Abstract
Abstract A powdered compressed cosmetic material comprising a hydroxypropyl-etherified glycolipid ester represented by the general formula; ##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 R 2 represents 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 integers, whose sum ranges from 1 to 6.
