Silicone elastomer emulsion cosmetic composition comprising colorant inclusive internal phase
View Patent ↗The present invention relates to silicone elastomer emulsion cosmetic compositions that comprise an internal phase the further includes a colorant. These compositions are intended to deliver such colorant ingredients to the skin of the user in such a manner as to provide a smooth and even colored appearance. In particular, the present invention relates to a cosmetic composition comprising an emulsion that further comprises: a) a continuous aqueous phase comprising: 1) from about 0.1% to about 10%, by weight of the composition, of a non-emulsifying crosslinked siloxane elastomer; b) a dispersed oil phase comprising: 1) from about 1% to about 25%, by weight of the composition, of an oil compatible colorant; and 2) from about 0.01% to about 20%, by weight of the composition, of a binder; and c) from about 0.01% to about 15%, by weight of the composition, of an emulsifier.
1. A cosmetic composition comprising an oil-in-water emulsion that further comprises:
a) a continuous aqueous phase comprising:
1) from about 0.1% to about 10%, by weight of the composition, of a non-emulsifying crosslinked siloxane elastomer swelled in a non-polar solvent;
b) a dispersed oil phase comprising:
1) from about 1% to about 25%, by weight of the composition, of an oil compatible colorant; and
2) from about 0.01% to about 20%, by weight of the composition, of a binder; and
c) from about 0.01% to about 15%, by weight of the composition, of an emulsifier.
2. The cosmetic composition of claim 1 wherein the composition further comprises a skin conditioning agent that is selected from the group consisting of humectants, exfoliants, emollients and mixtures thereof.
3. The cosmetic composition of claim 2 wherein the humectant is selected from the group consisting of propylene glycol, dipropylene glycol, polypropylene glycol, polyethylene glycol, sorbitol, hydroxypropyl sorbitol, hexylene glycol, glycerin, 1,3-butylene glycol, 1,2,6-hexanetriol, ethoxylated glycerin, propoxylated glycerin and mixtures thereof.
4. The cosmetic composition of claim 3 wherein the skin-conditioning agent is an emollient selected from the group consisting of hydrocarbons, fatty acids, fatty alcohols and esters, and combinations thereof.
5. The cosmetic composition of claim 1 wherein the emulsifier is selected from the group consisting of polyoxyalkylene copolymers, emulsifying crosslinked siloxane elastomers, and combinations thereof.
6. The cosmetic composition of claim 1 wherein said oil compatible colorant is selected from the group consisting of hydrophobically treated talc, mica, magnesium carbonate, calcium carbonate, magnesium silicate, aluminum magnesium silicate, silica, titanium dioxide, zinc oxide, red iron oxide, yellow iron oxide, black iron oxide, titanated mica, iron oxide titanated mica, bismuth oxychloride, and combinations thereof.
7. The cosmetic composition of claim 1 in a product form selected from the group consisting of foundations, mascaras, concealers, eyeliners, brow colors, eye shadows, blushers, lip paints, lip glosses, lipsticks, and combinations thereof.
8. The cosmetic composition of claim 1 wherein said composition further comprises an active selected from the group consisting of a sunscreen active, a shine control agent, and combinations thereof.
9. A method of providing a natural and radiant appearance to mammalian skin wherein said method comprises the step of topically applying the composition of claim 1 to mammalian skin.
10. A method of providing UV protection to mammalian skin wherein said method comprises the step of topically applying the composition of claim 1 to mammalian skin.
