Abstract

Disclosed is a lipophilic personal care composition comprising by weight: (a) from about 5% to about 50% of a polyglycerin fatty acid ester having a polyglycerin of 2- 15 units and at least 5 fatty acid residues attached thereto, wherein the fatty acid residue has 18 to 24 carbons; (b) from about 5% to about 50% of an N-long chain acyl acidic amino acid ester of sterol having formula (I): XOC(O)-(CH2)n-CH(NHCOR)-C(O)OY (I) wherein one of X and Y is an ester residue of sterol selected from the group consisting of phytosterol, cholesterol, lanosterol, stigmasterol, its hydrogenates, and its derivatives, and the other is selected from H, an alkyl or alkenyl of 8-30 carbons, and ester residue of monohydric solid alcohol of 12-38 carbons; COR is a long chain acyl group of 8-22 carbons; and n is an integer of 1 or 2; and having a water holding capability of at least 400%, and is liquid at 25 DEG C; and (c) from about 5 % to about 50% of a dimer acid ester.

Description

field of invention [0001] The present invention relates to lipophilic personal care compositions comprising polyglycerol fatty acid esters, N-long chain acyl acidic amino acid esters of sterols, and dimer esters. The compositions are especially useful for the manufacture of cosmetic compositions such as lipsticks, lip balms, foundations and creams. Background of the invention [0002] Recently, the lipstick market has been segmented into those consumers looking for wear benefits, moisturizing benefits, and balanced wear and moisturizing benefits. Lipsticks are mainly made of lipophilic or hydrophobic materials. Lipsticks designed to provide moisturizing benefits to the lips also tend to contain polar solvents or other moisturizing components that are more or less hydrophilic. The use of association and gel structures has been proposed to bind the aforementioned polar solvents in the lipophilic base of lipsticks, as described in PCT publication WO 02 / 26198. While such lips...
