Description

Technical Field

[0001] This invention relates to the field of skin care and / or cosmetic treatments using keratin materials and aims to provide compositions that are more specifically designed for skin care and / or cosmetic treatments.

[0002] Skin is not a smooth, evenly colored surface; it has undulations and micro-undulations, such as pores, wrinkles, fine lines, spots, scars, and dry areas, which create a somewhat uneven surface. Often, this surface with irregularities forms a pleasing overall appearance, but the irregularities can occasionally make the surface seem unattractive.

[0003] Cosmetic and / or skincare compositions are commonly used to conceal, smooth, and / or unify skin imperfections such as pores, wrinkles, and / or fine lines and / or scars. Numerous solid or fluid, anhydrous or non-anhydrous formulations have been developed to date in this regard.

[0004] The application of cosmetic compositions such as foundation is the most effective way to enhance the appearance of irregular skin by concealing blemishes and skin discoloration, reducing the visibility of imperfections such as pores and wrinkles, and hiding spots and acne scars; in this respect, coverage is one of the main characteristics sought.

[0005] In the cosmetics industry, water-in-oil emulsions (also known as inverse emulsions) are particularly favored by consumers for their cosmetic properties, especially their post-application comfort in foundations, sunscreens, and moisturizers. This comfort is particularly evident in the non-greasy, powdery, and soft finish of the dried product. Compared to direct emulsions, these inverse emulsions also allow for the inclusion of higher concentrations of fillers and / or pigments, achieving good coverage and evenness during application. However, such compositions often suffer from the disadvantage of being difficult to stabilize.

[0006] Compositions used for cosmetic purposes on the skin, especially liquid foundations, typically contain volatile solvents such as cyclic volatile silicone oils, also known as cyclomethyl silicone oils, such as octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecylcyclohexasiloxane (D6). They provide a non-greasy, powdery, dry, yet soft and silky feel and facilitate product spread on the skin. However, cyclic volatile silicone oils are synthetic polymers of the non-biodegradable polyorganosiloxane type.

[0007] Compositions used for keratin materials such as skin care and / or cosmetics often contain additional fillers.

[0008] The term "filler" should be understood to mean any shape of colorless or white solid particles provided in an insoluble form and dispersed in the medium of the composition.

[0009] They are used as opacifiers and matting agents to impart a very special soft and silky feel, to give the composition a certain consistency or firmness and / or to give the cosmetic a soft and uniform feel.

[0010] Many care and / or cosmetic products contain organic fillers that are typically composed of synthetic polymer particles known as microplastics.

[0011] According to the European Chemicals Agency (ECHA), "microplastic fillers" should be understood as synthetic microparticles in solid form composed of polymers, having a size of less than 5 mm, and being insoluble and non-biodegradable. Microplastic fillers typically have a dry and soft feel.

[0012] There is still a need to find new formulations for the care and / or cosmetic application of keratin fibers, in the form of water-in-oil emulsions that are free of cyclic volatile silicone oils and microplastic fillers, with good coverage to cover imperfections for an even finish, good sensory properties (such as easy spreadability, non-greasy deposits after drying, a dry and soft powdery feel), and good stability in temperature stability tests.

[0013] Unexpectedly, the inventors have noticed that these purposes can be achieved using compositions in the form of water-in-oil emulsions for the care and / or cosmetic application of keratin materials, particularly skin, and which are contained in a physiologically acceptable medium:

[0014] a) At least one continuous oil phase comprising:

[0015] (i) at least one volatile alkane; and

[0016] (ii) at least one C 15 -C 19 Non-volatile mixtures of alkanes; and

[0017] (iii) at least one volatile noncyclic silicone oil; and

[0018] b) At least one aqueous phase dispersed in the oil phase;

[0019] c) At least hydrophobic silica aerogel particles; and

[0020] d) At least one silicone emulsifying surfactant with HLB ≤ 8.0;

[0021] The composition contains no cyclic volatile silicone oils or microplastic fillers.

