Abstract

Provided are high slip and shine cosmetic compositions capable of forming a multilayer structure after application to a keratinous material. Certain compositions comprise (a) Component A which comprises (i) about 0.01% to 60% by weight of least one silicone-containing and/or hydrocarbon-containing film forming agent; (ii) about 0.01 to 20% by weight of at least one phenylated silicone; (iii) about 0.01 to 20% by weight of at least one siloxane polymer wax; and (b) Component B which comprises; (i) about 0.01% to 90% by weight of the composition of one or more silicone compounds in amounts sufficient to achieve a viscosity of about 1,000 cSt to 10,000,000 cSt; wherein the Component A and Component B are immiscible.

Dependent claims

A cosmetic composition that forms a multilayer structure after application to a keratinous material, the cosmetic composition comprising:

(a) Component A which comprises:
(i) about 0.01% to 60% by weight with respect to the total weight of the composition of at least one silicone-containing film forming agent having at least one glass transition temperature which is lower than normal human body temperature, wherein the at least one silicone-containing film forming agent is selected from the group consisting of a silicone resin, a silicone acrylate copolymer, and mixtures thereof;
(ii) about 0.01 to 20% by weight with respect to the total weight of the composition of at least one phenylated silicone;
(iii) about 0.01 to 20% by weight with respect to the total weight of the composition of at least one siloxane polymer wax;
and
(b) Component B which comprises:
(i) about 0.01% to 90% by weight with respect to the total weight of the composition of at least one silicone compound sufficient to achieve a viscosity of about 1,000 cSt to 10,000,000 cSt;
wherein the Component A and Component B are immiscible, the Component B has a surface energy that is lower than that of Component A, and the at least one silicone compound of Component B have a surface energy that is lower than that of the at least one silicone-containing film forming agent of Component A,
wherein the weight ratio of silicone-containing film forming agent(s) in Component A to silicone compound(s) in Component B is from about 1:50 to 50:1, and
wherein the cosmetic composition forms a multilayer structure after application to a keratinous material.
