Abstract

The invention relates to a cosmetic product containing a first composition and a second composition, the first composition comprising a vinyl polymer containing units derived from carbosiloxane dendrimers and the second composition comprising a cosmetically acceptable medium. The invention also relates to a makeup process and to a makeup kit containing the said product. This product is in particular a lipstick, a mascara or a nail varnish.

Description

The present invention relates to a cosmetic product comprising at least two compositions that may be applied successively to the skin either of the face or of the body, to the lower and upper eyelids, to the lips and to the integuments, for instance the nails, the eyebrows, the eyelashes, or the hair. The present invention also relates to a process for making up the face and the body using these two compositions.

Each composition may be a foundation, a makeup rouge, an eyeshadow, a concealer product, a blusher, a loose or compacted powder, a lipstick, a lip balm, a lip gloss, a lip pencil, an eye pencil, a mascara, an eyeliner, a nail varnish, a body makeup product or a skin colouring product. One object of the present invention is to propose a composition that both has good staying power and is glossy.

Poor staying power may be reflected in particular by poor fastness of the colour and/or by poor staying power of the gloss. This poor staying power may be characterized by a modification of the colour (colour change or fading) generally following interaction with the sebum and/or sweat secreted by the skin in the case of a foundation or a makeup rouge, or interaction with saliva in the case of lipsticks, or a reduction in the gloss, in the case of a nail varnish. This obliges the user to reapply makeup very regularly, which may constitute a loss of time.

To obtain transfer-resistant products with good staying power, volatile oils or polymers dispersed in a volatile solvent are often used. However, these products are not sufficiently glossy. A cosmetic product comprising two compositions has thus been envisaged, a first containing a polymer dispersed in a volatile solvent, onto which is applied a glossy and greasy second composition (FR-A-2 823 101) . The colour fastness of the makeup obtained with these compositions is good, but the disappearance of the second composition in the course of the day when it is worn results in a loss of the gloss desired by the consumer. The company Kose moreover proposed in its patent application J-A-O 5 221 829 the use of a gel based on perfluorinated materials, which is applied to a film of lipstick so as to prevent it from transferring onto other surfaces, the gel being incompatible with the film of lipstick. Mention may also be made of patent application WO-A-97/17057, which describes a method for increasing the staying power and transfer resistance properties, which consists in applying two compositions one over the other. The composition to be applied has a global Hildebrand solubility parameter of less than 8.5 (cal/cm³)¹*, and the composition to be applied as topcoat must contain oils whose calculated partition coefficient ClogP is at least equal to 13.

Patent US-A-β 001 374 proposes a makeup system, which consists in using an alcohol-soluble and water-insoluble resin, which may be applied as a basecoat or as a topcoat, and which has the advantage of not staining an object placed in contact with the makeup and of being resistant to water and to rubbing, while at the same time having a certain level of gloss. However, this composition contains a water-soluble alcohol, in particular ethanol, which is a compound of irritant nature that dries out the skin and more especially the lips, and which is particularly uncomfortable when the skin or the lips are damaged.

Patent application WO 02/067 877 describes a method for improving the aesthetic properties of a transfer-resistant composition, which consists in applying a second composition over a film of transfer- resistant composition. The second composition should not interact chemically with the transfer-resistant composition so as not to impair its cosmetic properties. Certain products described in the said document have an unpleasant odour and are tacky. Other products are not sufficiently glossy.

The aim of the present invention is to propose a novel route for formulating a cosmetic product, in particular a makeup product, of the type comprising two compositions to be applied successively one after the other. This cosmetic product may advantageously have good gloss and/or staying power properties.

One subject of the present invention is thus a cosmetic product comprising a first composition and a second composition, the first composition containing at least one vinyl polymer containing units derived from carbosiloxane dendrimers, and the second composition, which is different from the first, comprising a cosmetically acceptable medium.

The product of the invention is in particular a makeup product for the skin, the nails or the hair.

