Abstract

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.
