A surfactant-based detergent contains water-soluble copolymers which contain (a) from 99.5 to 15 mol % of one or more monoethylenically unsaturated C3- to C6-monocarboxylic acids, (b) from 0.5 to 20 mol % of one or more comonomers which contain two or more ethylenically unsaturated nonconjugated dou

A surfactant-based detergent contains water-soluble copolymers which contain (a) from 99.5 to 15 mol % of one or more monoethylenically unsaturated C3- to C6-monocarboxylic acids, (b) from 0.5 to 20 mol % of one or more comonomers which contain two or more ethylenically unsaturated nonconjugated double bonds and have one or more －CO－OX groups where X is hydrogen, an alkali metal, one equivalent of an alkaline earth metal or ammonium, (c) from 0 to 84.5 mol % of one or more monoethylenically unsaturated C4- to C6-dicarboxylic acids, (d) from 0 to 20 mol % of one or more hydroxyalkyl esters of monoethylenically unsaturated C3- to C6-carboxylic acids and (e) from 0 to 30 mol % of other water-soluble monoethylenically unsaturated monomers copolymerizable with (a) to (d) as copolymerized units, with the proviso that the sum of the mol % ages (a) to (e) is always 100 and which have a Finkentscher K value of from 8 to 120.
