A di(C.sub.3 -C.sub.6) alkyl sulphosuccinate may advantageously be present. An especially preferred mixture comprises di(n-octyl), (n-octyl n-hexyl) and di(n-hexyl) sulphosuccinates, and this mixture may be prepared by esterifying maleic anhydride or the like with a mixture of n-octanol and n-butanol, followed by bisulphite addition. The detergent composition is preferably in liquid form and is suitable for shampoos, fabric washing and, in particular, manual dishwashing.