[0022] This discovery forms the basis of this invention. Summary of the Invention

[0023] Therefore, the first subject of the present invention is a composition in the form of a water-in-oil emulsion for the care and / or cosmetic application of keratin materials, particularly skin, wherein the composition is contained in a physiologically acceptable medium:

[0024] a) At least one continuous oil phase comprising:

[0025] (i) at least one volatile alkane; and

[0026] (ii) at least one C 15 -C 19 Non-volatile mixtures of alkanes; and

[0027] (iii) at least one volatile noncyclic silicone oil; and

[0028] b) At least one aqueous phase dispersed in the oil phase;

[0029] c) At least hydrophobic silica aerogel particles; and

[0030] d) At least one silicone emulsifying surfactant with HLB ≤ 8.0;

[0031] The composition contains no cyclic volatile silicone oils or microplastic fillers.

[0032] The second subject of the present invention relates to a cosmetic method for applying keratin materials, particularly to skin such as the face, hands, eyelids, and cheeks, especially for makeup purposes, the cosmetic method comprising at least the step of applying a composition (as defined above) to the keratin material.

[0033] definition

[0034] In the context of this invention, the term "keratin material" specifically refers to skin, such as the face, body, hands, cheeks, eyelids, and the contours of the eyes.

[0035] The term “physiologically acceptable” means that it is compatible with skin and / or its coverings, has a pleasant color, smell and feel, and does not cause any unacceptable discomfort (tingling or tightness) that would easily prevent a consumer from using the composition.

[0036] "Water-in-oil emulsion" should be understood as a composition comprising an immiscible oil phase and an aqueous phase; the aqueous phase is dispersed in the oil phase in the form of droplets (described as continuous) in order to obtain a macroscopically homogeneous composition.

[0037] "Compositions free of cyclic volatile silicone oils" should be understood to mean any composition containing less than 1.0% by weight of cyclic volatile silicone oil relative to the total weight of the composition, actually less than 0.5% by weight, actually less than 0.1% by weight, or actually not containing any cyclic volatile silicone oil.

[0038] "Microplastic-free composition" should be understood to mean any composition containing less than 1.0% microplastics by weight relative to the total weight of the composition, actually less than 0.5% by weight, actually less than 0.1% by weight, or actually no microplastics at all.

[0039] "Oil" should be understood as referring to oil produced at room temperature (25°C) and atmospheric pressure (760 mmHg, i.e., 10). 5 The substance below (Pa) is a liquid fatty organic substance.

[0040] For the purposes of this invention, "volatile oil" should be understood to mean any oil that is capable of evaporating within one hour of contact with skin at room temperature and atmospheric pressure. Volatile oils are volatile cosmetic compounds that are liquid at room temperature and have a non-zero vapor pressure, particularly in the range of 0.13 Pa to 40,000 Pa (10⁻⁶ Pa). -3 Vapor pressures ranging from 1.3 Pa to 13,000 Pa (0.01 to 100 mmHg) and more particularly from 1.3 Pa to 1300 Pa (0.01 to 10 mmHg).

[0041] For the purposes of this invention, "volatile alkanes" should be understood to mean any alkane that is capable of evaporating within one hour of contact with skin at room temperature and atmospheric pressure. Volatile alkanes are volatile cosmetic compounds that are liquids at room temperature, and especially have a non-zero vapor pressure at room temperature and atmospheric pressure, particularly in the range of 0.13 Pa to 40,000 Pa (10⁻⁶). -3 Vapor pressures ranging from 1.3 Pa to 13,000 Pa (0.01 to 100 mmHg) and more particularly from 1.3 Pa to 1300 Pa (0.01 to 10 mmHg).

[0042] "Non-volatile oil" should be understood to mean an oil that remains on the skin or keratin fibers at room temperature and atmospheric pressure for at least several hours and, in particular, has a vapor pressure of less than 2.66 Pa, preferably less than 0.13 Pa. For example, based on vapor pressure (standard OECD 104), vapor pressure can be measured by static methods or via the effusion method performed by isothermal thermogravimetric analysis.

[0043] "Non-volatile alkanes" should be understood to mean alkanes that remain on the skin for at least several hours at room temperature and atmospheric pressure and, in particular, have a vapor pressure of less than 2.66 Pa, preferably less than 0.13 Pa. For example, based on vapor pressure (standard OECD 104), vapor pressure can be measured by static methods or via the effusion method performed by isothermal thermogravimetric analysis.

