    • 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.
    • 公开了一种提高含有10〜16个碳原子的直链烷基,HLB值约为13.5以上的非离子性表面活性剂的发泡性的方法,该方法包括:(b)以(b)表示的脂肪酸单甘油酯 式(I):其中R 1表示具有9至15个碳原子的直链烷基的R1-CO-OCH2CH(OH)CH2OH(Ⅰ),(a)(b)/(a)中的非离子表面活性剂, 重量比为2/8至6/5。 还公开了一种低刺激性发泡组合物,其包含(a)具有含有10至16个碳原子的直链烷基作为疏水基团,HLB值为约13.5或更高的非离子表面活性剂和(b) 由式(I)表示的脂肪酸单甘油酯:(b)/(a)重量比的R 1 -CO-OCH 2 CH(OH)CH 2 OH(I)其中R 1表示具有9至15个碳原子的直链烷基 为2/8至6/5。
