Abstract (en)

[origin: EP1036839A2] Use is claimed of crosslinked polyvinyl pyrrolidone (PVP) particles, of size 50-400 mu , as additives for compacted particulate detergents to increase the disintegration rate when the detergent comes in contact with water. Independent claims are also included for: (i) compacted particulate detergent compositions containing 0.5-20 wt.% of the PVP additive particles of size 50-400 mu with at least 10 wt.% below 200 mu ; and (ii) production of such compositions containing the PVP disintegrating agent by mixing the PVP particles with powdered detergent ingredients and compacting the mixture.