The term "makeup product" means a product containing a colouring agent allowing the deposition of a colour onto a keratin material (the skin or the integuments) of a human being by applying to the keratin material products such as lipsticks, makeup rouges, eyeliners, foundations, self-tanning products or semi-permanent makeup products (tattoos) . The product according to the invention comprises at least two cosmetically acceptable compositions packaged separately or together in the same packaging article or in at least two separate packaging articles. Preferably, these compositions are packaged separately and advantageously in separate packaging articles. The subject of the present invention is thus, in particular, a cosmetic makeup product in the form of a lipstick, a foundation, a mascara, a makeup rouge, an eyeliner, a lipstick, a nail varnish, a product especially having care properties, a mascara, an eyeliner, a concealer product or a makeup product for the body (such as a tattoo) or for the hair.

A subject of the invention is also a makeup kit containing a cosmetic makeup product as defined above, in which the various compositions are packaged separately and are advantageously accompanied by suitable application means. These means may be fine brushes, coarse brushes, pens, pencils, felts, feathers, sponges, tubes and/or foam tips. The first composition of the product according to the invention may constitute a basecoat applied onto the keratin material, and the second composition a topcoat. However, it is possible to apply under the first coat an undercoat that may or may not have the constitution of the second coat.

It is also possible to deposit an overcoat onto the second coat, which may have a constitution identical to or different from that of the first coat. Preferably, the makeup obtained is a two-coat makeup. The second composition may also constitute a basecoat applied to the keratin material and the first composition a topcoat. In particular, the basecoat is a lipstick, a foundation, a mascara, a lip gloss, an eyeliner, a nail varnish, a nailcare product or a body makeup product, and the topcoat is a care or protective product. The invention also relates to a process for making up the skin and/or the lips and/or the integuments, which consists in applying a cosmetic product as defined above to the skin and/or the lips and/or the integuments. A subject of the invention is also a cosmetic process for caring for or making up human skin and/or lips and/or integuments, which consists in applying to the skin, the lips and/or the integuments a first coat of a first composition comprising a vinyl polymer containing units derived from carbosiloxane dendrimers, and then in applying, onto all or part of the first coat, a second coat of a second composition comprising a cosmetically acceptable medium.

This process may consist in applying to the human skin, lips and/or integuments a first coat of a first composition comprising at least one vinyl polymer containing units derived from carbosiloxane dendrimers, leaving the said first coat to dry, and then applying, onto all or part of the first coat, a second coat of a second composition comprising a cosmetically acceptable medium.

This process may also consist in applying to human skin, lips and/or integuments a first coat of a composition comprising a cosmetically acceptable medium, leaving the said first coat to dry and then applying, onto all or part of the first coat, a second coat of a composition comprising a vinyl polymer containing units derived from carbosiloxane dendrimers. The product according to the invention may be applied to the skin of either the face or the scalp and of the body, the lips, the inner edge of the lower eyelids, and the integuments, for instance the nails, the eyelashes, the hair, the eyebrows, or even body hair. The second composition may form patterns and may be applied with a pen, pencil or any other instrument (sponge, finger, fine brush, coarse brush or feather) . This makeup may also be applied onto makeup accessories, for instance false nails, false eyelashes or wigs, or alternatively, onto dots or patches that adhere to the skin or the lips (such as beauty spots) . A subject of the invention is also a made-up support comprising a first coat of a first composition comprising a vinyl polymer containing units derived from carbosiloxane dendrimers, and a second coat of a second composition comprising a cosmetically acceptable medium, the said first coat being applied to the support first or over all or part of the second coat.

This support may be in particular a hairpiece such as a wig, false nails or false eyelashes, or alternatively patches that adhere to the skin or the lips (such as beauty spots) .

The invention also relates to the cosmetic use of the cosmetic product defined above to improve the comfort properties, in particular the tack-proof and/or non-dehydrating and/or gloss and/or transfer and/or migration and/or staying power properties of the makeup on the skin and/or the lips and/or the integuments. Finally, a subject of the invention is the use of a cosmetic product comprising a first composition and a second composition, the first composition comprising a vinyl polymer containing units derived from carbosiloxane dendrimers as described below, and the second composition comprising a cosmetically acceptable medium, to give the skin and/or the lips and/or the integuments a comfortable and/or glossy and/or transfer-resistant and/or non-migrating and/or fast cosmetic makeup result.

