ABSTRACT A detergent composition with especially good foaming properties includes a di(C7-C9) alkyl sulphosuccinate, preferably a di(C8 alkyl) sulphosuccinate, and an unsymmetrical dialkyl sulphosuccinate in which one alkyl group is C7-C9 and the other is C3-C6, preferably a (C6 alkyl) (C8 alkyl) sulphosuccinate. A di(C3-C6) 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 inter alia for shampoos, fabric washing and, in particular, manual dishwashing.