[0243] Among the water-soluble solvents that can be used in the compositions according to the invention, particularly mentioned are lower monohydric alcohols (such as ethanol and isopropanol) having 2 to 6 carbon atoms, diols (such as ethylene glycol, propylene glycol, glycerol, 1,3-butanediol, pentanediol, 1,3-propanediol and dipropylene glycol), C3 and C4 ketones, and C2-C4 aldehydes.

[0245] The water suitable for use in this invention can also be demineralized water.

[0246] The compositions of the present invention may contain water in an amount varying from 20% to 50% by weight and even more preferably from 30% to 45% by weight relative to the total weight of the composition.

[0247] Hydrophobic silica aerogel

[0248] The compositions of the present invention contain at least hydrophobic silica aerogel particles.

[0249] Silica aerogel is a porous material obtained by replacing the liquid component of silica gel with air (through drying).

[0250] They are typically synthesized in a liquid medium via a sol-gel process and then dried, usually by extraction with a supercritical fluid, most commonly supercritical CO2. This type of drying allows for the avoidance of pore and material shrinkage. The sol-gel process and various drying operations are described in detail in Brinker CJ and Scherer GW, *Sol-Gel Science*, New York, Academic Press, 1990.

[0251] The hydrophobic silica aerogel particles used in this invention preferably have a particle size in the range of 500 to 1500 μm. 2 / g, preferably 600 to 1200 m 2 / g and even better at 600 to 800 m 2 The specific surface area (SM) per unit mass / g, and the size expressed as the volume average diameter (D[0.5]) ranging from 1 to 1500 µm, more preferably 1 to 1000 µm, more preferably 1 to 100 µm, particularly 1 to 30 µm, more preferably 5 to 25 µm, more preferably 5 to 20 µm and even more preferably 5 to 15 µm.

[0252] The specific surface area per unit mass can be determined by a nitrogen adsorption method known as the BET (Bruno-Emmett-Teller) method, described in The Journal of the American Chemical Society, Vol. 60, p. 309, February 1938, and corresponding to International Standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles under consideration.

[0253] The size of silica aerogel particles can be measured by static light scattering using a commercial MasterSizer 2000® particle size analyzer from Malvern Corporation. The data is processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows for the determination of the “effective” particle size in the case of non-spherical particles. This theory is specifically described in the following publication: Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

[0254] According to an advantageous embodiment, the hydrophobic silica aerogel particles used in this invention have a particle size in the range of 600 to 800 μm. 2 Specific surface area per unit mass (SM) / g.

[0255] The silica aerogel particles used in this invention can advantageously have a concentration in the range of 0.02 to 0.10 g / cm³. 3 Preferably, the concentration is 0.03 to 0.08 g / cm³. 3 In particular, the range is 0.05 to 0.08 g / cm³. 3 The tap density r.

[0256] In the context of this invention, this density can be evaluated according to the following scheme (referred to as the tap density scheme):

[0257] Pour 40 g of powder into a graduated cylinder; then place the graduated cylinder on a Stav 2003® machine from the Stampf Volumeter; then perform a series of 2500 tapping motions on the graduated cylinder (repeat this operation until the volume difference between two consecutive tests is less than 2%); then measure the final volume Vf of the tapped powder directly on the graduated cylinder. The compacted density is determined by the ratio m / Vf, which in this case is 40 / Vf (Vf is expressed in cm³). 3 (This is represented by g).

[0258] According to a preferred embodiment, the hydrophobic silica aerogel particles used in this invention have a particle size ranging from 5 to 60 μm. 2 / cm 3 Preferably 10 to 50 m 2 / cm 3 And even better, 15 to 40 m 2 / cm 3 SV is the specific surface area per unit volume.

[0259] Specific surface area per unit volume is given by the following relationship: SV = SM xr, where r is the surface area in g / cm³. 3 The density is expressed as the actual density, and SM is expressed in m. 2 / g represents the specific surface area per unit mass, as defined above.

[0260] Preferably, the hydrophobic silica aerogel particles used according to the invention have an oil absorption capacity measured at the wet point in the range of 5 to 18 ml / g, preferably 6 to 15 ml / g, and even more preferably 8 to 12 ml / g.

