Surfactant composition.

摘要

A surfactant composition containing a fatty acid polyoxyalkylene lower alkyl ether represented by formula (1): R(OR<1>)nOR<2> (1> wherein R represents an alkanoyl or alkenoyl group having from 10 to 18 carbon atoms; R<1> represents an alkylene having from 2 to 4 carbon atoms; R<2> represents a lower alkyl group; and n is from 5 to 100 on the average; and a fatty acid monoglyceride represented by formula (2): R<3>OCH2CH(OH)CH2OH (2> wherein R<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).
