[0001] Cosmetic inverse emulsion composition comprising an oil, a surfactant, a filmforming polymer and a hydroxy acid
[0002] The present invention relates to a cosmetic composition in the form of a water-in-oil (W / O) emulsion, comprising a continuous fatty phase comprising at least one hydrocarbon oil with a refractive index greater than or equal to 1.4, an aqueous phase dispersed in the continuous fatty phase, at least one emulsifying surfactant with an HLB less than or equal to 8, at least one lipophilic film-forming polymer, at least one hydroxy acid, and at least one coloring material.
[0003] In the field of makeup products, the range of formulations is very wide. It ranges from very fluid liquid compositions to compositions in the form of molded solids, not to mention compacted or loose powders. Moreover, these compositions may be anhydrous or comprise an aqueous phase and be for example in emulsified form.
[0004] Despite this wide variety of dosage forms, each makeup field has developed its own particular characteristics, due to the constraints to which compositions are subjected once applied and the expected performance for compositions.
[0005] Thus, in the field of complexion makeup, formulas may be in the form of direct (oil-in- water) or inverse (water-in-oil) liquid emulsions. These formulations have made it possible to convey active ingredients more readily, in particular for enhanced care and hydration performance.
[0006] However, there is still a need for complexion makeup compositions, which are in inverse emulsion form, and which give the complexion a radiant, or even very radiant, effect, while retaining a good resistance.
[0007] An object of the present invention is to provide a solution to the problems mentioned above.
[0008] Indeed, the Applicant has developed water-in-oil (W / O) emulsions comprising at least one hydrocarbon oil with a refractive index greater than or equal to 1.4, at least one emulsifying surfactant with an HLB less than or equal to 8, at least one lipophilic film-forming polymer, at least one hydroxy acid, and at least one coloring material. Such emulsions make it possible to obtain foundations wherein the radiant effect can be maximized, while retaining a good resistance. Consequently, the present invention relates according to a first aspect to a cosmetic composition in water-in-oil (W / O) emulsion form, comprising: a) a continuous fatty phase comprising at least one hydrocarbon oil with a refractive index n greater than or equal to 1.4, b) an aqueous phase dispersed in the continuous fatty phase, c) at least one emulsifying surfactant with an HLB less than or equal to 8, d) at least one film-forming polymer, e) at least one hydroxy acid, and f) at least one coloring material.
[0009] Preferably, the composition according to the invention is substantially free from silicone oil. "Substantially free from silicone oil" means a composition comprising less than 2% by weight, preferably less than 1 % by weight, preferably less than 0.5% by weight, preferably less than 0.3% by weight of silicone oil relative to the total weight of the composition. Preferably, the composition according to the invention is completely free from silicone oil.
[0010] Despite the very low content, or even the complete absence of silicone oil, the compositions according to the invention have a very good resistance.
[0011] Although the composition is more particularly intended for complexion makeup, the composition according to the invention may also be applied on the skin, for example on the lips or cheekbones, as with a blush.
[0012] Furthermore, the composition according to the invention is typically a makeup composition for keratin materials, in particular for the complexion (therefore facial skin); it may also have a care component.

