Novel polyether carboxylic acid derivatives, as well as their uses

摘要

Novel surfactant compounds are provided of the formula R-CO-NH-(C2H4O)n-CH2COOH, 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.
