Abstract (en)
[origin: DE19905393A1] The invention relates to the use of cross-linked polymers which have a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution) and which contain polymerised monoethylenic unsaturated monomers that contain acid groups and/or the alkali salts or ammonium salts thereof and optionally additional polymerised monoethylenic unsaturated monomers. Said cross-linked polymers are used as an additive for compact, particle-shaped washing and cleaning agents for increasing the disintegration rate when being brought into contact with water. The invention also relates to the use of compact, particle-shaped washing and cleaning agents which contain cross-linked polymers with a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution).
