Description

Title of the invention: Cosmetic water-in-oil emulsion comprising a specific water-soluble UV filter, a base, a volatile oil, a hydrophobic film-forming polymer, a linear polyoxyalkylated polydimethylmethyl siloxane, and vitamin B3. Technical field

[0001] The present invention relates to the field of skincare and / or makeup of keratinous materials, and aims to provide compositions more particularly dedicated to skincare and / or makeup.

[0002] The skin is not a smooth, uniformly colored surface and has raised areas and micro-reliefs such as pores, fine lines, wrinkles, blemishes, scars, and dry patches, which form a somewhat bumpy surface. Quite often, this surface, with its irregularities, forms a pleasing whole, but the irregularities are such that sometimes the surface is considered unsightly.

[0003] Cosmetic makeup and / or skincare compositions are commonly used to camouflage, smooth, and / or even out skin surface imperfections such as pores, wrinkles, fine lines, and / or scars. In this regard, numerous formulations, solid or fluid, anhydrous or non-anhydrous, have been developed to date.

[0004] Applying a makeup composition such as foundation is the most effective approach to beautifying uneven skin by concealing blemishes and discoloration, reducing the visibility of surface imperfections like pores and wrinkles, and masking blemishes and acne scars; in this respect, coverage is one of the main properties sought. These compositions generally use high concentrations of pigments based on metal oxides such as iron oxides and titanium dioxide, combined with particles called fillers that have a soft-focus effect. However, these compositions tend to accumulate in raised areas such as pores and wrinkles, leading to an uneven deposit on the skin, accentuating imperfections, and giving a matte finish perceived as unnatural.

[0005] There therefore remains a need to find new cosmetic compositions that are stable during storage, particularly with regard to temperature variations, and that effectively smooth and conceal skin imperfections thanks to good coverage performance, lasting throughout the day (wear), and that substantially reduce even to eliminate the marking effects of reliefs and mask effect on keratinous materials such as skin, to obtain good homogenization of the complexion and preferably a more natural less matte appearance as well as satisfactory cosmetic properties for the comfort of the consumer.

[0006] During its research, the applicant surprisingly discovered that this objective could be achieved with a composition in the form of a water-in-oil emulsion comprising: a) at least one continuous oily phase comprising at least one volatile oil selected from volatile hydrocarbon oils, volatile silicone oils and mixtures thereof, and b) at least one aqueous phase dispersed in said oily phase, comprising at least one water-soluble organic UV filter comprising at least one benzylidene camphosulfonic acid group and / or at least one water-soluble organic UV filter comprising at least one benzoxazole sulfonic acid group, and (c) at least one organic or inorganic base capable of partially or totally neutralizing said or water-soluble organic UV filters; and

[0007] d) at least one hydrophobic film-forming polymer, and (e) at least one emulsifying surfactant selected from linear polyoxyalkylated polydimethylmethylsiloxanes with an HLB < 8.0, and f) at least one vitamin B3; said composition not containing non-volatile ester oil.

[0008] This discovery is the basis of the invention.

[0009] The present invention relates to a composition in the form of a water-in-oil emulsion, in particular comprising a physiologically acceptable medium, in particular for coating keratinous materials, more particularly for makeup and / or care of keratinous materials, comprising: a) at least one continuous oily phase comprising at least one volatile oil selected from volatile hydrocarbon oils, volatile silicone oils and mixtures thereof, and b) at least one aqueous phase dispersed in said oily phase, comprising at least one water-soluble organic UV filter comprising at least one benzylidene camphosulfonic acid group and / or at least one water-soluble organic UV filter comprising at least one benzoxazole sulfonic acid group, and (c) at least one organic or inorganic base capable of partially or totally neutralizing said or water-soluble organic UV filters; and

[0010] d) at least one hydrophobic film-forming polymer, and (e) at least one emulsifying surfactant selected from linear polyoxyalkylated polydimethylmethylsiloxanes with an HLB < 8.0, and f) at least one vitamin B3; said composition not containing non-volatile ester oil.

[0011] The invention also relates to a method of coating keratinous materials, more particularly makeup and / or care of keratinous materials, such as skin, characterized in that it comprises the application on the keratinous materials of an emulsion as defined above.

[0012] The invention relates more particularly to a makeup and / or skin care method, characterized in that it comprises the application to the skin of an emulsion as defined above. Definitions

[0013] In the context of the present invention, keratinous materials mean the skin and more particularly areas such as the face, cheeks, hands, body, legs and thighs, the eye contour, eyelids.