A carbosiloxane dendrimer that contains a radical-polymerizable organic group may be represented by the following mean structural formulae:

The carbosiloxane dendrimer may be manufactured according to the process for manufacturing a branched silalkylene siloxane described in Japanese patent application Hei 9-171 154. For example, it may be produced by subjecting an organosilicon compound containing a hydrogen atom linked to a silicon atom, represented by the following general formula:

and an organosilicon compound containing an alkenyl group, to a hydrosilylation reaction. In the above formula, the organosilicon compound may be represented by 3-methacryloxypropyltris (dimethylsiloxy) silane, 3-acryloxypropyltris (dimethylsiloxy) silane and 4-vinylphenyltris (dimethylsiloxy) silane. The organosilicon compound that contains an alkenyl group may be represented by vinyltris (trimethylsiloxy) silane, vinyltris (dimethylphenylsiloxy) silane, and 5- hexenyltris (trimethylsiloxy) silane. The hydrosilylation reaction is performed in the presence of a chloroplatinic acid, a complex of vinylsiloxane and of platinum, or a similar transition metal catalyst. In the vinyl polymer that contains a dendrimer structure, the polymerization ratio between the components (A) and (B) , in terms of the weight ratio between (A) and (B) , may be within the range from 0/100 to 99.9/0.1 and preferably within the range from 1/99 to 99/1. A ratio between the components (A) and (B) of 0/100 means that the compound becomes a homopolymer of component (B) .

The vinyl polymer contains a carbosiloxane dendrimer structure and this polymer may be obtained by copolyraerization of the components (A) and (B) , or by- polymerization of the component (B) alone. The polymerization may be a free-radical polymerization or an ionic polymerization, but free-radical polymerization is preferred. The polymerization may be performed by bringing about a reaction between the components (A) and (B) in a solution for a period of from 3 to 20 hours in the presence of a radical initiator at a temperature of from 50⁰C to 150⁰C. A suitable solvent for this purpose is hexane, octane, decane, cyclohexane or a similar aliphatic hydrocarbon; benzene, toluene, xylene or a similar aromatic hydrocarbon; diethyl ether, dibutyl ether, tetrahydrofuran, dioxane or similar ethers; acetone, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone or similar ketones; methyl acetate, ethyl acetate, butyl acetate, isobutyl acetate or similar esters; methanol, ethanol, isopropanol, butanol or similar alcohols; octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, hexamethyldisiloxane, octamethyltrisiloxane or a similar organosiloxane oligomer. A radical initiator may be any compound known in the art for standard free-radical polymerization reactions. The specific examples of such radical initiators are 2, 2' -azobis (isobutyronitrile) , 2,2'- azobis (2-methylbutyronitrile) , 2,2' -azobis (2, 4- dimethylvaleronitrile) or similar compounds of azobis type; benzoyl peroxide, lauroyl peroxide, tert-butyl peroxybenzoate, tert-butyl peroxy-2-ethylhexanoate or a similar organic peroxide. These radical initiators may be used alone or in a combination of two or more. The radical initiators may be used in an amount of from 0.1 to 5 parts by weight per 100 parts by weight of the components (A) and (B) . A chain-transfer agent may be added. The chain-transfer agent may be 2- mercaptoethanol, butyl mercaptan, n-dodecyl mercaptan, 3-mercaptopropyltrimethoxysilane, a polydimethyl- siloxane containing a mercaptopropyl group or a similar compound of mercapto type; methylene chloride, chloroform, carbon tetrachloride, butyl bromide, 3- chloropropyltrimethoxysilane or a similar halogenated compound. In the manufacture of the polymer of vinyl type, after the polymerization, the residual unreacted vinyl monomer may be removed under conditions of heating under vacuum.

To facilitate the preparation of the mixture of the starting material of cosmetic products, the number-average molecular mass of the vinyl polymer containing a carbosiloxane dendrimer may be chosen within the range between 3000 and 2 000 000 and preferably between 5000 and 800 000. It may be a liquid, a gum, a paste, a solid, a powder or any other form. The preferred forms are solutions consisting of the dilution of a dispersion or of a powder in solvents.

