摘要

This alkylene oxide derivative is represented by formula (1), wherein a ratio Mz/Mw between the z-average molecular weight (Mz) and the weight average molecular weight (Mw) calculated from a chromatogram obtained through a gel permeation chromatography measurement satisfies the relationship of formula (2). Formula (1): Z-[O-(PO)_a-(PO)_b/(EO)_c]-H]_n (Z represents a residue resulting from removing all hydroxyl groups from a compound having 1-24 carbon atoms and 1-6 hydroxyl groups, n represents a number of 1-6, PO represents an oxypropylene group, EO represents an oxyethylene group, a and b each represent an addition mole number of PO, a represents a number of 1-100, b represents a number of 1-100, c represents a number of 1-200, a+b+c≥10 and b/c=1/5 to 5/1 are both satisfied, (PO)_b/(EO)_c indicates that PO and EO are randomly added, and the randomness rate x of PO and EO satisfies 0.1≤x≤1. Formula (2): 5≤M_z/M_w≤60