[0014] Physiologically acceptable means compatible with the skin and / or its appendages, which has a pleasant color, odor and feel and which does not generate unacceptable discomforts (tingling, pulling) likely to deter the consumer from using this composition.

[0015] For the purposes of the present invention, an emulsifying surfactant is understood to be an amphiphilic surfactant compound, that is, one having two parts of different polarities. Generally, one is lipophilic (soluble or dispersible in an oil phase), and the other is hydrophilic (soluble or dispersible in water). Emulsifying surfactants are characterized by their HLB (Hydrophilic-Lipophilic Balance) value, the HLB being the ratio between the hydrophilic and lipophilic parts in the molecule. The term HLB is well known to those skilled in the art and is described, for example, in *The HLB System: A Time-Saving Guide to Emulsifier Selection* (published by ICI Americas Inc., 1984). For emulsifying surfactants, the HLB generally ranges from 3 to 8 for the preparation of oil-in-water emulsions. The HLB of the surfactant(s) used according to the invention can be determined by the GRIFFIN method or the DA VIES method.

[0016] By water-in-oil emulsion, we mean a composition comprising an oily phase and an aqueous phase that are not miscible; the aqueous phase being dispersed in the form of droplets in the oily phase (called continuous) so as to obtain a macroscopically homogeneous composition.

[0017] By oil, we mean a fatty organic substance that is liquid at room temperature (25°C) and atmospheric pressure (760mm of Hg or 105 Pa).

[0018] By non-volatile oil, we mean an oil that remains on the keratinous material at ambient temperature (25°C) and atmospheric pressure (760 mm Hg) at least several hours and having in particular a vapor pressure of less than 103 mm of Hg (0.13 Pa).

[0019] By non-volatile ester oil, we mean any non-volatile oil consisting of a single ester compound or a mixture of ester compounds. Said ester oil or mixture of ester oils is in particular made up of one or more mono, di-, triester(s) of a carboxylic acid having from 12 to 30 carbon atoms and a mono-alcohol or a polyol such as a glycol, in particular an alkylene glycol for example mixtures of esters with INCI names: Propylene Glycol Dicaprylate / Dicaprate and Butylene Glycol Dicaprylate / Dicaprate.

[0020] By composition not containing non-volatile ester oil, we mean any composition comprising less than 2.0% by weight of non-volatile ester oil, or even less than 1.0% by weight, or even less than 0.5% by weight relative to the total weight of the composition or even free of non-volatile ester oil.

[0027] For the purposes of this invention, volatile oil means any oil capable of evaporating upon contact with the skin in less than one hour at room temperature (25°C) and atmospheric pressure (760 mm Hg). Volatile oil is a volatile cosmetic compound, liquid at room temperature, having in particular a non-zero vapor pressure at room temperature and atmospheric pressure, in particular having a vapor pressure ranging from 0.13 Pa to 40,000 Pa (103 to 300 mm Hg), in particular ranging from 1.3 Pa to 13,000 Pa (0.01 to 100 mm Hg), and more particularly ranging from 1.3 Pa to 1,300 Pa (0.01 to 10 mm Hg).

[0066] For the purposes of the present invention, a hydrophobic film-forming polymer is defined as a film-forming polymer that has no affinity for water and, as such, is not suitable for formulation in the solute state in an aqueous medium. In particular, a hydrophobic polymer is defined as a polymer having a solubility in water at 25°C of less than 1% by weight.

[0067] By film-forming polymer, we mean a polymer capable of forming, on its own or in the presence of an auxiliary film-forming agent, a macroscopically continuous film on a support, in particular on keratinous materials, and preferably a cohesive film, and even better a film whose cohesion and mechanical properties are such that said film can be isolated and handled in isolation, for example when said film is made by pouring onto a non-stick surface such as a Teflon or silicone surface.

[0068] In particular, the hydrophobic film-forming polymer is a polymer selected from the group comprising film-forming polymers soluble in an organic solvent medium, in particular liposoluble polymers; this means that the polymer is soluble or miscible in the organic medium and will form a single homogeneous phase when incorporated into the medium.

I. Silicone Resins#

[0071] More generally, the term resin refers to a compound with a three-dimensional structure. Silicone resins are also called silicone resins or siloxane resins. Thus, for the purposes of the present invention, a polydimethylsiloxane is not a silicone resin.

[0072] The nomenclature of silicone resins (also called siloxane resins or silicone resins) is known as MDTQ, the resin being described according to the different siloxane monomeric units it comprises, each of the letters MDTQ characterizing a type of unit.

[0073] The letter M represents the Monofunctional unit of formula RiR2R3SiOi / 2, the silicon atom being bonded to a single oxygen atom in the polymer comprising this unit.

