EXTERNAL PREPARATION FOR SKIN

摘要

Disclosed is an external preparation for the skin, which is excellent in a moisturizing effect, a skin roughness-ameliorating effect and feeling during use. The external preparation comprises a polyoxyalkylene glycol/polyethylene glycol copolymer alkyl ether derivative represented by the general formula (I): (I) wherein Y represents a residue given by removing hydroxyl groups from a polyhydric alcohol having 3 to 6 hydroxyl groups; k represents the number of hydroxyl groups in the polyhydric alcohol; EO represents an oxyethylene group; AO represents an oxyalkylene group having 3 to 4 carbon atoms; and a and b respectively satisfy the requirements shown by the formulae: 1<=a<=70 and 1<=b<=70; the ratio of the amount of the oxyethylene group to the total amount of the oxyalkylene group having 3 to 4 carbon atoms and the oxyethylene group is 20 to 100% by mass; the oxyalkylene group having 3 to 4 carbon atoms and the oxyethylene group are added randomly; and R's independently represent a hydrocarbon group having 1 to 4 carbon atoms.
