Abstract
Abstract A cosmetic composition comprising as an essential component a glycolipid ester represented by the formula, ##STR1## wherein R 1 represents a methyl group or a hydrogen atom; R 2 represents a saturated or unsaturated hydrocarbon group having 11 to 15 carbon atoms when R 1 is a methyl group, or a saturated or unsaturated hydrocarbon group having 12 to 16 carbon atoms when R 1 is a hydrocarbon atom; and R 3 represents a saturated or unsaturated hydrogen group having 1 to 20 carbon atoms is effective for skin and hair treatment.
