A skin treatment composition of the present invention is an external composition for skin comprising an alkylene oxide derivative expressed by Formula (I): n R 1 O—[(AO) m (EO) n ]—R 2 (I) n wherein AO is an oxyalkylene group of C 3 or C 4 ; EO is an oxyethylene group; m and n are 1≦m≦70 and 1≦n≦70 respectively, wherein EO is 20˜80% by weight with respect to a total of AO and EO; each of R 1 and R 2 is a hydrogen or a hydrocarbon group having C 1-4 . The alkylene oxide derivative (I) has a moisturizing effect, a rough skin improving effect, a stickiness improving effect, and a transdermal absorption promoting effect. When a refreshing agent is used together therewith in the composition of the present invention, the refreshing effect lasts for a long time and it is excellent in feeling of use without skin stimulation. |
