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): R.sup.1 --CO--OCH.sub.2 CH(OH)CH.sub.2 OH (I) wherein R.sup.1 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): R.sup.1 --CO--OCH.sub.2 CH(OH)CH.sub.2 OH (I) wherein R.sup.1 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.
A method for increasing the foaming property of a nonionic surfactant having a straight-chain alkyl group containing from 10 to 16 carbon atoms, a polyoxyethylene or polyoxyethylene/polyoxypropylene random or block copolymer chain, an HLB value of about 13.5 or more, and an average molecular weight of from 600 to less than 5,000, which consisting essentially of mixing (b) a fatty acid monoglyceride represented by formula (I):
A low-irritating foaming composition consisting essentially of:
