Abstract

Disclosed are cosmetic compositions comprising: PA1 (a) from about 0.1% to about 50%, based on the weight of the composition, of a film-forming graft copolymer, wherein the copolymer comprises: PA2 (i) a backbone exhibiting a T.sub.g of from about 0.degree. C. to about 50.degree. C.; and PA2 (ii) one or more hydrophilic grafts attached to the backbone wherein each of the grafts exhibits a T.sub.g of from about 50.degree. C. to about 200.degree. C., and wherein the average molecular weight of each of the grafts is greater than about 1000; and PA1 (b) from about 50% to about 99.9%, based on the weight of the composition, of a suitable carrier. The compositions provide good wear properties and are suitable for use in a variety of cosmetic applications, such as facial moisturizers, foundations, lipsticks, mascaras, nail polishes and the like. In a preferred embodiment, the compositions are in the form of a nail polish which, when applied to nails, exhibit excellent long wear properties.
