PROBLEM TO BE SOLVED: To provide a cosmetic base which has both excellent touch and excellent moisturizing properties and keeps the skin moist even after being washed off and to provide a cosmetic formulated therewith. SOLUTION: The cosmetic base comprises an alkylene oxide derivative represented by formula (I): Z-äO(AO)<SB>l</SB>(EO)<SB>m</SB>-(BO)<SB>n</SB>R}<SB>a</SB>(I) (wherein Z is the residue derived by removing the hydroxy groups from a compound having 3 to 9 hydroxy groups; a is 3 to 9; AO is a 3C or 4C oxyalkylene group; EO is an oxyethylene group; l and m, each of which is the average of the number of moles of 3C or 4C oxyalkylene groups or oxyethylene groups added, are in the ranges: 1≤l≤50 and 1≤m≤50; the weight ratio of AO to EO (AO/EO) is 1/5 to 5/1; AOs and EOs are randomly added to each other; BO is a 4C oxyalkylene group; n, which is the average of the number of moles of the 4C oxyalkylene groups added, is in the range: 0.5≤n≤5; and R is a 1 to 4C hydrocarbon group).
