Cosmetic or dermatological composition in an aqueous medium comprising a film-forming oligomer and rigid, non-film forming nanometric particles and uses thereof

The present invention relates to cosmetic or dermatological compositions comprising, in a cosmetically acceptable aqueous medium, at least one film-forming oligomer which is soluble or dispersible in the said medium, and at least one type of rigid, non-film-forming nanometric, i.e., average particle size of less than or equal to 1 m, particles dispersed in the said medium, as well as to their uses in the cosmetics or dermopharmacy field, in particular in products for maintaining the hairstyle, products for coating the eyelashes and eyebrows, and nail make-up and/or care products. Cosmetic compositions containing in a cosmetically acceptable medium(A) at least one film-forming oligomer having a molecular weight, measured by steric exclusion chromatography, of less than or equal to 50,000, the at least one film-forming oligomer being soluble or dispersible in the cosmetically acceptable medium; and(B) rigid, non-film-forming particles of average size less than or equal to 1 m, the rigid, non-film forming particles being dispersed in the cosmetically acceptable medium. The compositions may be used, for example, as product bases for maintaining the hairstyle, as products for coating the eyelashes and the eyebrows or as nail make-up and/or care products.
