Definitions

• the present invention relates to a cosmetic composition, in particular a hair composition, containing silicate particles in a support of the oil-in-water emulsion type. It also relates to a cosmetic treatment process for the hair comprising the application of this composition as well as its use as a hair product.
• hair cosmetic compositions contain a film-forming polymer, which applied in the form of a solution, allows the formation, after evaporation of the solvent, of a film sheathing the hair. It is known that many of these film-forming polymers used in cosmetic compositions for hair have in common in particular the property of strengthening the maintenance of the hairstyle.
• the deposition of these fimogenic polymers can be carried out by means of lotions propelled or not by l 'through an aerosol device, foam, gels or emulsions.
• the support obtained with these film-forming polymers is generally not very durable over time and the feel imparted is not always very natural, so that there is a need for compositions providing the eratin fibers with a natural and lasting support while preserving or increasing the natural shine of the fibers.
• compositions intended for the photoprotection of the skin or of the hair containing, in a cosmetically acceptable support of the oil-in-water ultrafine emulsion type, in which globules which constitute the oily phase is between 100 nm and 1 ⁇ m, at least one silicate of alkali metals and / or alkaline earth metals, in the presence of nanoparticles photoprotective of metal oxides.
• these compositions have the disadvantage of sometimes making the hair heavy, charged and difficult to untangle and dull.
• the Applicant has discovered, surprisingly and unexpectedly, that by choosing an emulsion of the oil-in-water type, the size of the oil globules forming the fatty phase is within a defined range and the aqueous phase of which contains a determined quantity of alcohol, associated with silicate particles, it was possible to improve the results previously obtained with cosmetic products, in particular hair products, in terms of cosmetic properties and styling of the hairstyle.
• the subject of the invention is a cosmetic composition, in particular a hair composition, comprising, in a cosmetically acceptable medium of the oil-in-water emulsion type, solid particles containing at least 10% by weight of at least one silicate, characterized in that than :
• the silicate particles contain less than 1% by weight of aluminum
• Another object of the present invention consists of a method of cosmetic treatment of the hair using the composition according to the invention.

• the size can be determined, for example, by transmission electron microscopy or from the measurement of the specific surface by the BET method or else by means of a laser granulometer.
• the silicate is in the free state and does not form chemical bonds with the other fillers. It is then an alloy between the silicate and other fillers, in particular with oxides of metals or metalloids, in particular obtained by thermal fusion of these various constituents.
• the particles containing at least 10% by weight of at least one silicate further comprise a metal oxide or. of metalloid, it is chosen in particular from silicon oxide, boron, aluminum.
