Abstract

Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.
