An alkylene oxide derivative represented by formula (1), wherein a ratio Mz/Mw of a weight average molecular weight (Mw) and z average molecular weight (Mz) calculated from a chromatogram obtained by gel permeation chromatography measurement of the alkylene oxide derivative satisfies formula (2) below:

[00001]$\begin{array}{cc}{Z-\left[O-{\left(PO\right)}_a-{\left(PO\right)}_b/\left(EO\right)c\right]-H]}_n& \left(1\right)\\ 5\leqq M_z/M_w\leqq 60& \left(2\right)\end{array}$

where Z, n, PO, EO, a, b and c are as defined herein; a+b+c≥10, and b/c=1/5˜5/1; (PO).sub.b/(EO).sub.c indicates that PO and EO are randomly added; and a random ratio x of PO and EO satisfies 0.1≤x≤1.
