Abstract

The agents contain 5-70 % by weight of at least one surfactant, 0.1-50 % by weight of at least one builder and customary detergent auxiliaries and have the following builder contents: a) 0.1-25 % by weight of a copolymer obtainable by copolymerisation known per se of the following monomers: aa) 40-99.9 mol% of ethylenically unsaturated carboxylic acids or the alkali metal salts thereof, of the general formula R<1>(R<2>)C=C(R<3>)COOX, in which X = H, alkali metal R<2> = H, COOX, C1-C4-alkyl, C5-C8-cycloalkyl, phenyl or substituted phenyl R<1>, R<3> = H, C1-C4-alkyl, C5-C8-cycloalkyl, phenyl, substituted phenyl or the anhydrides thereof bb) 0.1-40 mol% of ethylenically unsaturated phosphonic acids or the alkali metal salts thereof, of the general formula R<4>(R<5>)C=C(R<6>)PO3X2, in which X = H, alkali metal R<4>, R<5> = H, C1-C4-alkyl, C5-C8-cycloalkyl, phenyl, substituted phenyl R<6> = C1-C4-alkyl, C5-C8-cycloalkyl, phenyl, substituted phenyl cc) 0-20 mol% of olefinically unsaturated compounds without carboxylic or phosphonic acid groups b) 0-49.9 % by weight of customary builders. The copolymer is used as builder or builder additive in washing and cleaning agents.
