Abstract:
A cosmetic or dermatological composition comprising, in a cosmetically acceptable aqueous medium, as an agent in said composition for coating keratin fibres, from 15 to 60% by weight of solids of at least one film-forming mixture comprising:(A) at least one aqueous dispersion of film-forming polymer particles, optionally including at least one plasticizer, wherein said film-forming polymer particles alone or said film-forming polymer particles combined with said optional at least one plasticizer have a glass transition temperature Tg no greater than 25.degree. C.; and(B) at least one aqueous dispersion of spherical or anisotropic, non-film-forming particles in an amount effective to form a percolation network in the matrix formed from said at least one aqueous dispersion of film-forming polymer particles (A);wherein said non-film-forming particles are not pigments and are present in said at least one film-forming mixture in an amount ranging from 20 to 90% by volume when said non-film-forming particles are spherical and in an amount ranging from 10 to 80% by volume when said non-film-forming particles are anisotropic.
