Personal care composition comprising hydrophobic gel
View Patent ↗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.
1. 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 thc weight ratio of the alkyl dimethicone copolyol to the polyol is from about 100:1 to about 2:8;
wherein said polyol-in-silicone emulsion consists essentially of said alkyl dimethicone copolyol and said polyol.
2. The polyol-in-silicone emulsion of claim 1 , further comprising hydrophilic skin treatment agent in an amount soluble in the polyol.
3. A personal care composition comprising by weight:
(a) from about 0.01% to about 65% of the polyol-in-silicone emulsion according to claim 1 ; and
(b) a carrier.
4. The personal care composition of claim 3 wherein the composition is
an antiperspirant, wherein the carrier comprises a thickening agent, and an antiperspirant active.
5. A method of making the polyol-in-silicone emulsion according to
claim 1 comprising mixing the alkyl dimethicone copolyol with the polyol at a speed of at least about 1000 rpm and at a temperature of at least about 40° C.
6. A method of making the polyol-in-silicone emulsion according to
claim 2 comprising the steps of:
(a) mixing the polyol and the hydrophilic skin treatment agent; and
(b) mixing the alkyl dimethicone copolyol with the product of step (a) at a speed of at least about 1000 rpm and at a temperature of at least about 40° C.