The vinyl polymer may be a dispersion of a polymer of vinyl type having a carbosiloxane dendrimer structure in its side molecular chain, in a liquid such as a silicone oil, an organic oil, an alcohol or water.

The vinyl polymer having a carbosiloxane dendrimer structure in its side molecular chain, in this embodiment, is the same as that described above. The liquid may be a silicone oil, an organic oil, an alcohol or water. The silicone oil may be a dimethylpolysiloxane with the two molecular ends capped with trimethylsiloxy groups, a copolymer of methylphenylsiloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, a copolymer of methyl-3, 3, 3-trifluoropropylsiloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, or similar unreactive linear silicone oils, and also hexamethyl- cyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclo- hexasiloxane or a similar cyclic compound. In addition to the unreactive silicone oils, modified polysiloxanes containing functional groups such as silanol groups, amino groups and polyether groups on the ends or within the side molecular chains may be used.

The organic oils may be liquid paraffin, isoparaffin, hexyl laurate, isopropyl myristate, myristyl myristate, cetyl myristate, 2-octyldodecyl myristate; isopropyl palmitate, 2-ethylhexyl palmitate, butyl stearate, decyl oleate, 2-octyldodecyl oleate, myristyl lactate, cetyl lactate, lanolin acetate, stearyl alcohol, cetostearyl alcohol, oleyl alcohol, avocado oil, almond oil, olive oil, cocoa oil, jojoba oil, gum oil, sunflower oil, soybean oil, camellia oil, squalane, castor oil, mink oil, cottonseed oil, coconut oil, egg yolk oil, beef tallow, lard, polypropylene glycol monooleate, neopentyl glycol 2-ethylhexanoate or a similar glycol ester oil; triglyceryl isostearate, the triglyceride of a fatty acid of coconut oil, or a similar oil of a polyhydric alcohol ester; polyoxyethylene lauryl ether, polyoxypropylene cetyl ether or a similar polyoxyalkylene ether.

The alcohol may be any type that is suitable for use in combination with a cosmetic product starting material. For example, it may be methanol, ethanol, butanol, isopropanol or similar lower alcohols. A solution or a dispersion of the alcohol should have a viscosity within the range from 10 to 10⁹ mPa at 25°C. To improve the sensory use properties in a cosmetic product, the viscosity should be within the range from 100 to 5 x 10⁸ mPa.s. The solutions and dispersions may be readily prepared by mixing the vinyl polymer having a carbosiloxane dendrimer structure with a silicone oil, an organic oil, an alcohol or water. The liquids may be present in the step of polymerization of the polymer of vinyl type having a carbosiloxane dendrimer structure. In this case, the unreacted residual vinyl monomer should be completely removed by heat treatment of the solution or dispersion under atmospheric pressure or reduced pressure. In the case of a dispersion, the dispersity of the polymer of vinyl type may be improved by adding a surfactant. Such an agent may be hexyl- benzenesulfonic acid, octylbenzenesulfonic acid, decylbenzenesulfonic acid, dodecylbenzenesulfonic acid, cetylbenzenesulfonic acid, myristylbenzenesulfonic acid or anionic surfactants of the sodium salts of these acids; octyltrimethylammonium hydroxide, dodecyltrimethylammonium hydroxide, hexadecyltrimethyl- ammonium hydroxide, octyldimethylbenzylammonium hydroxide, decyldimethylbenzylammonium hydroxide, dioctadecyldimethylammonium hydroxide, beef tallow- trimethylammonium hydroxide, coconut oil- trimethylammonium hydroxide, or a similar cationic surfactant; a polyoxyalkylene alkyl ether, a polyoxyalkylenealkylphenol, a polyoxyalkylene alkyl ester, the sorbitol ester of polyoxyalkylene, polyethylene glycol, polypropylene glycol, an ethylene oxide additive of diethylene glycol trimethylnonanol, and nonionic surfactants of polyester type, and also mixtures. In addition, the solvents and dispersions may be combined with iron oxide suitable for use with cosmetic products, or a similar pigment, and also zinc oxide, titanium oxide, silicon oxide, mica, talc or similar mineral oxides in powder form. In the dispersion, a mean oxide, titanium oxide, silicon oxide, mica, talc or similar mineral oxides in powder form. In the dispersion, a mean particle diameter of the polymer of vinyl type may be within a range of between 0.001 and 100 microns and preferably between 0.01 and 50 microns. The reason for this is that, outside the recommended range, a cosmetic product mixed with the emulsion will not have a nice enough feel on the skin or to the touch, or sufficient spreading properties or a pleasant feel. The vinyl polymer contained in the dispersion or the solution may have a concentration in the range between 0.1% and 95% by weight and preferably between 5% and 85% by weight. However, to facilitate the handling and the preparation of the mixture, the range should preferably be between 10% and 75% by weight.