[0158] The term "pigments" should be understood to mean white or colored, mineral or organic particles, which are insoluble in an aqueous solution and are intended for coloring and / or opacifying the resulting deposit.
[0159] The pigments can be chosen from mineral pigments, organic pigments, and composite pigments (i.e. pigments with a mineral and / or organic material base). The pigments can be chosen from monochrome pigments, lacquers, nacres, optical-effect pigments, such as reflective pigments and goniochromatic pigments.
[0160] According to a particular embodiment, the pigments used according to the invention are chosen from mineral pigments. "Mineral pigment" means any pigment that complies with the definition in Ullmann’s Encyclopedia in the Inorganic Pigment chapter. Mention may be made, among the mineral pigments that can be used in the present invention, of zirconium or cerium oxides, along with zinc, iron (black, yellow or red) or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and iron blue, titanium dioxide, metallic powders such as aluminum powder and copper powder. The following mineral pigments can also be used: Ta2O5, Ti3O5, Ti2O3, TiO, ZrO2 in a mixture with TiO2, ZrO2, Nb2O5, CeO2, ZnS.
[0161] The size of the pigment that can be used within the scope of the present invention is in general greater than 100 nm and can range up to 10 pm, preferably from 200 nm to 5 pm, and more preferably from 300 nm to 1 pm. According to a particular embodiment of the invention, the pigments have a size characterized by a D
[0050] greater than 100 nm and can range up to 10 pm, preferably from 200 nm to 5pm, and more preferably from 300 nm to 1 pm. The sizes are measured by laser diffraction by means of a commercial MasterSizer 3000® granulometer from Malvern, making it possible to ascertain the granulometric distribution of all the particles over a wide range that can range from 0.01 pm to 1000 pm. The data are processed on the basis of the classic Mie scattering theory. This theory is the most adapted for size distributions ranging from submicron to multi-micron, and makes it possible to determine an "effective" diameter of particles. This theory is described particularly in the book by Van de Hulst, H.C., "Light Scattering by Small Particles", Chapters 9 and 10, Wiley, New York, 1957. D
[0050] represents the maximum size of 50% by volume of the particles.
[0162] In the context of the present invention, the mineral pigments are more particularly iron oxide and / or titanium dioxide.
[0163] As mineral pigments that can be used in the invention, nacres can also be cited. The term "nacres" should be understood to mean iridescent or non-iridescent colored particles of any shape, which are in particular produced by certain mollusks in their shell or else are synthesized and which exhibit a color effect by optical interference. The nacres can be selected from pearlescent pigments such as titanium mica coated with iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic coloring material, and pearlescent pigments based on bismuth oxychloride. They can also consist of mica particles at the surface whereof are superposed at least two successive layers of metal oxides and / or of organic coloring materials.
[0164] By way of example of nacres, mention can also be made of natural mica coated with titanium oxide, with iron oxide, with natural pigment or with bismuth oxychloride. The nacres may more particularly possess a yellow, pink, red, bronze, orange, brown and / or copper color or glint.
[0165] Among the pigments that can be used according to the invention, mention can also be made of those that have an optical effect that differs from a simple conventional hue effect, i.e. a unified and stabilized effect of the kind produced by conventional coloring materials, such as, for example, monochromatic pigments. For the purpose of the invention, "stabilized" means absence of an effect of variability of color with the angle of observation or in response to a temperature change. For example, this material may be selected from particles having a metallic glint, goniochromatic coloring agents, diffracting pigments, thermochromatic agents, optical brighteners, and also fibers, in particular of the interference type. Of course, these various materials can be combined so as to provide the simultaneous manifestation of two effects, or even a new effect in accordance with the invention.
[0166] According to a particular embodiment, the composition according to the invention comprises at least one non-coated pigment.
[0167] According to another particular embodiment, the composition according to the invention comprises at least one pigment coated with at least one lipophilic or hydrophobic compound. This type of pigment is particularly advantageous. Since they are treated by a hydrophobic compound, they manifest a preponderant affinity for an oily phase, which can then convey them. The coating can also comprise at least one additional non-lipophilic compound.
[0168] According to the invention, the "coating" of a pigment according to the invention generally denotes the full or partial surface treatment of the pigment by a surface agent, absorbed, adsorbed or grafted onto said pigment.
[0169] The surface-treated pigments can be prepared using chemical, electronic, mechanochemical or mechanical surface treatment techniques well known to a person skilled in the art. Commercial products can also be used.
[0170] The surface agent can be absorbed, adsorbed or grafted onto the pigments by means of solvent evaporation, chemical reaction or creation of a covalent bond. According to a variant, the surface treatment consists of a coating of the pigments. The coating can represent 0.1% to 20% by weight and particularly 0.5% to 5% by weight of the total weight of the coated pigment.
[0171] The coating can be carried out for example by adsorbing a liquid surface agent on the surface of the solid particles merely by mixing while stirring the particles and said surface agent, optionally heated, before incorporating the particles in the other ingredients of the makeup or care composition.
[0172] The coating can be carried out for example by means of a chemical reaction of a surface agent with the surface of the solid pigment particles and the creation of a covalent bond between the surface agent and the particles. This method is particularly described in patent US 4,578,266.
[0173] The chemical surface treatment can consist of diluting the surface agent in a volatile solvent, dispersing the pigments in this mixture, and then slowly evaporating the volatile solvent, such that the surface agent is deposited on the surface of the pigments.
[0174] According to a particular embodiment of the invention, the pigments may be coated according to the invention with at least one compound selected from silicone surfactants; fluorinated surfactants; fluorosilicone surfactants; metal soaps, n-acyl amino acids or salts thereof; lecithin and its derivatives; isopropyl triisostearyl titanate; isostearyl sebacate; plant or animal natural waxes; polar synthetic waxes; fatty esters; phospholipids; and mixtures thereof.
[0175] According to a particular embodiment, the coloring material is an organic, synthetic, natural pigment or pigment of natural origin.

