Abstract
The present invention is directed to cosmetic or dermatological compositions comprising, in a cosmetically acceptable aqueous medium, as an agent for coating keratin fibres, from 15 to 60% by weight of solids of a film-forming mixture comprising: (A) at least one aqueous dispersion of polymer particles which can form a film by themselves or can form a film in the presence of at least one plasticizer; the glass transition temperature Tg of the polymer or of the polymer/plasticizer mixture being less than or equal to 25.degree. C.; and (B) at least one aqueous dispersion of spherical or anisotropic, non-film-forming particles capable of forming a percolation network in the matrix of the film formed from the film-forming particles and from the optional plasticizer; the said non-film-forming particles are different from the pigments and are present in the said film-forming mixture in concentrations ranging from 20 to 90% by volume when they are spherical and in concentrations ranging from 10 to 80% by volume when they are anisotropic. These compositions can be used as bases for make-up products for the eyelashes and the eyebrows, or as bases for hair products for styling and/or maintai…
