Abstract

A detergent composition with improved dirt-suspending power, method for its production and use of a suitable polycarboxylate for this purpose. The novel detergent contains, in addition to the customary components such as surfactant, calcium-binding silicate, etc., at least 1% by weight of a polycarboxylate with the schematic structure (X, Y, Z) in which X stands for ##STR1## Y for ##STR2## and Z for EQU --(F).sub.q --. These carboxylates can be produced from acrolein and optionally one or several comonomers by means of oxidizing radical donors without saponifying conditions and/or without subsequent Cannizzaro reaction. The novel detergents exhibits improvements over traditionally used co-builders in all essential detergent qualities. The carboxylates may be used in detergents, fine-fabric detergents, color detergents, liquid detergents and compact detergents.
