    摘要: A surfactant composition containing a fatty acid polyoxyalkylene lower alkyl ether represented by formula (1):R(OR.sup.1).sub.n OR.sup.2 (1)wherein R represents an alkanoyl or alkenoyl group having from 10 to 18 carbon atoms;R.sup.1 represents an alkylene having from 2 to 4 carbon atoms;R.sup.2 represents a lower alkyl group; andn is from 5 to 100 on the average; and a fatty acid monoglyceride represented by formula (2):R.sup.3 OCH.sub.2 CH(OH)CH.sub.2 OH (2)wherein R.sup.3 represents an alkanoyl group having from 8 to 16 carbon atoms or an alkenoyl group having from 12 to 22 carbon atoms;are disclosed.The foaming properties of a fatty acid polyoxyalkylene lower alkyl ether of formula (1) are improved by adding a fatty acid monoglyceride represented by formula (2) to the fatty acid polyoxyalkylene lower alkyl ether of formula (1).
