In a method of manufacturing fatty acid esters of polyoxyalkylene alkyl ethers, fatty acid alkyl ester is reacted with alkylene oxide in the presence of a catalyst consisting essentially of a magnesium oxide added with at least one metal ion selected from the group consisting of Al3+, Ga3+, In3+, Tl3+, Co3+, Sc3+, La3+, and Mn2+ to manufacture a compound having the following formula: <IMAGE> wherein each of R1 and R3 independently represents an alkyl group, R2 represents an alkylene group, and n is a positive integer.
