摘要： Detergent compositions containing ether sulfates are provided, wherein ether sulfates are used of the formula RO--(C.sub.2 H.sub.4 O).sub.n SO.sub.3 M, wherein R is an alkyl group containing about 12 to about 15 carbon atoms or a mixture of such groups, n is a number having an average of 1-5 and M is a cation, said ether sulfate having been prepared by ethoxylating a compound ROH with epoxyethane in a manner known per se with the use of acid catalysis, followed by sulfation. Particular advantages are obtained, if the starting product ROH is an alcohol mixture containing a high percentage of branched chain compounds.

摘要： Novel surfactant compounds are provided of the formula R--CO--NH--(C.sub.2 H.sub.4 O).sub.n --CH.sub.2 COOH, wherein R--CO-- is the residue of at least one aliphatic carboxylic acid of 6-22 carbon atoms and n represents a number having an average of 2-10, as well as their salts with alkali metals, ammonium and amines. These compounds possess not only a low primary toxicity, but also a low secondary toxicity for the skin, and accordingly they are especially useful in cosmetic compositions, compositions for non-automatic dishwashing and laundering compositions for the fine laundry.
摘要翻译： 提供式R-CO-NH-（C 2 H 4 O）n -CH 2 COOH的新型表面活性剂化合物，其中R-CO-是至少一个6-22个碳原子的脂肪族羧酸的残基，n表示具有平均数 2-10，以及它们与碱金属，铵和胺的盐。 这些化合物不仅具有低的初级毒性，而且对皮肤具有低的二次毒性，因此它们特别可用于化妆品组合物，用于非常自动洗碗和用于细小衣物的洗涤组合物的组合物。
