1. A cosmetic composition capable of forming a multilayer structure after application to a keratinous material comprising at least two immiscible components prior to application, wherein the at least two immiscible components are Component A and Component B and Component A and Component B are separated in the cosmetic composition,
wherein component A comprises about 0.01% to 60% by weight with respect to the total weight of the composition of at least one silicone and/or hydrocarbon-containing film-forming agent selected from the group consisting of a film forming agent selected from the group consisting of silicone-containing film forming agents, polysaccharides, high viscosity esters, polybutenes, polyisobutenes, polyhydrogenated butenes, acrylic polymers, acrylate copolymers, vinyl pyrrolidone containing homopolymers and copolymers, polyurethanes, polyolefins, and mixtures thereof;
wherein component B comprises one or more silicone compounds selected from the group consisting of dimethicone, dimethiconol, cyclopentasiloxane, diisostearoyl trimethylolpropane siloxy silicate, diphenyl dimethicone, and mixtures thereof; and
wherein, prior to application to keratinous material, the cosmetic composition is mixed such that Component A and Component B are temporarily miscible upon application to keratinous material and, after application to keratinous material, Component A separates from Component B to form a multilayer structure on keratinous material comprising Layer A corresponding to Component A and Layer B corresponding to Component B.
