1. A cosmetic composition capable of forming a multilayer structure after application to a keratinous material, wherein the cosmetic composition comprises at least two immiscible components A and B prior to application and wherein Component A and Component B are separated in the cosmetic composition prior to application: wherein component A comprises at least one MQ resin, at least one polypropylsilsesquioxane, and at least one modified MQ resin, wherein the at least one modified MQ resin is polymethylsilsesquioxane/trimethylsiloxysilicate and wherein the at least one MQ resin is trimethylsiloxysilicate; and wherein component B comprises about 0.01% to 90% by weight with respect to the total weight of the composition of one or more silicone compounds in an amount sufficient to achieve a viscosity of about 1,000 cSt to 22,000,000 cSt, 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, wherein the at least one MQ resin, the at least one polypropylsilsesquioxane, and the at least one modified MQ resin are present in the composition in a weight ratio of (1) the at least one MQ resin and the at least one polypropylsilsesquioxane to (2) the at least one modified MQ resin from about 2:1 to about 1:3.
