The present invention provides a novel compound, which acting as a component having a good skin roughness-improving effect, providing good safty and good sense of use, especially free from a sticky sense, a good moisture keeping ability, and increasing the stability of the base. The alkylene oxide derivative is represented by the following general formula (I): Z-{O-[(AO)a-(EO)b]-R}2 (I) wherein Z is a residue of a dimerdiol, which hydroxyl group being removed; EO is oxyethylene group; AO is C3-4 oxyalkylene group; the adducted type of these groups is block type. a and b respectively represents the average adduct moles of the oxyalkylene group and oxyethylene group, 1 ≤ 2a ≤ 150 and 1 ≤ 2b ≤ 150, the ratio of oxyethylene group to the total amount of C3-4 oxyalkylene group and oxyethylene group is 10 to 90 mass%; R is same or different, representing C1-4 hydrocarbon group. |