[0074] The letter D signifies a functional Di unit RiR2SiO2 / 2 in which the silicon atom is bonded to two oxygen atoms.

[0075] The letter T represents a Trifunctional unit of formula RiSiO3 / 2.

[0076] Such resins are described, for example, in the Encyclopedia of Polymer Science and Engineering, vol. 15, John and Wiley and Sons, New York, (1989), p. 265-270, and US 2,676,182, US 3,627,851, US 3,772,247, US 5,248,739 or even US 5,082,706, US 5,319,040, US 5,302, 685 and US 4,935,484.

[0077] In the motifs M, D, T defined above, R, namely Riet R2, represents a hydrocarbon radical (in particular alkyl) having from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or even a hydroxyl group.

[0078] Finally, the letter Q signifies a tetrafunctional SiO4 / 2 unit in which the silicon atom is bonded to four oxygen atoms which are themselves bonded to the rest of the polymer.

[0079] Various silicone resins of different properties can be obtained from these different units, the properties of these polymers varying according to the type of monomers (or units), the nature and number of the radical R, the length of the polymer chain, the degree of branching and the size of the dangling chains.

[0080] As examples of silicone resins that can be used in the compositions according to the invention, silicone resins of type MQ, type T or type MQT can be used.

[0081] As an example of MQ type silicone resins, alkylsiloxysilicates of formula [(Ri)3SiOi / 2] x(SiO4 / 2)y (MQ units) may be cited, in which x and y are integers from 50 to 80, and such that the Ri group represents a radical as defined above, and preferably is an alkyl group having from 1 to 8 carbon atoms or a hydroxyl group, preferably a methyl group.

[0083] Phenylalkylsiloxysilicate resins, such as phenylpropyldimethylsiloxysilicate (Silshine 151® marketed by General Electric), are also examples of silicone resins comprising MQ siloxysilicate motifs. The preparation of such resins is described, in particular, in US patent 5,817,302. a. Resins T #

[0084] As an example of T-type silicone resins, we can cite polysilsesquioxanes of formula (RSiO3 / 2)x (T units) in which x is greater than 100 and such that the R group is an alkyl group having from 1 to 10 carbon atoms, said polysilsesquioxanes being able to further comprise Si-OH terminal groups.

[0085] Preferably, polymethylsilsesquioxane resins can be used in which R represents a methyl group, such as those marketed: - by Wacker under the reference Resin MK®, such as Belsil PMS MK®: a polymer comprising repeating CH3SiO3 / 2 units (T units), which may also comprise up to 1% by weight of (CH3)2SiO2 / 2 units (D units) and having an average molecular weight of approximately 10,000 g / mol, or - by the company SHIN-ETSU under the references KR-220L® which are composed of T units of formula CH3SiO3 / 2 and have Si-OH terminal groups (silanol), under the reference KR-242A® which include 98% T units and 2% dimethyl D units and have Si-OH terminal groups or under the reference KR-251® which include 88% T units and 12% dimethyl D units and have Si-OH terminal groups. a. MQT Resins #

[0086] As a resin comprising MQT motifs, those cited in US document 5,110,890 are known in particular.

[0087] A preferred form of MQT-type resins is MQT-propyl resin (also called MQTPr). Such resins usable in the compositions according to the invention include, in particular, those described and prepared in application WO 2005 / 075542.

[0088] The MQ-T-propyl resin preferably comprises the following units: (i) (Rl3SiO1 / 2)a ;

[0089] (ii) (R22SiO2 / 2)b;

[0090] (iii) (R3SiO3 / 2)c ; and

[0096] Preferably, the siloxane resin comprises the following units:

[0097] (i) ((Rl)3SiO1 / 2)a ;

[0098] (iii) (R3SiO3 / 2)c ; and

[0099] (iv) (SiO4 / 2)d.

[0100] with: - RI and R3 independently represent an alkyl group having from 1 to 8 carbon atoms, RI preferably being a methyl group and R3 preferably being a propyl group, - a being between 0.05 and 0.5, preferably between 0.15 and 0.4, - c being greater than zero, preferably between 0.15 and 0.4, - d being between 0.05 and 0.6, preferably between 0.2 and 0.6, or even between 0.2 and 0.55, -a + b + c + d = leta, b, cetd being mole fractions, provided that more than 40% by mole of the R3 groups of the siloxane resin are propyl groups.

[0101] The siloxane resins usable according to the invention can be obtained by a process comprising the reaction of:

[0102] A) an MQ resin comprising at least 80 mole percent of ((Rl)3SiO1 / 2)a and (SiO4 / 2)d units; with

[0111] where the mass ratio A / B is between 95:5 and 15:85, preferably the mass ratio A / B is 30:70.

