PROBLEM TO BE SOLVED: To use a crosslinked polyvinylpyrrolidone so as to increase the disintegration rate of a compact granulated detergent and cleanser when contacted with water, by utilizing crosslinked polyvinylpyrrolidone particles each with a specific diameter. SOLUTION: Crosslinked polyvinylpyrrolidone particles each with a diameter of 50-400 μm, preferably 80-300 μm are used as an additive so as to increase the disintegration rate of a compact granulated detergent and cleanser when contacted with water. The compact granulated detergent and cleanser mean particles exhibiting detergent and cleanser activities, especially pellets, e.g. (dishwasher) detergent pellets, bleaching agent pellets, or detergent pellets for clothing especially for domestic use, more especially in a washer. It is desirable that at least 10 wt.%, preferably 15 wt.%, more preferably 25 wt.% of the crosslinked polyvinylpyrrolidone particles have each a diameter of

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).
