An amide derivative represented by the following general formula (I) or (II): ##STR1## (wherein R.sup.1 and R.sup.2 represent each a straight-chain or branched, saturated or unsaturated hydrocarbon group provided that one of them carries 26 to 39 carbon atoms while the other carries 9 to 39 carbon atoms); or ##STR2## (wherein R.sup.3 represents a straight-chain or branched, saturated or unsaturated hydrocarbon group carrying 10 to 40 carbon atoms; R.sup.4 represents a straight-chain or branched hydrocarbon group carrying 3 to 39 carbon atoms; and R.sup.5 represents a dydrogen atom, a straight-chain or branched, saturated or unsaturated hydrocarbon group carrying 10 to 40 carbon atoms or an acyl group);and a dermatologic preparation containing the same.
摘要:
A novel alcohol-modified silicone ester derivative of the following formula (I): ##STR1## wherein R is a saturated or unsaturated, linear, branched or cyclic aromatic residual or hydrocarbon group; a, b and c are numbers which sum falls in the range from 0 to 130; d is a number lying between 0 and 1; and 1, m and n are numbers which sum falls in the range from 0 to 6.Cosmetic compositions containing the above silicone ester derivative (I) were also disclosed.The silicone ester derivative (I) is useful as a cosmetic ingredient due to the capability of improving feel on use.