[0261] The absorbency, measured at the wet point and expressed as Wp, corresponds to the amount of oil required to be added to 100 g of granules to obtain a uniform paste.

[0262] It is measured according to the wet point method or the method for determining the oil absorption rate of powder as described in standard NF T 30-022. It corresponds to the amount of oil adsorbed onto the usable surface of the powder and / or the amount of oil absorbed by the powder, as determined by measuring the wet point:

[0263] A certain amount of powder, m = 2 g, is placed on a glass plate, and then oil (isonononyl isononanoate) is added drop by drop. After adding 4 to 5 drops of oil to the powder, mix with a spatula and continue adding oil until an aggregate of oil and powder forms. From this point, add oil at a rate of one drop at a time and then grind the mixture with a spatula. Stop adding oil when a firm, smooth paste is obtained. This paste must be able to spread on a glass plate without breaking or forming clumps. The volume of oil used, Vs (in ml), is then recorded. The oil absorption rate corresponds to the ratio Vs / m.

[0264] The aerogel used in this invention is a hydrophobic silica aerogel, preferably a silylated silica aerogel (INCI name: silylated silica).

[0265] The term "hydrophobic silica" refers to any silica whose surface is treated with a silylating agent, such as a halogenated silane like alkylchlorosilane or silazane, so as to functionalize the OH group with a silyl Si-Rn, such as trimethylsilyl.

[0266] For the preparation of hydrophobic silica aerogel particles with surface modification via silylation, please refer to US 7 470 725.

[0267] Hydrophobic silica aerogel particles with trimethylsilyl surface modification will be preferred, preferably having the INCI name silylated silica.

[0268] Examples of hydrophobic silica aerogels that can be used in this invention include aerogels sold by Dow Corning under the names VM-2260® or VM-2270® (INCI name: silylated silica), whose particles have an average size of about 1000 micrometers and a range of 600 to 800 μm. 2 Specific surface area per unit mass of / g.

[0270] The preferred material will be an aerogel sold by Dow Corning under the name VM-2270 (INCI name: silylated silica), whose particles have an average size ranging from 5 to 15 micrometers and a particle size ranging from 600 to 800 μm. 2 Specific surface area per unit mass of / g.

[0271] Silica aerogel particles, particularly silylated silica aerogel particles, may be present in the composition at a content ranging from 0.5% to 13% by weight relative to the total weight of the composition according to the invention, preferably from 1% to 5% by weight, and particularly from 1% to 3% by weight.

[0272] Silicone emulsifying surfactants with HLB ≤ 8.0

[0273] The compositions according to the invention comprise at least one silicone emulsifying surfactant having an HLB of less than or equal to 8.0.

[0274] For the purposes of this invention, "emulsified surfactant" should be understood to mean an amphiphilic surfactant compound, i.e., a compound containing two parts of different polarities. Typically, one part is lipophilic (soluble or dispersible in an oil phase) and the other part is hydrophilic (soluble or dispersible in water). Emulsified surfactants are characterized by their HLB (hydrophilic-lipophilic balance) value, which is the ratio of the hydrophilic to the lipophilic portion of the molecule. The term "HLB" is well known and described, for example, in "The HLB System. A Time-saving Guide to Emulsifier Selection" (published by ICI Americas Inc.; 1984). For emulsified surfactants, for the preparation of W / O emulsions, the HLB is less than or equal to 8.0. The HLB of the surfactants used according to this invention can be determined by the Griffin method or the Davies method.

[0275] For the purposes of this invention, "silicone emulsifying surfactant" should be understood to mean a polyorganosiloxane that contains at least one hydrophilic chain in its structure, particularly at least one polyoxyalkylene (i.e., polyoxyethylene and / or polyoxypropyl) chain or polyglycerol chain.

[0276] The silicone emulsifying surfactant with HLB ≤ 8.0 is preferably present in the composition in an amount ranging from 0.1% to 10% by weight, more preferably from 1% to 8% by weight, relative to the total weight of the composition.

