摘要:
A base for a skin external composition comprises, as a main ingredient, an alkylene oxide derivative represented by the following formula (I):
R 1 O-[(AO) m (EO) n ]-R 2 (I)
wherein AO is an oxyalkylene group having a carbon number of 3 to 4; EO is an oxyethylene group; and R 1 and R 2 may be the same or different, and are a hydrocarbon group having a carbon number of 1 to 4, or a hydrogen atom. The base is a water-soluble base that can exert both of the smooth feeling and the moist feeling.
