    • The present invention concerns aqueous surfactant composition comprising poly hydroxy fatty acid amides of formula (A), ##STR1## wherein R.sup.2 is C.sub.11 -C.sub.19 alkyl, alkenyl or mixtures thereof, Z is a polyhydroxyhydrocarbyl moiety having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to the chain; and in a part of the total amide surfactant (a) R.sup.1 is a methyl group and in the remainder of the total amide surfactant (b) R.sup.1 is an alkyl group with from 3 to 8 carbon atoms; said composition further comprising (c) from 0% to 15% by weight of an organic solvent; wherein the ratio of N-methyl poly hydroxy fatty acid amide (a) to N-alkyl (C.sub.3 -C.sub.8) polyhydroxy fatty acid amide (b), is from 25:1 to 1:1. In a preferred embodiment of the present invention, the surfactant composition is prepared by mixing N-methyl poly hydroxy fatty acid amine and N-propyl poly hydroxy fatty acid amine, and reacting said mixture with a fatty acid ester reactant in the presence of a base catalyst and, preferably, in the presence of a reaction solvent.
    • 本发明涉及包含式(A)的多羟基脂肪酸酰胺的水性表面活性剂组合物,其中R2是C11-C19烷基,烯基或其混合物,Z是具有至少3个羟基的直链烃基链的多羟基烃基部分直接连接到 连锁,链条; 并且在总酰胺表面活性剂(a)的一部分中,R 1是甲基,在酰胺表面活性剂(b)的剩余部分中,R 1是具有3至8个碳原子的烷基; 所述组合物还包含(c)0重量%至15重量%的有机溶剂; 其中N-甲基多羟基脂肪酸酰胺(a)与N-烷基(C 3 -C 8)多羟基脂肪酸酰胺(b)的比例为25:1至1:1。 在本发明的优选实施方案中,表面活性剂组合物是通过混合N-甲基多羟基脂肪酸胺和N-丙基多羟基脂肪酸胺制备的,并在碱的存在下使所述混合物与脂肪酸酯反应物反应 催化剂,优选在反应溶剂的存在下进行。