[0277] Among silicone emulsifying surfactants with HLB ≤ 8, polydimethylsiloxane copolyols may be mentioned, such as the product sold by Shin-Etsu under the trademark X-22-6711D® with the INCI name polydimethylsiloxane (and) PEG / PPG-18 / 18 polydimethylsiloxane (HLB = 2); alkyl polydimethylsiloxane copolyols, such as cetyl polydimethylsiloxane copolyols, for example cetyl PEG / PPG-10 / 1 polydimethylsiloxane (HLB = 5), such as the product sold by Evonik under the name Abil EM 90R®; and mixtures of cetyl polydimethylsiloxane copolyols, polyglycerol isostearate (4 mol), and hexyl laurate, sold by Evonik under the name Abil WE O9® is sold with INCI names: polyglycerol-4 isostearate (and) cetyl PEG / PPG-10 / 1 polydimethylsiloxane (and) hexyl laurate.

[0278] According to a particular form, the compositions of the present invention comprise a mixture of at least one silicone emulsifying surfactant with HLB ≤ 8.0, which is a mixture of polydimethylsiloxane, PEG / PPG-18 / 18 polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane, and more particularly a mixture of polydimethylsiloxane, PEG / PPG-18 / 18 polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane and polyglycerol-4 isostearate.

[0279] According to a specific form of the invention, the silicone emulsifying surfactant with HLB ≤ 8.0 may be selected from emulsified silicone elastomers.

[0280] The term "silicone elastomer" should be understood to refer to a flexible, deformable organopolysiloxane with viscoelastic properties, particularly a consistency similar to that of a sponge or flexible sphere. Its elastic modulus allows the material to withstand deformation and exhibits limited stretching and shrinkage. The material is able to return to its original shape after stretching.

[0281] Emulsified silicone elastomers can be selected from polyoxyethylene-modified silicone elastomers and polyglycerol-modified silicone elastomers, and mixtures thereof.

[0282] Polyoxyalkylated silicone elastomer

[0283] Polyoxyalkylated silicone elastomers are cross-linked organopolysiloxanes, which can be obtained by cross-linking addition reactions of a diorganopolysiloxane containing at least one hydrogen bonded to silicon with a polyoxyalkylene containing at least two olefinically unsaturated groups.

[0284] Preferably, the polyoxyethylene-crosslinked organopolysiloxane is obtained by a crosslinking addition reaction of a diorganopolysiloxane (A1) containing at least two hydrogens each bonded to silicon with a polyoxyethylene (B1) containing at least two olefinically unsaturated groups, particularly in the presence of a platinum catalyst (C1), for example, as described in patents US 5 236 986 and US 5 412 004.

[0285] Specifically, organopolysiloxanes can be obtained by reacting dimethylvinylsiloxy-terminated polyoxyethylene (especially polyethylene oxide and / or polypropylene oxide) with trimethylsiloxy-terminated methylhydropolysiloxane in the presence of a platinum catalyst.

[0289] Advantageously, polyoxyalkylene-based silicone elastomers can be formed by reacting divinyl compounds, particularly polyoxyalkylenes containing at least two vinyl groups, with the Si-H bonds of polysiloxanes.

[0290] The polyoxyalkylene-modified silicone elastomer according to the present invention is preferably mixed with at least one hydrocarbon oil and / or at least one silicone oil to form a gel. In these gels, the polyoxyalkylene-modified elastomer may be in the form of non-spherical particles.

[0343] The term "mineral pigment" refers to any pigment that meets the definition in the chapter on inorganic pigments in Ullmann's Encyclopedia. Among the mineral pigments that can be used in this invention, zirconium oxide or cerium dioxide may be mentioned, as well as zinc oxide, iron oxide (black, yellow, or red) or chromium oxide, manganese violet, ultramarine, chromium hydrate and iron blue, titanium dioxide, and metal powders (e.g., aluminum and copper powders). The following mineral pigments may also be used: Ta₂O₅, Ti₃O₅, Ti₂O₃, TiO, ZrO₂ in the form of a mixture with TiO₂, ZrO₂, Nb₂O₅, CeO₂, or ZnS.

[0344] The pigments used in the context of this invention are generally larger than 100 nm and can be in the range of up to 10 µm, preferably 200 nm to 5 µm and more preferably 300 nm to 1 µm.