[0112] Advantageously, the mass ratio A / B is between 95:5 and 15:85. Preferably, the A / B ratio is less than or equal to 70:30. These preferred ratios have been shown to allow comfortable deposition due to the absence of percolation of rigid MQ resin particles in the deposit.

[0113] Thus, preferably, the silicone resin is chosen from MQ type resins, in particular chosen from (i) alkylsiloxysilicates, which may be trimethylsiloxysilicates, of formula [(Rl)3SiOi / 2]x(SiO4 / 2)y, in which x and y are integers from 50 to 80, and such that the RI group represents a hydrocarbon radical having from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or a hydroxyl group, and preferably is an alkyl group having from 1 to 8 carbon atoms, preferably a methyl group, and (ii) phenylalkylsiloxysilicate resins, such as phenylpropyldimethylsiloxysilicate resin.

[0230] According to a particular embodiment of the invention, the compositions according to the invention comprise at least one pigment coated by at least one lipophilic or hydrophobic compound and in particular as detailed below.

[0231] This type of pigment is particularly advantageous because it can be used in large quantities in conjunction with a large quantity of water. Moreover, when treated with a hydrophobic compound, it exhibits a predominant affinity for the oily gel phase, which can then carry it.

[0232] Of course, the compositions according to the invention may also contain uncoated pigments.

[0233] The coating may also include at least one additional non-lipophilic compound.

[0234] For the purposes of the invention, the coating of a pigment according to the invention generally refers to the total or partial surface treatment of the pigment by a surfactant, absorbed, adsorbed or grafted onto said pigment.

[0235] Surface-treated pigments can be prepared using surface treatment techniques of a chemical, electronic, mechano-chemical or mechanical nature well known to those skilled in the art. Commercial products can also be used.

[0236] The surfactant can be absorbed, adsorbed or grafted onto pigments by solvent evaporation, chemical reaction and creation of a covalent bond.

[0237] According to one variant, the surface treatment consists of coating the pigments.

[0238] The coating may represent from 0.1% to 20% by weight, and in particular from 0.5% to 5% % by weight, of the total weight of the coated pigment.

[0239] The coating can be achieved, for example, by adsorption of a liquid surfactant onto the surface of the solid particles by simple mixing under agitation of the particles and said surfactant, possibly heated, prior to the incorporation of the particles into the other ingredients of the makeup or skincare composition.

[0240] The coating can be achieved, for example, by a chemical reaction of a surfactant with the surface of the solid pigment particles and the creation of a covalent bond between the surfactant and the particles. This method is described in particular in US patent 4,578,266.

[0241] Chemical surface treatment may consist of diluting the surfactant in a volatile solvent, dispersing the pigments in this mixture, and then slowly evaporating the volatile solvent so that the surfactant is deposited on the surface of the pigments. Lipophilic or hydrophobic treatment agent

[0242] When the pigment includes a lipophilic or hydrophobic coating, the latter is preferably present in the oily phase of the composition according to the invention.

[0243] According to a particular embodiment of the invention, the pigments can be coated according to the invention by at least one compound selected from silicone surfactants; fluorinated surfactants; fluoro-siliconized surfactants; metallic soaps; N-acylated amino acids or their salts; lecithin and its derivatives; isopropyl triisostearyl titanate; isostearyl sebacate; natural vegetable or animal waxes; polar synthetic waxes; fatty esters; phospholipids; and mixtures thereof.

[0245] Silicone surfactants may be selected from organopolysiloxanes, silane derivatives, silicone-acrylate copolymers, silicone resins, and mixtures thereof.

[0246] By organopolysiloxane compound is meant a compound having a structure comprising an alternation of silicon atoms and oxygen atoms and comprising organic radicals linked to the silicon atoms. Non-elastomer organopolysiloxane

[0247] Examples of non-elastomeric organopolysiloxanes include polydimethylsiloxanes, polymethylhydrogenosiloxanes and polyalkoxydimethylsiloxanes.

[0249] A method for treating the surface of pigments with a polymethylhydrogenosiloxane consists of dispersing the pigments in an organic solvent, then adding the silicone compound. By heating the mixture, covalent bonds are formed between the silicone compound and the surface of the pigment.

[0250] According to a preferred embodiment, the silicone surfactant may be a non-elastomeric organopolysiloxane, in particular selected from polydimethylsiloxanes. Alkylsilanes and alkoxysilanes

In particular, such dimethicones may comprise, as repeating units, alkylene oxides in the form Ci-C2O, such as ethylenic or propylenic.

