Abstract
An anhydrous cosmetic composition comprising, by weight of the total composition, 1-50% of a polar, emulsifying siloxane elastomer, 0.01-40% particulate material; and 1-70% of a nonpolar oil; an anhydrous cosmetic composition comprising an emulsifying siloxane elastomer and an incompatible nonaqueous polar ingredient, wherein the emulsifying siloxane elastomer is present in an amount sufficient to render the incompatible nonaqueous polar ingredient compatible in the anhydrous cosmetic composition; and a method for preparing stable, anhydrous cosmetic compositions comprising at least one incompatible nonaqueous polar ingredient, comprising adding to the anhydrous composition an emulsifying siloxane elastomer in an amount sufficient to cause the incompatible nonaqueous polar ingredient to become compatible in the anhydrous cosmetic composition.
