Abstract
A skin-protecting cosmetic composition comprising a hydroxypropyl-etherified glycolipid ester represented ##STR1## wherein R.sup.1 represents a methyl group or a hydrogen atom; R.sup.2 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 11 to 15 when R.sup.1 is a methyl group, or a saturated or unsaturated hydrocarbon group having carbon atoms of 12 to 16 when R.sup.1 is a hydrogen atom; a represents the group ##STR2## R.sup.3 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 1 to 20 or --(A).sub.h H; and a, b, c, d, e, f, g and h are each integers, whose sum ranges from 1 to 60.
Claims3