[0328] As an example, we can cite the pigment treated with PEG-12-Dimethicone, marketed by the company SENSIENT CORPORATION, under the name LCW AQ® Pigment.

[0329] The quantity of pigments coated by at least one hydrophilic compound and / or uncoated pigments is in particular conditioned by the purpose of the cosmetic composition in question and its adjustment is of course within the competence of the formulator of the composition. Non-emulsifying organopolysiloxane elastomer

[0330] According to a preferred embodiment of the invention, the composition further comprises at least one non-emulsifying organopolysiloxane elastomer.

[0331] The term non-emulsifying defines organopolysiloxane elastomers not containing a hydrophilic chain, and in particular not containing polyoxyalkylene motifs (in particular polyoxyethylene or polyoxypropylene), nor polyglyceryl motifs.

[0332] Thus, the organopolysiloxane elastomer can be obtained by addition-crosslinking reaction of a diorganopolysiloxane containing at least one hydrogen bonded to silicon and a diorganopolysiloxane having ethylenic unsaturated groups bonded to silicon, particularly in the presence of a platinum catalyst; or by condensation-crosslinking-dehydrogenation reaction between a hydroxyl-terminated diorganopolysiloxane and a diorganopolysiloxane containing at least one hydrogen bonded to silicon, particularly in the presence of an organotin; or by condensation-crosslinking reaction of a diorganopolysiloxane with hydroxyl-terminated hydroxyl and a hydrolyzable organopolysiloxane; or by thermal crosslinking of organopolysiloxane, particularly in the presence of organoperoxide catalyst; or by crosslinking of organopolysiloxane by high-energy radiation such as gamma rays, ultraviolet rays, electron beam.

[0333] Preferably, the organopolysiloxane elastomer is obtained by addition crosslinking reaction (A) of diorganopolysiloxane containing at least two hydrogens each linked to a silicon, and (B) of diorganopolysiloxane having at least two ethylenic unsaturation groups linked to silicon, in particular in the presence (C) of platinum catalyst.

[0334] In particular, the organopolysiloxane elastomer can be obtained by reaction of dimethylpolysiloxane with dimethylvinylsiloxy terminations and methylhydrogenopolysiloxane with trimethylsiloxy terminations, in the presence of platinum catalyst.

[0335] Compound (A) is the basic reagent for the formation of organopolysiloxane elastomer and crosslinking is carried out by addition reaction of compound (A) with compound (B) in the presence of catalyst (C).

[0336] Compound (A) is in particular an organopolysiloxane having at least two hydrogen atoms bonded to distinct silicon atoms in each molecule.

[0337] Compound (A) may have any molecular structure, including a linear chain structure or a branched chain structure or a cyclic structure.

[0338] The compound (A) may have a viscosity at 25°C ranging from 1 to 50000 centistokes, in particular to be well miscible with the compound (B).

[0339] The organic groups bonded to the silicon atoms of compound (A) may be alkyl groups such as methyl, ethyl, propyl, butyl, octyl; substituted alkyl groups such as 2-phenylethyl, 2-phenylpropyl, 3,3,3-trifluoropropyl; aryl groups such as phenyl, tolyl, xylyl; substituted aryl groups such as phenylethyl; and substituted monovalent hydrocarbon groups such as an epoxy group, a carboxylate ester group, or a mercapto group.

[0340] Compound (A) can thus be chosen from trimethylsiloxy-terminated methylhydrogenopolysiloxanes, trimethylsiloxane-methylhydrogenosiloxane-terminated dimethylsiloxane copolymers, and dimethylsiloxane-methylhydrogenosiloxane cyclic copolymers.

[0341] Compound (B) is advantageously a diorganopolysiloxane having at least two lower alkenyl groups (for example, at C2-C4); the lower alkenyl group may be selected from vinyl, allyl, and propenyl groups. These lower alkenyl groups may be located at any position in the organopolysiloxane molecule but are preferably located at the ends of the organopolysiloxane molecule. The organopolysiloxane (B) may have a branched-chain, linear-chain, cyclic, or network structure, but the linear-chain structure is preferred. The compound (B) may have a viscosity ranging from the liquid state to the gum state. Preferably, compound (B) has a viscosity of at least 100 centistokes at 25°C.

[0342] Besides the aforementioned alkenyl groups, the other organic groups bonded to the silicon atoms in compound (B) may be alkyl groups such as methyl, ethyl, propyl, butyl or octyl; substituted alkyl groups such as 2-phenylethyl, 2-phenylpropyl or 3,3,3-trifluoropropyl; aryl groups such as phenyl, tolyl or xylyl; substituted aryl groups such as phenylethyl; and substituted monovalent hydrocarbon groups such as an epoxy group, a carboxylate ester group, or a mercapto group.

