Abstract

A stable personal care composition in the form of a water-in-oil emulsion may comprise a silicone elastomer comprising a polyalkyl ether pendant or a polyalkyl ether crosslink, wherein the alkyl group contains three or more carbon atoms; a non-emulsifying silicone elastomer; an emulsifier; a polar oil; and water. The personal care composition allows for previously unattainable levels of polar oils and/or aqueous phase within a water-in-oil emulsion.
