Abstract

The invention relates to cosmetic compositions comprising a combination of non-emulsifying and emulsifying crosslinked siloxane elastomers.

Claims

1. A cosmetic composition comprising:

(i) from about 0.1% to about 15% of non-emulsifying crosslinked siloxane elastomer having an average particle size of at least 20 microns and a viscosity of above about 20,000 cps at 25°

C.;

(ii) from about 0.1% to about 15% of emulsifying crosslinked siloxane elastomer;

(iii) from about 10 to about 80% of a solvent for the crosslinked siloxane elastomers;

(iv) optionally, from 0 to about 50% of skin conditioning agent; and

(v) from about 0 to about 95% of water.

2. A cosmetic composition according to claim 1 wherein the skin conditioning agent is selected from the group consisting of humectants, exfoliants, emollients and mixtures thereof.

3. A cosmetic composition according to claim 2 wherein the skin-conditioning agent is a humectant.

A cosmetic composition according to claim 3 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.

5. A cosmetic composition according to claim 1 that further comprises an emulsifier.

6. A cosmetic composition according to claim 5 wherein the emulsifier is a polyoxyalkylene copolymer.

7. A cosmetic composition according to claim 6 wherein the polyoxyalkylene copolymer is dimethicone copolyol.

8. A cosmetic composition according to claim 1 that further comprises a colorant selected from the group consisting of inorganic pigments, organic pigments, lakes, dyes and toners.

9. A cosmetic composition according to claim 8 wherein the pigment is selected from the group consisting of 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, ultramarine, nylon powder, polyethylene powder, methacrylate powder, polystyrene powder, silk powder, crystalline cellulose, starch, titanated mica, iron oxide titanated mica, bismuth oxychloride, pearl, pearl mica, interference pigments and mixtures thereof.

10. A cosmetic composition according to claim 1 that further comprises a preservative.

11. A cosmetic composition according to claim 10 wherein the preservative is selected from the group consisting of disodium EDTA, phenoxyethanol, methyl paraben, propyl paraben, imidazolidinyl urea, sodium dehydroacetate, para-hydroxybenzoic acid, hydantoin derivatives, propionate salts, quaternary ammonium compounds, benzyl alcohol and mixtures thereof.

12. A cosmetic composition according to claim 1 that further comprises fillers.

13. A cosmetic composition according to claim 1 in the form of a foundation, mascara, concealer, eyeliner, brow color, eye shadow, blusher, lip paint or lipstick.
