A method for improving the foaming property of a nonionic surfactant having a straight-chain alkyl group containing from 10 to 16 carbon atoms, and an HLB value of about 13.5 or more is disclosed, which comprises adding (b) a fatty acid monoglyceride represented by formula (I):R1-CO-OCH2CH(OH)CH2OH(I)wherein R1 represents a straight-chain alkyl group having from 9 to 15 carbon atoms, to (a) the nonionic surfactant in a (b)/(a) weight ratio of from 2/8 to 6/5. A low-irritating foaming composition is also disclosed, which comprises (a) a nonionic surfactant having a straight-chain alkyl group containing from 10 to 16 carbon atoms as a hydrophobic group, and an HLB value of about 13.5 or more and (b) a fatty acid monoglyceride represented by formula (I):R1-CO-OCH2CH(OH)CH2OH(I)wherein R1 represents a straight chain alkyl group having from 9 to 15 carbon atoms, in a (b)/(a) weight ratio of from 2/8 to 6/5.
