Abstract
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.
Claims16
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.
