Abstract
Abstract Skin conditioning compositions comprising an alkali metal phosphoric acid ester salt of a partial glyceride, silicone fluid, a long chain alkyl ester of a fatty acid, an emollient material, an emulsifier and water. The phosphated glyceride and the dimethicone fluid serve to provide greater retention of the conditioning composition on the skin.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
253 words
A skin conditioning composition comprising: (A) from about 0.1% to about 5% of an alkali metal phosphoric acid ester of a glyceride selected from the group consisting of a monoglyceride, a diglyceride and mixtures thereof. (B) from about 0.1% to about 5% of a non-volatile silicone fluid. (C) from about 0.1% to about 16% of an ester, or mixtures thereof, having the structural formula ##STR2## wherein R 1 and R 2 are both straight chain alkyls having from about 6 to about 22 carbon atoms and the total number of carbon atoms in the ester is at least about 24; (D) an emollient selected from the group consisting of fatty alcohols, esters having fewer than about 24 carbon atoms, branched chain esters having greater than about 24 total carbon atoms, squalane, liquid or solid paraffins, mixtures of fatty acids and squalane, mixtures of fatty acids and liquid or solid paraffins and mixtures thereof in an amount such that the amount of ester plus emollient is from about 0.2% to about 25%; (E) from about 0.05% to about 8% of an emulsifier selected from the group consisting of polyethoxylated fatty acids having less than about 30 moles of ethylene oxide per mole of fatty acid, ethoxylated esters, unethoxylated sugar esters, polyoxyethylene fatty ether phosphates, fatty acid amides, phospholipids, polypropoxylated fatty ethers, acyl lactylate salts, polyethoxylated poly (oxypropylene) glycols, polypropoxylated poly(oxyethylene) glycols, poly (oxyethylene) poly (oxypropylene) ethylene diamines, soaps, provided the level of soap is less than about 1.6%, and mixtures thereof; and (F) water.

A skin conditioning composition comprising: (A) from about 0.1% to about 5% of an alkali metal phosphoric acid ester of a glyceride selected from the group consisting of a monoglyceride, a diglyceride and mixtures thereof. (B) from about 0.1% to about 5% of a non-volatile silicone fluid. (C) from about 0.1% to about 16% of an ester, or mixtures thereof, having the structural formula ##STR2## wherein R 1 and R 2 are both straight chain alkyls having from about 6 to about 22 carbon atoms and the total number of carbon atoms in the ester is at least about 24; (D) an emollient selected from the group consisting of fatty alcohols, esters having fewer than about 24 carbon atoms, branched chain esters having greater than about 24 total carbon atoms, squalane, liquid or solid paraffins, mixtures of fatty acids and squalane, mixtures of fatty acids and liquid or solid paraffins and mixtures thereof in an amount such that the amount of ester plus emollient is from about 0.2% to about 25%; (E) from about 0.05% to about 8% of an emulsifier selected from the group consisting of polyethoxylated fatty acids having less than about 30 moles of ethylene oxide per mole of fatty acid, ethoxylated esters, unethoxylated sugar esters, polyoxyethylene fatty ether phosphates, fatty acid amides, phospholipids, polypropoxylated fatty ethers, acyl lactylate salts, polyethoxylated poly (oxypropylene) glycols, polypropoxylated poly(oxyethylene) glycols, poly (oxyethylene) poly (oxypropylene) ethylene diamines, soaps, provided the level of soap is less than about 1.6%, and mixtures thereof; and (F) water.
Claim 3
Dependent Claim
37 words

Claim 5
Dependent Claim
40 words
A skin conditioning composition according to claim 3 wherein the emulsifier is selected from the group consisting of polyethoxylated fatty acids having less than about 30 moles of ethylene oxide per mole of fatty acid ethoxylated esters and acryl lactylates.
