Abstract
Hydrophobically modified vinyl pyrrolidone polymers which are copolymers having a vinyl pyrrolidone backbone and pendant hydrophobic side chains are useful in laundry detergent compositions to improve detergency and/or antiredeposition. The pendant hydrophobic side chains preferably comprise alkyl chains containing from 4 to 20 carbon atoms and may be linked to the backbone via an ester linkage.
