Cosmetic compositions capable of forming a multilayer structure after application to a keratinous material

A cosmetic composition capable of forming a multilayer structure after application to skin,

• wherein the cosmetic composition comprises at least two immiscible components:
• Component A which 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 having at least one glass transition temperature which is lower than normal human body temperature;
• and
• Component B which comprises about 0.01% to 90% by weight with respect to the total weight of the composition of one or more silicone compounds in amounts sufficient to achieve a viscosity of about 1,000 cSt to 22,000,000 cSt,
• wherein the weight ratio of the silicone- and/or hydrocarbon-containing film forming agent(s) in Component A to silicone compound(s) in Component B is from about 1:50 to 1.5:1, and
• wherein, prior to application to skin, the cosmetic composition is mixed such that Component A and Component B are temporarily miscible upon application to skin and, after application to skin, Component A separates from Component B to form a multilayer structure on skin comprising Layer A corresponding to Component A and Layer B corresponding to Component B.
