Abstract
A mascara composition for curling and thickening eyelashes comprising: PA1 a waxes-in-water emulsion of at least one mixture of hard waxes (I), the mixture of waxes (I) containing at least three waxes having melting points ranging from 77.degree. C. to 110.degree. C., the mixture of waxes (I) is present in a content of at least 10% by weight relative to the total weight of the composition, and the mixture of waxes (I) is in the form of particles of at least 1 .mu.m in size, and PA1 at least 0.1% by weight of a polymer system containing at least one film-forming polymer, where the polymer system is capable of forming a film which produces, at a concentration of 7% in water, a greater than 1% retraction of isolated stratum corneum at 30.degree. C. and under a relative humidity of 40%.
