Description

The present application relates to a composition for topical application comprising at least one aqueous phase, at least one fatty phase, at least one superabsorbent polymer and hydrophobic silica airgel particles, and the use of said composition in the cosmetic and dermatological fields, in particular for the care, the treatment of keratin materials. In the field of cosmetics, and more particularly in the field of skincare, photoprotection or make-up, it is known from US patent application 2010033018 to introduce into galenics of the emulsion type oil-dan-water or eaudans oil superabsorbent water polymers because they give the textures interesting sensory effects such as freshness, or a reduction of stickiness. This type of galenic nonetheless has the defect of having a poorly homogeneous spread on the skin, and the presence of pulverulent material causes a linting phenomenon (particle formation) after application. There remains therefore a need to produce stable cosmetic compositions such as oil-in-water or water-in-oil emulsions containing a superabsorbent polymer, having a uniform application on the skin, and not linting after application. The Applicant has discovered that the cosmetic compositions comprising an aqueous phase, a superabsorbent polymer and hydrophobic silica airgel particles made it possible to produce sensually interesting textures, having a homogeneous spread on the skin and not fluffing after application. Thus, the subject of the present invention is a composition for topical application comprising at least one aqueous phase, at least one fatty phase, at least one superabsorbent polymer and hydrophobic silica airgel particles. Since the composition of the invention is intended for topical application to the skin or superficial body growths, it comprises a physiologically acceptable medium, ie a medium that is compatible with all keratin materials such as the skin, the nails, the mucous membranes and keratin fibers (such as hair, eyelashes). The composition according to the invention has the advantage of having a very soft texture, non-sticky and fresh to the application, so very pleasant to use, while having a consistent spread on the skin and not fluffing after application. The subject of the invention is also a process for the cosmetic treatment of keratinous substances consisting in applying to the keratin materials a composition as defined above.

The subject of the invention is also the use of said composition in the cosmetic or dermatological field, and in particular for the care, the protection and / or the make-up of the skin of the body or of the face, or for the care of the hair .

Superabsorbent Polymers The term "superabsorbent polymer" is intended to mean a polymer which is capable, in its dry state, of spontaneously absorbing at least 20 times its own weight of aqueous fluid, in particular water and especially distilled water. Such superabsorbent polymers are described in the book "Absorbent Polymer Technology, Studies in Polymer Science 8" by L. BRANNON-PAPPAS and R. HARLAND, Elsevier edition, 1990. These polymers have a great capacity for absorption and retention. water and aqueous fluids. After absorption of the aqueous liquid, the polymer particles so imbibed with aqueous fluid remain insoluble in the aqueous fluid and thus retain their individualized particulate state.

The superabsorbent polymer can have a water absorption capacity ranging from 20 to 2000 times its own weight (ie 20 g to 2000 g absorbed water per gram of absorbent polymer), preferably from 30 to 1500 times, and better from 50 to 1000 times. These water absorption characteristics are defined under normal conditions of temperature (25 ° C) and pressure (760 mmHg or 100000 Pa) and for distilled water.

The value of the water absorption capacity of a polymer can be determined by dispersing 0.5 g of polymer (s) in 150 g of a water solution, while waiting for 20 minutes, filtering the non-aqueous solution. absorbed on a 150 μm filter for 20 minutes and weighing the unabsorbed water.

Hydrophobic Silica Aerogels Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized by sol-gel process in a liquid medium and then usually dried by extraction of a supercritical fluid, the most commonly used being supercritical CO2. This type of drying avoids the contraction of the pores and the material. The sol-gel process and the various dryings are described in detail in Brinker CJ, and Scherer G.VV., Sol-Gel Science: New York: Academic Press, 1990. The hydrophobic silica airgel particles used herein The present invention has a surface area per unit mass (SM) of from 500 to 1500 m 2 / g, preferably from 600 to 1200 m 2 / g and more preferably from 600 to 800 m 2 / g, and a size expressed as a volume average diameter ( D [0.5]) ranging from 1 to 1500 μm, better still from 1 to 1000 μm, preferably from 1 to 100 μm, in particular from 1 to 30 μm, more preferably from 5 to 25 μm, better still from 5 to 20 μm. pm and even better better from 5 to 15 pm. According to one embodiment, the hydrophobic silica airgel particles used in the present invention have a size expressed in volume mean diameter (D [0.5]) ranging from 1 to 30 μm, preferably from 5 to 25 μm. better from 5 to 20 μm and even better from 5 to 15 μm. The specific surface area per unit mass can be determined by the nitrogen absorption method called the BET method (BRUNAUER - EMMET - TELLER) described in "The Journal of the American Chemical Society", vol. 60, page 309, February 1938 and corresponding to the international standard ISO 5794/1 (Appendix D). The BET surface area corresponds to the total specific surface area of the particles under consideration. The silica airgel particle sizes can be measured by static light scattering using a MasterSizer 2000 commercial particle size analyzer from Malvern. The data is processed on the basis of Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" diameter of particles. This theory is particularly described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wley, New York, 1957.

According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface per unit mass (SM) ranging from 600 to 800 m 2 / g and a size expressed in volume mean diameter (D [0.5]) ranging from 5 to 20 μm and even more preferably from 5 to 15 μm. The silica airgel particles used in the present invention may advantageously have a packed density (p ranging from 0.04 g / cm 3 to 0.10 g / cm 3, preferably from 0.05 g / cm 3 to 0.08 g / cm 3.

In the context of the present invention, this density can be assessed according to the following protocol, called the packed density: 40 g of powder are poured into a graduated test tube; then the specimen is placed on the STAV 2003 device from STAMPF VOLUMETER; the test piece is then subjected to a series of 2500 settlements (this operation is repeated until the difference in volume between two consecutive tests is less than 2%); then the final volume Vf of compacted powder is measured directly on the test piece. The packed density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm3 and m in g).

According to one embodiment, the hydrophobic silica airgel particles used in the present invention have a specific surface area per unit volume Sv ranging from 5 to 60 m 2 / cm 3, preferably from 10 to 50 m 2 / cm 3 and more preferably 15 to 50 m 2 / cm 3. at 40 m2 / cm3. The specific surface area per unit volume is given by the relation: Sv = SM xp. 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 more high. Preferably, the hydrophobic silica aerogel particles according to the invention have an oil absorption capacity measured with WET POINT ranging from 5 to 18 ml / g, preferably from 6 to 15 ml / g and better still from 8 to 18 ml / g. at 12 ml / g. The absorption capacity measured at Wet Point, and denoted by Wp, corresponds to the amount of oil that must be added to 100 g of particles in order to obtain a homogeneous paste. It is measured according to the so-called Wet Point method or method for determining the setting of powder oil described in standard NF T 30-022. It corresponds to the quantity of oil adsorbed on the available surface of the powder and / or absorbed by the powder by measuring the Wet Point, described below: A quantity m = 2 g of powder is placed on a glass plate and then the oil (isononyl isononanoate) is added dropwise. After addition of 4 to 5 drops of oil in the powder, mixing is carried out with a spatula and oil is added until the formation of oil and powder conglomerates. From this moment, the oil is added one drop at a time and then triturated with the spatula. The addition of oil is stopped when a firm and smooth paste is obtained. This paste should be spread on the glass plate without cracks or lumps. The volume Vs (expressed in ml) of oil used is then noted. The oil intake corresponds to the ratio Vs / m. The aerogels used according to the present invention are aerogels of hydrophobic silica, preferably of silylated silica (INCI name silica silylate).