[0343] Organopolysiloxanes (B) may be selected from methylvinylpolysiloxanes, methylvinylsiloxane-dimethylsiloxane copolymers, dimethylpolysiloxanes with dimethylvinylsiloxy terminations, dimethylsiloxane-methylphenylsiloxane copolymers with dimethylvinylsiloxy terminations, dimethylsiloxane-diphenylsiloxane-methylvinylsiloxane copolymers with dimethylvinylsiloxy terminations, dimethylsiloxane-methylvinylsiloxane copolymers with trimethylsiloxy terminations, dimethylsiloxane-methylphenylsiloxane-methylvinylsiloxane copolymers with trimethylsiloxy terminations, methyl(3,3,3-trifluoropropyl)polysiloxane with dimethylvinylsiloxy terminations, and copolymers dimethylsiloxane-methyl(3,3,3-trifluoropropyl)siloxane with dimethylvinylsiloxy endings.

[0344] In particular, the organopolysiloxane elastomer can be obtained by reaction of dimethylpolysiloxane with dimethylvinylsiloxy terminations and methylhydrogenopolysiloxane with trimethylsiloxy terminations, in the presence of platinum catalyst.

[0345] According to another embodiment, compound (B) may be an unsaturated hydrocarbon compound having at least two lower alkenyl groups (for example, at C2-C4); the lower alkenyl group may be selected from vinyl, allyl, and propenyl groups. These lower alkenyl groups may be located at any position in the molecule but are preferably located at the ends. Hexadiene, and in particular 1,5-hexadiene, is an example.

[0346] Advantageously, the sum of the number of ethylenic groups per molecule of compound (B) and the number of hydrogen atoms bonded to silicon atoms per molecule of compound (A) is at least 5.

[0347] It is advantageous that compound (A) be added in such an amount that the molecular ratio between the total amount of hydrogen atoms bonded to silicon atoms in compound (A) and the total amount of all ethylenic unsaturating groups in compound (B) is in the range of 1.5 / 1 to 20 / 1.

[0348] Compound (C) is the catalyst for the crosslinking reaction, and includes, in particular, chloroplatinic acid, chloroplatinic acid-olefin complexes, chloroplatinic acid-alkenylsiloxane complexes, chloroplatinic acid-diketone complexes, black platinum, and platinum on support.

[0349] The catalyst (C) is preferably added from 0.1 to 1000 parts by weight, better from 1 to 100 parts by weight, as clean platinum metal for 1000 parts by weight of the total amount of compounds (A) and (B).

[0373] According to a preferred form, the composition according to the invention comprises, in addition to the silica particles chosen by the hydrophobic silica aerogel particles, the silica particles different from the former, and mixtures thereof. i. Hydrophobic silica aerogels #

[0374] Hydrophobic silica aerogels are porous materials obtained by replacing (notably by drying) the liquid component of a silica gel with air. They are generally synthesized by the sol-gel process in a liquid medium and then dried, usually by extraction from a supercritical fluid, most commonly supercritical CO2. This type of drying prevents the contraction of the pores and the material. The sol-gel process and the various drying methods are described in detail in Brinker CL, and Scherer GW, Sol-Gel Science: New York: Academie Press, 1990.

[0375] The hydrophobic silica aerogels used according to the present invention are preferably silylated silica aerogels (INCI name Silica Silylate).

[0376] By hydrophobic silica is meant any silica whose surface is treated by silylation agents, for example by halogenated silanes such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups by silyl Si-Rn groups, for example trimethylsilyl groups.

[0377] Regarding the preparation of surface-modified hydrophobic silica aerogel particles by silylation, reference can be made to US document 7,470,725.

[0378] In particular, hydrophobic silica aerogel particles modified on the surface by trimethylsilyl groups (trimethylsiloxylated silica) will be used.

[0379] By hydrophobic aerogel particles, we mean any aerogel-type particle having a water absorption capacity at the WET POINT of less than 0.1ml / g, i.e., less than 10g of water per 100g of particle.

