Low viscosity, unstable water-in-silicone emulsion cosmetic compositions and methods of use thereof
A low viscosity, unstable water-in-silicone emulsion cosmetic composition stabilized upon agitation comprising a volatile solvent, a water phase dispersed within the composition, at least one silicone film-forming polymer and at least one emulsifier, and methods of use thereof as a sprayable composition.
1. A water-in-silicone emulsion cosmetic composition stabilized upon agitation comprising:
from about 15% to about 80% by weight of a volatile solvent selected from the group consisting of volatile dimethicone, isododecane, isohexadecane, isoeicosane, isooctane, cyclomethicone and mixtures thereof;
from about 1% to about 20% by weight of a water phase dispersed within the composition;
from about 2% to about 20% by weight of at least one silicone film-forming polymer selected from the group consisting of dimethicone/silylate isododecane and poly(dimethylsiloxane)-g-poly(isobutyl methacrylate); and
from about 0.01% to about 15% by weight of at least one emulsifier selected from the group consisting of water-in-oil emulsifiers, silicone-based emulsifiers, and mixtures thereof, wherein said emulsifier has a viscosity ranging from about 4 cps to about 1600 cps,
wherein the emulsion has a viscosity ranging from about 200 cps to about 1200 cps, and wherein the emulsion cannot remain in a stable two phase system and instead separates into visually distinct layers without the aid of agitation.
2. The composition of claim 1 wherein the silicone film-forming polymer is dimethicone/silylate isododecane.
3. The composition of claim 1 wherein the emulsifier is selected from the group consisting of a mixture of Cetyl PEG/PPG-10/Dimethicone and a mixture of Cetyl Dimethicone Copolyol, Polyglyceryl 4-Isostearate and Hexyl Laurate.
4. The composition of claim 1 wherein the volatile solvent is isododecane.
5. A kit for providing a sprayable make-up composition comprising: a spray applicator; and a composition as described in claim 1 .
6. The kit of claim 5 wherein the spray applicator comprises a spray gun attached to an air compressor.
7. The kit of claim 5 wherein the silicone film-foorming polymer is dimethicone/silylate isododecane.
8. The kit of claim 5 wherein the emulsifier is selected from the group consisting of a mixture of Cetyl PEG/PPG-10/Dimethicone and a mixture of Cetyl Dimethicone Copolyol, Polyglyceryl 4-Isostearate and Hexyl Laurate.
9. The kit of claim 5 wherein the volatile solvent is isododecane.
10. A system for applying a skin care composition to human skin comprising: a water-in-silicone emulsion cosmetic composition according to claim 1 ; and an applicator for applying the composition to the skin.
11. The system of claim 10 wherein the silicone film-forming polymer is dimethicone/silylate isododecane.
12. The system of claim 10 wherein the emulsifier is selected from the group consisting of a mixture of Cetyl PEG/PPG-10/Dimethicone and a mixture of Cetyl Dimethicone Copolyol, Polyglyceryl 4-Isostearate and Hexyl Laurate.
13. The system of claim 10 wherein the volatile solvent is isododecane.
14. The system of claim 10 wherein the applicator is a spray gun.
15. A water-in-silicone emulsion cosmetic composition stabilized upon agitation comprising:
from about 15% to about 80% by weight of isododecane;
from about 1% to about 20% by weight of water dispersed within the composition;
from about 2% to about 20% by weight of dimethicone/silylate isododecane; and
from about 0.01% to about 15% by weight of at least one emulsifier selected from the group consistinng of a mixture of Cetyl PEG/PPG-10/Dimethicone and a mixture of Cetyl Dimethicone Copolyol, Polyglyceryl 4-Isostearate and Hexyl Laurate.
16. A system for applying a skin care composition to human skin comprising: a water-in-silicone emulsion cosmetic composition according to claim 15 ; and an applicator for applying the composition to the skin.