[0345] According to a particular form of the invention, the pigment has a size characterized by D

[50] , which is greater than 100 nm and may be in the range of up to 10 µm, preferably 200 nm to 5 µm and more preferably 300 nm to 1 µm.

[0346] These dimensions were measured using a commercial MasterSizer 3000® particle size analyzer from Malvern by static light scattering, which allows for the determination of particle size distributions across a wide range, from 0.01 µm to 1000 µm. The data were processed based on standard Mie scattering theory. This theory is best suited for size distributions ranging from submicron to multimicron; it allows for the determination of the “effective” particle size. This theory is specifically described in the following publication: Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

[0347] D

[50] represents the maximum size represented by 50% of the particle's volume.

[0348] In the context of this invention, mineral pigments are more particularly iron oxide, titanium dioxide, and mixtures thereof. For example, more particularly, one may mention, for instance, titanium dioxide and iron oxide coated with aluminum stearoyl glutamate, sold by Miyoshi Kasei Co., Ltd. under the index number NAI®.

[0349] Mother-of-pearl can also be mentioned as a mineral pigment that can be used in this invention.

[0350] The term “mother-of-pearl” should be understood to mean any form of colored particles (which may be iridescent or non-iridescent), especially those produced within the shell of a certain mollusc or synthetically produced, and which have a coloring effect through optical interference.

[0351] Mother-of-pearl can be selected from pearlescent pigments, such as mica coated with titanium oxide and covered with iron oxide, mica coated with titanium oxide and covered with bismuth oxychloride, mica coated with titanium oxide and covered with chromium oxide, mica coated with titanium oxide and covered with organic dyes, and pearlescent pigments based on bismuth oxychloride. These pearlescent agents can also be mica particles with at least two layers of metal oxide and / or organic colorant layer superimposed on their surface in sequence.

[0352] According to a specific embodiment, the pigments used in this invention are selected from mineral pigments.

[0353] Other examples of mother-of-pearl that may be mentioned include natural mica coated with titanium dioxide, iron oxide, natural pigments, or bismuth oxychloride.

[0354] Mother-of-pearl can be more specifically characterized by its yellow, pink, red, bronze, orange, brown, gold, and / or copper colors or hues.

[0355] Among the pigments that can be used according to the invention, those pigments that have optical effects beyond simple conventional coloring effects may also be mentioned, i.e., the uniform and stabilizing effects produced by conventional colorants (e.g., monochromatic pigments). For the purposes of this invention, the term "stabilizing" means the absence of color variability with viewing angle or in response to temperature changes.

[0356] For example, the material can be selected from particles with metallic hues, visually luminescent colorants, diffractive pigments, thermochromic agents, optical brighteners, and fibers, especially interference fibers. Needless to say, these different materials can be combined to provide two effects simultaneously, or even novel effects according to the invention.

[0357] According to one particular embodiment, the composition according to the invention comprises at least one uncoated pigment.

[0358] According to another specific embodiment, the composition according to the invention comprises at least one pigment coated with at least one lipophilic or hydrophobic compound.

[0359] This type of pigment is particularly advantageous. When these pigments are treated with hydrophobic compounds, they exhibit a major affinity for the oil phase, which can then transport them.

[0360] The coating may also contain at least one additional non-lipophilic compound.

[0361] For the purposes of this invention, the term "coating" of a pigment according to the invention generally refers to the application of a surface treatment agent, which absorbs, adsorbs, or grafts onto the pigment, in whole or in part.

[0362] Surface-treated pigments can be prepared using surface treatment techniques known to those skilled in the art based on chemical, electrical, mechanochemical, or mechanical properties. Commercial products can also be used.

[0363] Surface agents can be absorbed, adsorbed, or grafted onto pigments through solvent evaporation, chemical reactions, and the formation of covalent bonds.

[0364] According to one variant, the surface treatment involves coating with pigments.

[0365] The coating may comprise 0.1% to 20% by weight of the total weight of the coated pigment, and particularly 0.5% to 5% by weight.

[0366] The coating can be produced, for example, by adsorbing a liquid surface agent onto the surface of solid particles by simply mixing the particles with the surface agent under stirring, or optionally under heating, before incorporating the particles into other ingredients of a cosmetic or care composition.