[0178] The pigments can also be in the form of composite pigments as described in patent EP 1 184 426. These composite pigments can be composed in particular of particles including an inorganic core covered at least partially with an organic pigment and at least one binder for fixing the organic pigments to the core.
[0179] The pigment can also be a lacquer. The term lacquer means insoluble coloring materials adsorbed on insoluble particles, the assembly thus obtained remaining insoluble during use.

[0189] The hydrophobic pyrogenic silicas can be obtained by modifying the surface of the silica by a chemical reaction that generates a decrease in the number of silanol groups, with these groups in particular able to be substituted with hydrophobic groups. The hydrophobic groups may be:
[0190] - trimethylsiloxyl groups, particularly obtained by treating pyrogenic silica in the presence of hexamethyldisilazane. Silicas treated in this way are referred to as "Silica silylate" as per the CTFA (6th edition, 1995). They are for example sold under the references "Aerosil R812®" by Degussa, "CAB-O-SIL TS-530®" by Cabot;

They are generally synthesized by the sol-gel method in a liquid medium then dried usually via the extraction of a supercritical fluid, with the most commonly used being supercritical CO2. This type of drying makes it possible to prevent the contraction of the pores and of the material. The sol-gel method and the various dryings are described in detail in Brinker CJ., and Scherer G.W., Sol-Gel Science: New York: Academic Press, 1990.
[0193] Particles of hydrophobic silica aerogels modified on the surface by trimethylsilyl groups will preferably be used.

[0230] Compositions CC1 and C1 to C4 are evaluated for different parameters (see Table 2), including transfer resistance and gloss. Transfer resistance is evaluated as follows:
[0231] - Spreading of the composition on a contrast card at a thickness of 30 pm;
[0232] - Leave to dry at room temperature for at least 6 hours;
[0233] - Apply a piece of white Whypall type fabric to the deposit and place a 300g weight on top;
[0234] - Leave in place for 10s; - Remove the weight then carefully remove the piece of fabric;
[0235] - Evaluate the transfer of the deposit onto the fabric.
[0236] Results:
[0237] Score between 0 and 5 where: 0 = no transfer, and
[0238] 5 = all deposit is gone and has transferred to the fabric (full transfer). CONFORMITY: to pass, the composition must have a score between 0 and 3.5.
[0239] Gloss is evaluated as follows: Using a gloss meter (RHOPOINT Q 20 / 60 / 85° Gloss meter):
[0240] - Spreading of the composition on a contrast card at a thickness of 120 pm;
[0241] - Leave to dry at ambient temperature for at least 12 hours;
