldisilazane. Silicas 17 thus treated are referred to as "Silica silylate" according to the CTFA (6th edition, 1995). They are, for example, sold under the references Aerosil R812® by the company Degussa, CAB-O-SIL TS-530® by the company Cabot, dimethylsilyloxyl or polydimethylsiloxane groups, which are in particular obtained by treatment of fumed silica in the presence of polydimethylsiloxane. or dimethyldichlorosilane. Silicas thus treated are called "Silica dimethyl silylate" according to the CTFA (6th edition, 1995). They are for example marketed under the references Aerosil R972®, and Aerosil R974® by the company DEGUSSA, CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by the company 10 CABOT. The hydrophobic fumed silica has in particular a particle size that can be nanometric to micrometric, for example ranging from about 5 to 200 nm. The composition according to the invention comprises at least silica airgel particles. Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized by sol-gel process in a liquid medium and then usually dried by extraction of a supercritical fluid, the most commonly used being supercritical CO2. This type of drying avoids the contraction of the pores and the material. The sol-gel process and the various dryings are described in detail in Brinker CJ, and Scherer G.VV., Sol-Gel Science: New York: Academic Press, 1990. The hydrophobic silica airgel particles used herein The invention has a specific surface area per unit mass (Sm) of from 500 to 1500 m 2 / g, preferably from 600 to 1200 m 2 / g and more preferably from 600 to 800 m 2 / g, and a size expressed as a volume average diameter. (D [0.5]) ranging from 1 to 1500 μm, more preferably from 1 to 1000 μm, preferably from 1 to 100 μm, in particular from 1 to 30 μm, more preferably from 5 to 25 μm, more preferably from 5 to 25 μm. 20 μm and even more preferably from 30 to 15 μm. According to one embodiment, the hydrophobic silica airgel particles used in the present invention have a size expressed in volume mean diameter (D [0.5]) ranging from 1 to 30 μm, preferably from 5 to 25 μm. better from 5 to 20 μm and even better from 5 to 15 μm. The specific surface area per unit mass can be determined by the BET nitrogen absorption method (BRUNAUER - EMMET - TELLER) described in "The Journal of the American Chemical Society", vol. 60, page 309, February 1938 and corresponding to the international standard ISO 5794/1 (Appendix D). The BET surface area corresponds to the total specific surface area of the particles under consideration. The silica airgel particle sizes can be measured by static light scattering using a MasterSizer 2000 commercial particle size analyzer from Malvern. The data is processed on the basis of Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" diameter of particles. This theory is particularly described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, VViley, New York, 1957.

According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface per unit mass (Sm) ranging from 600 to 800 m 2 / g and a size expressed as a mean diameter by volume (D [0.5]) ranging from 5 to 20 μm and even more preferably from 5 to 15 μm.

In the context of the present invention, this density can be assessed according to the following protocol, called the packed density: 40 g of powder are poured into a graduated test tube; then the specimen is placed on the STAV 2003 device from STAMPF VOLUMETER; the test piece is then subjected to a series of 2500 settlements (this operation is repeated until the difference in volume between two consecutive tests is less than 2%); then the final volume Vf of compacted powder is measured directly on the test piece. The packed density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm3 and m in g). According to a preferred embodiment, the hydrophobic silica airgel particles used in the present invention have a specific surface area per unit volume Sv of from 5 to 60 m 2 / cm 3, preferably from 10 to 50 m 2 / cm 3 and better from 15 to 40 m2 / cm3. The specific surface area per unit volume is given by the relationship: Sv = Sm x a where a is the packed density expressed in g / cm 3 and Sm is the specific surface area per unit mass expressed in m2 / g, as defined above. Preferably, the hydrophobic silica aerogel particles according to the invention have an oil absorption capacity measured at VVET POINT ranging from 5 to 18 ml / g, preferably from 6 to 15 ml / g and better still 8 to 12 ml / g. The absorption capacity measured at VVet Point, and denoted VVp, corresponds to the amount of oil that must be added to 100 g of particles to obtain a homogeneous paste. It is measured according to the so-called VVet Point method or method for determining the setting of powder oil described in standard NF T 30-022. It corresponds to the quantity of oil adsorbed on the available surface of the powder and / or absorbed by the powder by measuring the VVet Point, described below: A quantity m = 2 g of powder is placed on a glass plate and then the oil (isononyl isononanoate) is added dropwise. After addition of 4 to 5 drops of oil in the powder, mixing is carried out with a spatula and oil is added until the formation of oil and powder conglomerates. From this moment, the oil is added one drop at a time and then triturated with the spatula. The addition of oil is stopped when a firm and smooth paste is obtained. This paste should be spread on the glass plate without cracks or lumps. The volume Vs (expressed in ml) of oil used is then noted. The oil intake corresponds to the ratio Vs / m. The aerogels used according to the present invention are aerogels of hydrophobic silica, preferably of silylated silica (INCI name silica silylate). By "hydrophobic silica" is meant any silica whose surface is treated with silylating agents, for example by halogenated silanes such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes such as hexamethyldisiloxane, or silazanes, in order to functionalize the OH groups by Si-Rn silyl groups, for example trimethylsilyl groups.
