Abstract: A cosmetic composition which provides a semi-permanent, crosslinked film on a keratinous substrate, comprising a film-forming polymer having functional groups capable of cross-inking upon exposure to a cross-linking agent reactive with said functional groups; a cross-linking agent reactive with said functional groups of the film-forming polymer; a dissipatable blocking agent which is operable prior to dissipation, to block the cross-linking agent from cross-linking the functional groups of the film-forming polymer, and which, after dissipation, leaves the cross-linking agent free to cross-link the functional groups of the film-forming polymer.

Abstract: A cosmetic composition comprising an oil component and a particulate matter component, the improvement wherein the composition additionally contains an uncrosslinked synthetic polymer comprising a first repeat unit selected from the group consisting of methacrylate ester monomers which, if polymerized, would yield a polymer having a glass transition temperature of -10 to 75.degree. C.; and a second repeat unit selected from the group consisting of methacrylate ester monomers which, if polymerized, would yield a polymer having a glass transition temperature in the range of about 76 to 120.degree. C., the synthetic polymer having a glass transition temperature ranging from about 20 to 105.degree. C.
