Patent ID: 7169745

Claim:
A hand dishwashing composition comprising: (a) a polymeric suds stabilizer selected from the group consisting of: (i) a polymer comprising at least one monomeric unit having the formula: wherein each of R 1 , R 2 and R 3 are independently selected from the group consisting of hydrogen, C 1 to C 6 alkyl, and mixtures thereof; L is O; Z is CH 2 ; z is an integer selected from about 2 to about 12; A is NR 4 R 5 , wherein each of R 4 and R 5 are independently selected from the group consisting of hydrogen, C 1 to C 8 alkyl, and mixtures thereof, or NR 4 R 5 form an heterocyclic ring containing from 4 to 7 carbon atoms, optionally containing additional hetero atoms, optionally fused to a benzene ring, and optionally substituted by C 1 to C 8 hydrocarbyl; (ii) a proteinaceous suds stabilizer having an isoelectric point form about 7 to about 11.5; (iii) a zwitterionic polymeric suds stabilizer; and (iv) mixtures thereof; and wherein said polymeric suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons; (b) a detersive surfactant; (c) an amine oxide; and (d) carriers and optionally, other adjunct ingredients, with the proviso that the hand dishwashing composition does not contain builders.
