A basic agent for use in cosmetics comprising an alkylene oxide derivative represented by the following formula (I) is provided:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒZ-{O(AO) l (EO) m - (BO) n H} a €ƒ€ƒ€ƒ€ƒ€ƒ(I)
(where Z represents a residue of a compound having 3 to 9 hydroxyl groups with the hydroxyl groups removed, a is from 3 to 9, AO represents an oxyalkylene group of 3 to 4 carbon atoms, EO represents oxyethylene group, l and m represent average additional mol numbers of the oxyalkylene groups of 3 to 4 carbon atoms and the oxyethylene groups, respectively, and 1 ‰¦1 ‰¦50, 1 ‰¦ m ‰¦50, the weight ratio (AO/EO) of AO to EO is from 1/5 to 5/1, AO and EO may be added in a random form or may be added in a block form. BO represents oxyalkylene group with a number of carbon atoms of 4, and n is an average additional mol number and 0.5 ‰¦ n ‰¦ 5). |