[0367] The coating can be produced, for example, by a chemical reaction between a surfactant and the surface of solid pigment particles, forming covalent bonds between the surfactant and the particles. This method is particularly described in patent US 4,578,266.

[0368] Chemical surface treatment may include diluting a surface agent in a volatile solvent, dispersing a pigment in the mixture, and then slowly evaporating the volatile solvent, causing the surface agent to deposit on the surface of the pigment.

[0369] When the pigment contains lipophilic or hydrophobic coatings, the coatings are preferably present in the fatty phase of the composition according to the invention.

[0370] According to a specific embodiment of the present invention, pigments can be coated with at least one compound selected from the following: silicone surface agents; fluorine surface agents; fluorosilicone surface agents; metal soaps; N-acyl amino acids or their salts; lecithin and its derivatives; isopropyl triisostearyl titanate; sebacic isostearyl sebacate; natural plant or animal waxes; polar synthetic waxes; fatty esters; phospholipids; and mixtures thereof.

[0371] According to a particular embodiment of the present invention, pigments can be coated with hydrophilic compounds.

[0372] According to one particular embodiment, the colorant is an organic pigment that is synthetic, natural, or has a natural source.

[0373] The term "organic pigment" refers to any pigment that meets the definition in the chapter on organic pigments in Ullmann's Encyclopedia. Organic pigments can be selected in particular from nitroso, nitro, azo, xanthracene, quinoline, anthraquinone, phthalocyanine, metal complex types, isoindolineone, isoindoline, quinacridone, violetone, perylene, diketopyrrolopyrrole, indigofera sulfide, dioxazine, triphenylmethane, or quinoline phthalone compounds.

[0374] Organic pigments may be selected from, for example, the following: carmine, carbon black, aniline black, melanin, azo yellow, quinacridone, phthalocyanine blue, sorghum red, blue pigments with color indices CI 42090, 69800, 69825, 73000, 74100 and 74160, yellow pigments with color indices CI 11680, 11710, 15985, 19140, 20040, 21100, 21108, 47000 and 47005, green pigments with color indices CI 61565, 61570 and 74260, orange pigments with color indices CI 11725, 15510, 45370 and 71105, and others with color indices CI 42090, 69800, 69825, 73000, 74100 and 74160. Red pigments 12085, 12120, 12370, 12420, 12490, 14700, 15525, 15580, 15620, 15630, 15800, 15850, 15865, 15880, 17200, 26100, 45380, 45410, 58000, 73360, 73915 and 75470 are included in the color index, as well as pigments obtained by oxidative polymerization of indole or phenol derivatives as described in patent FR 2 679 771.

[0375] Pigments can also be in the form of composite pigments, as described in patent EP 1 184 426. These composite pigments can in particular consist of particles comprising a mineral core at least partially covered with an organic pigment and at least one binder for fixing the organic pigment to the core.

[0376] Pigments can also be lakes. The term "lake" refers to an insoluble dye adsorbed onto insoluble particles, thereby making the resulting component insoluble during use.

[0377] The inorganic substrates on which the dye is adsorbed are, for example, alumina, silicon dioxide, sodium calcium borosilicate, or aluminum calcium borosilicate.

[0378] Among organic dyes, cochineal red can be mentioned. Products known by the following names may also be mentioned: D&C Red 21 (CI 45 380), D&C Orange 5 (CI 45 370), D&C Red 27 (CI 45 410), D&C Orange 10 (CI 45 425), D&C Red 3 (CI 45 430), D&C Red 4 (CI 15 510), D&C Red 33 (CI 17 200), D&C Yellow 5 (CI 19 140), D&C Yellow 6 (CI 15 985), D&C Green (CI 61 570), D&C Yellow 10 (CI 77 002), D&C Green 3 (CI 42 053), and D&C Blue 1 (CI 42 090).

[0435] Such compositions are prepared specifically based on the general knowledge of those skilled in the art.

[0436] Packaging and applicator

[0437] The composition according to the invention can be packaged in a container that defines at least one compartment for containing the composition, the container being closed by a sealing member.

[0438] The container can take any suitable form. It can specifically take the form of a bottle, tube, can, or box.

