Abstract

Aqueous detergent compositions giving good mildness, good lather volume and lather creaminess contain acyl isethionate, a zwitterionic detergent which is a quaternised amino acid, usually a betaine, and another anionic detergent. Proportions and ratios are specified and alkanolamides are absent or limited in amount. Incorporation of the additional anionic detergent, such as ether sulphate, has surprisingly little adverse effect and provides economy.