The vinyl polymer may be one of the polymers described in the examples of patent application EP 0 963 751.

According to one embodiment, the vinyl polymer also comprises at least one organofluorine group.

Structures in which the polymerized vinyl units constitute the skeleton and carbosiloxane dendritic structures and also organofluorine groups are attached to side chains are particularly preferred.

The organofluorine groups may be obtained by replacing with fluorine atoms all or some of the hydrogen atoms of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, neopentyl, hexyl, cyclohexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, hexadecyl and octadecyl groups and other alkyl groups of 1 to 20 carbon atoms, and also alkyloxyalkylene groups of 6 to 22 carbon atoms.

Second composition The cosmetic product according to the invention comprises a second composition containing a cosmetically acceptable medium.

The second composition is advantageously chosen such that it improves at least one cosmetic property of the first composition, when it is applied alone to the said keratin material. The second composition may especially improve the comfort of the first composition or may reduce its tacky nature. The second composition may also be chosen such that the product, once applied to the keratin materials, has satisfactory gloss properties.

The first composition and/or the second composition may be chosen such that the product, once applied to the keratin materials, has satisfactory gloss properties. Gloss

The mean gloss of the product measured at 20⁰C, once the first composition and the second composition have been spread one over the other onto a support, may be advantageously greater than or equal to 30, preferably greater than or equal to 40, preferably greater than or equal to 50 and preferably greater than or equal to 60 out of 100. The term "mean gloss" denotes the gloss as may be conventionally measured using a gloss meter by the following method. The gloss of a deposit of the first composition alone, the gloss of a deposit of the second composition alone, or the gloss of a deposit of product according to the invention consisting of the superposition of deposits of the first composition and of the second composition may be measured.

A coat of between 50 μm and 150 μm in thickness of a composition is spread using an automatic spreader onto a Leneta brand contrast card of reference Form IA Penopac.

The coat of composition or of product covers at least the white background of the card. The deposit is left to dry for 24 hours at a temperature of 30⁰C, and the gloss at 20° is then measured on the white background using a Byk Gardner brand gloss meter of reference microTri-Gloss. This measurement (which is between 0 and 100) is repeated at least three times, and the mean gloss is the mean of the at least three measurements carried out. When it is desired to measure the gloss of the product according to the invention, a first coat of one of the two compositions is spread onto the contrast card, under the same conditions as described above. This first coat is left to dry for the required time, and a second coat of the other composition is then spread on top, under the same conditions as described above. The mean gloss of the first composition, or of the second composition, or of the product of the invention, measured at 20° is advantageously greater than or equal to 30, better still greater than or equal to 35, better still greater than or equal to 40, better still greater than or equal to 45, better still greater than or equal to 50 out of 100, better still greater than or equal to 55, better still greater than or equal to 60, better still greater than or equal to 65, better still greater than or equal to 70 or better still, greater than or equal to 75 out of 100. For certain compositions according to the invention, such as nail varnishes, the gloss measured at 20° may be greater than or equal to 70, or even 80, out of 100. Preferably, the mean gloss of the first composition, or of the second composition, or of the product of the invention, once spread onto a support, measured at 60° is greater than or equal to 50, better still greater than or equal to 60, better still greater than or equal to 65, better still greater than or equal to 70, better still greater than or equal to 75, better still greater than or equal to 80, better still greater than or equal to 85, or even better still greater than or equal to 90 out of 100. The mean gloss at 60° is measured under the same conditions as those described above for measuring the mean gloss at 20°. Staying power

The first composition and/or the second composition may also be chosen such that the product, once applied to the keratin materials, has satisfactory staying power properties.

