Liquid detergent compositions comprising quaternary nitrogen-containing and/or zwitterionic polymeric suds enhancers

A liquid detergent composition having increased suds volume and suds retention suitable for use in hand dishwashing, said compositions comprising:

• a) an effective amount of a quaternary nitrogen-containing monomeric unit or zwitterionic monomeric unit-containing polymeric suds enhancer, said enhancer comprising:
• i) units selected from the group consisting of units having the formula:
• wherein R1 is a hydrogen or a methyl group;
• R2, R3 and R4 are linear or branched C1-C4 alkyl groups;
• n represents an integer from 1 to 4;
• and X− represents a counterion which is compatible with the water-soluble or water-dispersible nature of the polymer;
• wherein R5, R6, R7 and R8 are independently H, or a C1-C4 alkyl group, k is an integer from 1 to 4;
• and X− represents a counterion which is compatible with the water-soluble or water-dispersible nature of the polymer;
• and
• wherein R9 and R10 are independently H, or a C1-C4 alkyl group;
• and m is an integer from 1 to 4;
• and mixtures thereof;
• provided that said suds enhancer has an average cationic charge density of 2.8 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12;
• b) an effective amount for removing soil and/or grease from the surface of dishware, 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 about 4 to about 12.
