Abstract

A detergent composition contains as essential ingredients surfactants and from 0.1 to 15% by weight of water-soluble or -dispersible polymers obtainable by oxidation of polymers containing not less than 10 mol % of carboxyl-containing monoethylenically unsaturated monomers as copolymerized units and having Fikentscher K values of from 8 to 300.
