Title:
USE OF CROSS-LINKED POLYMERS FOR INCREASING THE DISINTEGRATION RATE OF COMPACT, PARTICLE-SHAPED WASHING AND CLEANING AGENTS
Document Type and Number:
WIPO Patent Application WO2000047704
Kind Code:
A3
Abstract:
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).
