Abstract
The present invention relates to liquid detergent compositions comprising a polymeric material which is a suds enhancer and a suds volume extender, said compositions having increased effectiveness for preventing re-deposition of grease during hand washing. The polymeric material which are suitable as suds volume and suds endurance enhancers comprise an effective amount of a polymeric suds stabilizer comprise:i) units capable of having a cationic charge at a pH of from about 4 to about 12;provided that said suds stabilizer has an average cationic charge density from about 0.0005 to about 0.05 units per 100 daltons molecular weight at a pH of from about 4 to about 12.