[0380] The absorption capacity measured at the Wet Point, and denoted WP, ​​corresponds to the quantity of a solvent (expressed in grams or milliliters) that must be added to 1 g of particles to obtain a homogeneous paste. It is measured according to the so-called Wet Point method or method for determining the solvent (water or oil) uptake of powder described in standard NF T 30-022. It corresponds to the quantity of solvent adsorbed onto the available surface of the powder and / or absorbed by the powder by Wet Point measurement, described below:

[0381] A glass plate (25 x 25 mm) is placed on a balance, and a quantity m of 1 g of powder is weighed onto the glass plate. A solvent (water or isononyl isononanoate, for example) is then added drop by drop. The solvent is gradually added to the powder, mixing the mixture regularly (every 3 to 4 drops) with a spatula. The addition of solvent is stopped when a homogeneous paste is obtained. This paste should spread easily on the glass plate without cracking or lump formation. The mass of solvent required to obtain the wet point is recorded. The average is calculated over 3 trials. Knowing the density of the solvent, the volume Vs (expressed in ml) of solvent used is deduced. The solvent intake corresponds to the ratio Vs / m.

[0382] Preferably, the hydrophobic silica aerogel particles according to the invention preferably have an oil absorption capacity measured at the WET POINT ranging from 5 to 18 ml / g, preferably from 6 to 15 ml / g and better from 8 to 12 ml / g.

[0383] The hydrophobic silica aerogel particles used in the present invention preferably have a specific surface area per unit mass (SM) of 200 to 1500 m2 / g, preferably 600 to 1200 m2 / g and better 600 to 800 m2 / g, and a size expressed as volume mean diameter (D [0.5]) less than 1500 pm and preferably 1 to 30 pm, preferably 5 to 25 pm, better 5 to 20 pm and even better 5 to 15 pm.

[0384] The specific surface area per unit mass can be determined by the nitrogen absorption method known as the BET (BRUNAUER-EMMET-TELLER) method, described in The Journal of the American Chemical Society, vol. 60, page 309, February 1938, and corresponding to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles considered.

[0385] The particle sizes of the aerogel according to the invention can be measured by static light scattering using a commercial particle size analyzer such as the Malvern Master Sizer 2000®. The data are processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows the determination of an effective particle diameter in the case of non-spherical particles. This theory is described in particular in Van de Hulst, H.C., *Light Scattering by Small Particles*, Chapters 9 and 10, Wiley, New York, 1957.

[0386] The hydrophobic silica aerogel particles used in the present invention may advantageously have a packed density ranging from 0.02g / cm3 to 0.10 g / cm3, preferably from 0.02g / cm3 to 0.08g / cm3.

[0387] Within the framework of the present invention, this density can be assessed according to the following protocol, known as the packed density protocol: Forty grams of powder are poured into a graduated cylinder; the cylinder is then placed on the STAMPF VOLUMETER STAV 2003® apparatus; the cylinder is then subjected to a series of 2500 compactions (this operation is repeated until the volume difference between two consecutive tests is less than 2%); the final volume Vf of compacted powder is then measured directly on the cylinder. The compacted density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm³ and m in g).

[0388] According to one embodiment, the hydrophobic aerogel particles used in the present invention have a specific surface area per unit volume Svallant of 5 to 60 m² / cm², preferably of 10 to 50 m² / cm² and better of 15 to 40 m² / cm².

[0389] The specific surface area per unit volume is given by the relation: Sv = SM.p where p is the packed density expressed in g / cm3 and SM is the specific surface area per unit mass expressed in m2 / g, as defined above.

[0390] According to a particular embodiment, the aerogel particles used are inorganic and more particularly hydrophobic silica aerogel particles having the properties stated above.

[0391] As examples of hydrophobic silica aerogels that can be used in the invention, one can cite, for example, the aerogel marketed under the name VM-2260 (INCI name Silica Silylate), by the company Dow Corning, whose particles have an average size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0392] We can also mention the aerogels marketed by the Cabot company under the references AEROGEL TLD 201®, AEROGEL OGD 201® and AEROGEL TLD 203®, ENOVA® AEROGEL MT 1100, ENOVA AEROGEL MT 1200®.

[0393] In particular, we will use T aerogel marketed under the name VM-2270® (INCI name Silica Silylate), by the company Dow Corning, whose particles have an average size ranging from 5-15 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0394] We will also use T aerogel marketed under the name Enova® Aerogel MT 1100® (INCI name Silica Silylate), by the company CABOT, whose particles have an average size ranging from 2-25 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0395] Hydrophobic aerogel particles represent 0.05 to 10% by weight, preferably 0.1 to 8% by weight, better 0.2 to 5% by weight, preferably still 0.3 to 3% by weight relative to the total weight of the composition Other silica particles

[0396] Other usable silicas can be natural and untreated. Examples include the silicas offered under the names SILLITIN N85®, SILLITIN N87®, SILLITIN N82®, SILLITIN V85® and SILLITIN V88® by the company HOFFMANN MINERAL.

[0397] They can be pyrogenated.

