Abstract

Laundry detergent and cleaning compositions comprising amphiphilic graft polymers based on water-soluble polyalkylene oxides (A) as a graft base and side chains formed by polymerization of a vinyl ester component (B), said polymers having an average of ≦1 graft site per 50 alkylene oxide units and mean molar masses Mw of from 3000 to 100,000.
