  • Patent number: 7709015
    Abstract: Disclosed is a polyol-in-silicone emulsion consisting essentially of: (i) an alkyl dimethicone copolyol having an HLB of from about 4 to about 6, and a molecular weight of from about 10,000 to about 20,000, wherein the alkyl group is made of about 10 to about 22 carbons; and (ii) a polyol, wherein the weight ratio of the alkyl dimethicone copolyol to the polyol is from about 100:1 to about 2:8; methods to make such a polyol-in-silicone emulsion, as well as an anhydrous personal care composition comprising by weight: (a) from about 0.01% to about 15% of an alkyl dimethicone copolyol having an HLB of about 4-6, and a molecular weight of from about 10,000 to about 20,000, wherein the alkyl group is made of about 10 to about 22 carbons; (b) from about 0.01% to about 35% of a polyol, wherein the weight ratio of the alkyl dimethicone copolyol to the polyol is from about 100:1 to about 2:8; and wherein the composition is substantially free of water.
