Abstract
Abstract @ Novel surfactant compounds are provided of the formula R-CO-NH-(C 2 H 4 O) n -CH 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 value 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.