[0439] Closure components can take the form of removable plugs, caps, or hoods, particularly those comprising a body fixed to the container and a cap hinged to the body. They can also take the form of elements that ensure selective closure of the container, particularly pumps, valves, or shutters.

[0440] The container can be combined with an applicator, which is particularly in the form of a fine brush, as described, for example, in patent FR 2 722 380. The applicator can be in the form of a block of foam or elastomer. The applicator can be free (sponge) or securely fastened to a rod carried by a closure member, as described, for example, in patent US 5 492 426. The applicator can be integrated with the container, as described, for example, in patent FR 2 761 959.

[0441] Products can be contained directly or indirectly in containers.

[0442] The closure member can be connected to the container by screws. Alternatively, the connection between the closure member and the container can be made by means other than screws, particularly via a bayonet mechanism, by click-fastening, or by clamping. The term "click-fastening" should be understood in particular to mean any system involving the crossing of a bead or cord of material by elastic deformation of a portion, particularly the closure member, and subsequently returning to the elastically unconstrained position of said portion after the crossing.

[0444] Containers can have rigid or deformable walls, especially in the form of tubes or tubular bottles.

[0445] Containers may include means designed to cause or facilitate the dispensing of the composition. For example, a container may have deformable walls to allow the composition to exit in response to excessive pressure inside the container caused by elastic (or inelastic) compression of the container walls.

[0446] The container may be equipped with a wiper located near the opening of the container. This wiper enables the scraping of the applicator and, optionally, a rod that may be integrally attached to the applicator. Such a wiper is described, for example, in patent FR 2 792618.

[0447] Throughout the specification (including the claims), the term "comprising one" shall be understood to be synonymous with "comprising at least one" unless otherwise stated.

[0448] The phrases “between… and…” and “ranging from… to…” should be understood to include the limit values, unless otherwise stated.

[0449] The invention is illustrated in more detail by way of the examples presented below. Unless otherwise indicated, the indicated quantities are expressed as a weight percentage.

[0450] Examples 1 to 6

[0451] Comparative Examples 1 to 6 were prepared, with Example 1 being based on the present invention and Examples 2 to 6 being outside the present invention.

[0452] [Table 1]

[0453]

[0454] ( Outside of this invention

[0455] Preparation of the composition

[0456] Weigh out the components of phase A1 and stir the mixture at 85°C to obtain a homogeneous phase, and then cool it to 65°C.

[0457] Next, weigh out the components of A2 and add them to A1, and cool the combined mixture to 30°C. Then add the components of A3.

[0458] The pre-prepared aqueous phase B was emulsified in phase A by stirring at 2500 rpm for 20 minutes.

[0459] To prepare C, the pigment was milled in an air jet mill with 11.1% of its weight of synthetic fluorophlogopite. C was then introduced into emulsion A+B by stirring at 1500 rpm for 10 minutes.

[0460] Compared to Example 1 of the present invention, Example 6, which has a non-silicone emulsifying surfactant, exhibits phase separation at the surface, which appears as early as one month at room temperature and is exacerbated when the emulsion is stored at higher temperatures (e.g., 37°C).

[0461] A group of 14 people tested the foundation on their faces, with each sample receiving 0.075 ml.

[0462] Rate the following cosmetic standards on a scale of 0 to 15. The higher the score, the greater the cosmetic effect.

[0463] The results obtained are indicated in the table below.

[0464] [Table 2]

[0465]

[0466] Example 1 of the present invention demonstrates a good compromise among all tested cosmetic standards, unlike:

[0467] -Example 2, which is not related to the present invention and does not contain volatile alkanes (isododecane), was judged to have taken too long to dry and left a relatively soft, oily film on the skin after drying;

[0468] -Example 3, which does not contain non-cyclic volatile silicone oil (polydimethylsiloxane 2 cSt) outside of this invention, produced a film that was not very soft and not very slippery and did not leave a powdery, dry feeling.

[0469] -Example 4, which does not contain C15-19 alkanes and is not in this invention, produced a film that was not very soft and not very slippery, a less even makeup result, and did not leave a powdery or dry feeling.

[0470] Example 5, which contains silylated silica hydrophobic silica aerogel outside of this invention, was judged to take too long to dry and gave a possible powdery, dry feel and an uneven makeup result.
