Abstract
Abstract A skin-protecting cosmetic composition comprising a hydroxypropyl-etherified glycolipid ester represented ##STR1## wherein R 1 represents a methyl group or a hydrogen atom; R 2 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 11 to 15 when R 1 is a methyl group, or a saturated or unsaturated hydrocarbon group having carbon atoms of 12 to 16 when R 1 is a hydrogen atom; a represents the group ##STR2## R 3 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 1 to 20 or --(A) h H; and a, b, c, d, e, f, g and h are each integers, whose sum ranges from 1 to 60.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
A skin protecting cosmetic composition in emulsion or solution form of from 0.1 to 100% of a hydroxypropyl-etherified glycolipid ester represented by the formula: ##STR7## wherein R 1 represents methyl or hydrogen; R 2 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 11 to 15 when R 1 is methyl, or a saturated or unsaturated hydrocarbon group having carbon atoms of 12 to 16 when R 1 is a hydrogen atom; A represents the Group ##STR8## R 3 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 1 to 20 or--(A) h H; and a, b, c, e, d, f, g and h are each integers, whose sum ranges from 1 to 60, as the oil component, in an aqueous vehicle.
Claim 2
Dependent Claim
126 words
