Abstract
A cosmetic composition comprising in admixture a pseudolatex containing particles of a film-forming polymer having carboxylic acid functional groups, the particles having a mean diameter of between 10 and 300 nm and at least one wax having a melting point of between 60.degree. C. and 110.degree. C. in a proportion of between 2 and 40% by weight with respect to the total weight of the composition. The carboxylic acid functional groups of the polymer are neutralized to a degree of neutralization of between 10 and 80% by a nonvolatile monobasic agent. The pseudolatex is present in a proportion of between 0.8 and 20% by way of solids with respect to the total weight of the composition. The cosmetic composition, used as a mascara, provides enhanced lengthening and beautiful curvature on eyelashes.