In particular, the first composition preferably has a transfer index of greater than or equal to 80%, preferably greater than or equal to 85%, preferably greater than or equal to 90% and preferably greater than or equal to 95%.

The second composition may be chosen such that the transfer index of the product is greater than or equal to 80%, preferably greater than or equal to 85%, preferably greater than or equal to 90% and preferably greater than or equal- to 95%.

The transfer index of the deposit obtained with the composition according to the invention is determined according to the measuring protocol described below. A support (40 mm x 70 mm rectangle) consisting of an acrylic coating (hypoallergenic acrylic adhesive on polyethylene film sold under the name Blenderme ref. FH5000-55113 by the company 3M Sante) bonded onto a layer of polyethylene foam that is adhesive on the face opposite that onto which the adhesive tape is fixed (foam layer sold under the name RE40X70EP3 by the company Joint Technique Lyonnais Ind.) is prepared.

The L*₀a*₀b*o colour of the support, on the acrylic coating face, is measured using a Minolta CR 300 colorimeter.

The support thus prepared is preheated on a hotplate maintained at a temperature of 40⁰C such that the surface of the support is maintained at a temperature of 33⁰C ± 1°C. While leaving the support on the hotplate, the composition is applied over the entire non-adhesive surface of the support (i.e. to the surface of the acrylic coating) by spreading it out using a fine brush to obtain a deposit of about 15 μm of the composition, and it is then left to dry for 10 minutes.

After drying, the L*a*b* colour of the film thus obtained is measured.

The colour difference ΔE1 between the colour of the film relative to the colour of the naked support is then determined by means of the following relationship:

₌ V(L*-L₀*)2 + (a*-a_o*)2 + (b^*-b_o ^*)²

ΔE1

The support is then bonded via its adhesive face (adhesive face of the foam layer) to an anvil 20 mm in diameter and equipped with a screw pitch. A sample of the support/deposit assembly is then cut out using a punch 18 mm in diameter. The anvil is then screwed onto a press (Statif Manuel Imada SV-2 from the company Someco) equipped with a tensile testing machine (Imada DPS-20 from the company Someco) . A strip 33 mm wide and 29.7 cm long is drawn on a sheet of white photocopier paper with a basis weight of 80 g/m², a first line is marked 2 cm from the edge of the sheet, then a second line is marked 5 cm from the edge of the sheet, the first and second lines thus delimiting a box on the strip; a first mark and a second mark located in the strip at reference points 8 cm and 16 cm, respectively, from the second line is then applied. 20 μl of water are placed on the first mark and 10 μl of refined sunflower oil (sold by the company Lesieur) are placed on the second mark.

The sheet of white paper is placed on the bed of the press and the sample placed on the box of the strip of paper is then pressed at a pressure of about 300 g/cm² exerted for 30 seconds. Next, the press is lifted and the sample is again moved to just after the second line (i.e. next to the box), a pressure of about 300 g/cm² is again exerted and, once the contact has been made, the paper is moved in a rectilinear manner at a speed of 1 cπi/s, over the entire length of the strip such that the sample passes through the water and oil deposits. After removing the sample, some of the deposit has become transferred onto the paper. The L*¹, a*¹, b*¹ colour of the deposit remaining on the sample is then measured. The colour difference ΔE2 between the colour of the deposit remaining on the sample relative to the colour of the naked support is then determined by means of the following relationship:

ΔE2_s V(L*'-L₀*)² ₊ (a^*'-a_o ^*)^{2 +} (b^*'-b_o ^*)²

The transfer index of the composition, expressed as a percentage, is equal to the ratio: 100 x ΔE1/ΔE1.

The measurement is performed on 6 supports in succession and the transfer value corresponds to the mean of the 6 measurements obtained with the 6 supports.
