Patent ID: 7214650

Claim:
A composition for manually cleaning an object, said composition comprising a hand laundry composition, a personal cleansing composition, or a shampoo, in which suds produced by the composition in an aqueous washing solution is maintained for an extended period of time by a polymeric suds stabilizer, said suds stabilizer being selected from the group consisting of: (a) polymers comprising at least one monomeric unit of 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 selected from the group consisting of O, NR 6 , SR 7 R 8 and mixtures thereof, wherein R 6 is selected from the group consisting of hydrogen, C 1 to C 8 alkyl and mixtures thereof; each of R 7 and R 8 are independently hydrogen, O, C 1 to C 8 alkyl and mixtures thereof, or SR 7 R 8 form a heterocyclic ring containing from 4 to 7 carbon atoms, optionally containing additional hetero atoms and optionally substituted; Z is selected from the group consisting of: —(CH 2 )—, (CH 2 —CH═CH)—, —(CH 2 —CHOH)—, (CH 2 —CHNR 6 )—, —(CH 2 —CHR 14 —O—)— and mixtures thereof; wherein R 14 is selected from the group consisting of hydrogen, C, to C 6 alkyl and mixtures thereof; z is an integer selected from 0 to 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; and wherein said polymeric suds stabilizer has a molecular weight of from 1,000 to 2,000,000 daltons; (b) a proteinaceous suds stabilizer, said proteinaceous suds stabilizer having an isoelectric point of from 7.5 to 11.5; (c) a zwitterionic polymeric suds stabilizer; and (d) mixtures thereof; wherein said composition further comprises an organic diamine having a molecular weight less than or equal to 400 g/mol.
