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;.

Claims

4-1. A composition according to any of claims 1 to 4, wherein said polymeric suds stabilizer (a) is a copolymer of:

12. A method for providing extended suds volume and suds duration when dishware in need of cleaning is washed, comprising the step of contacting said dishware with an aqueous solution of a liquid detergent comprising:

a) an effective amount of a polymeric suds stabilizer, said stabilizer comprising;

i) units capable of having a cationic charge at a pH of from 4 to 12;

provided that said suds stabilizer has an average cationic charge density of at least 0.01 units per 100 daltons molecular weight at a pH of from 4 to 12;

b) an effective amount of a detersive surfactant; and

c) the balance carriers and other adjunct ingredients;

provided that a 10% aqueous solution of said detergent composition has a pH of from 4 to 12.