[0398] Fumed silicas can be obtained by high-temperature hydrolysis of a volatile silicon compound in an oxyhydrogen flame, producing finely divided silica. This process makes it possible, in particular, to obtain hydrophilic silicas that have a significant number of silanol groups on their surface. It is possible to chemically modify the surface of said silica by a chemical reaction that reduces the number of silanol groups. In particular, one can substitute silanol groups are combined with hydrophobic groups: this results in hydrophobic silica.

[0399] Hydrophobic groups can be: (a) trimethylsiloxyl groups, which are obtained in particular by treating fumed silica in the presence of hexamethyldisilazane. Silicas treated in this way are designated Silica Silylate according to the CTFA (6th edition, 1995). (b) dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are designated Silica Dimethyl Silylate according to the CTFA (6th edition, 1995).

[0400] Silica powders other than silica aerogels include, in particular: - porous silica microspheres sold under the name SILICA BEADS SB-700® by the company MYOSHI; SUNSPHERE® H51, SUNSPHERE® H33 by the company ASAHI GLASS; - amorphous silica microspheres coated with polydimethylsiloxane sold under the name SA SUNSPHERE® H 33®, SA SUNSPHERE® H53® by the company AGC SITECH; - precipitated silica microspheres for example coated with mineral wax such as polyethylene and notably sold under the name ACEMATT OK 412® by the company EVONIK DEGUSSA.

[0401] As silica powder, porous silica microspheres such as those sold under the name SILICA BEADS SB-700® by the company MYOSHI; SUNSPHERE® H51, SUNSPHERE® H33 by the company AGC SITECH will be used in particular.

[0406] The additional coloring materials suitable for the invention can be water-soluble but also fat-soluble.

[0427] a. Preparation of the aqueous phase: #

[0428] All the ingredients of phase B1 were weighed and the mixture was stirred in a Rayneri (deflocculator). The pH was adjusted with sodium hydroxide and the amount of lost water was added. a. Preparation of the oil phase: #

[0429] The non-volatile dimethicone from phase C was weighed, followed by the isododecane and surfactants from phase A1, which were mixed under a Moritz mixer (rotor / stator) for 5 minutes, adjusting the speed to create a vortex. The mixture was then placed in an ice water bath. The silicone elastomer from phase A3 was weighed and mixed for 15 minutes, adjusting the speed to maintain a vortex. The film-forming polymer from phase A3 and the fillers from phase A4 were then weighed. It is possible to pre-disperse DOW CORNING VM-2270® AEROGEL FINE PARTICLES - DOW CORNING in isododecane to facilitate application. The mixtures were then combined for 15 minutes, adjusting the speed to maintain a vortex. a. Emulsification#

[0430] The emulsion was carried out under Moritz conditions and always under an ice bath by introducing the aqueous phase into the oil phase. It was left for 20 minutes at a speed of 1300 rpm (gradually increasing / vortex).

[0431] Alcohol was then added under Rayneri and allowed to disperse for 5 min while maintaining the temperature below 40°C. Haze measurements

[0432] Examples 1 and 2 of the invention with niacinamide and counterexamples 1a and 1b were subjected to HAZE performance measurements after spreading into films, according to the following protocol: a. Spreading Protocol#

[0433] Each composition to be tested was spread using an automatic spreader into a 25 sq m thick film on a transparent polyester sheet. The resulting deposit was left for 1 hour at room temperature (25°C). a. Haze measurement protocol#

[0434] HAZE measurements were carried out using HAZE GARDE® equipment (HAZE GARD PLUS BRANT INDUSTRIE SARL - BYK_GARDNER).

[0435] The laser was switched on 1 hour before the measurements. After a calibration phase of The device placed the film, which had been dried for one hour, in the path of the laser. Haze measurements were automatically performed by the device.

[0436] Three spreads of each composition were prepared, and 10 HAZE measurements were taken per composition to determine a mean HAZE value and a standard deviation. The results are shown in the table below. Stability tests

[0437] Examples 1 and 1b were introduced at a dose of 20g into a glass pillbox. Each pillbox was placed for 10 days in a HERAEUS VOETSCH® type cycle incubator. Every 24 hours, each pillbox underwent the following four 6-hour temperature cycles: 6 hours at +20°C 6 hours of gradual temperature drop from 20°C to -20°C 6 hours at -20°C 6 hours of gradual temperature rise from -20°C to +20°C

[0438] After ten days, the appearance of each specimen was observed 1 and 1b i) macroscopically with the naked eye; and ii) microscopically with the LEICA DM2500® microscope at X10 magnification. The results obtained are shown in Tables 2 and 3 below.
