Abstract
The invention relates to copolymers as ingredients for detergents and cleaning agents, which contain monoethylenically unsaturated mono- and dicarboxylic acids, their hydroxyalkyl esters and, if appropriate, other ethylenically unsaturated compounds as monomer units, and are distinguished by a particular calicum-binding and magnesium-binding capacity, detergents and cleaning agents containing these copolymers, and their use in detergents and cleaning agents, in particular as sequestering agents and anti-redeposition agents.
