Abstract:
A liquid detergent composition having increased suds volume and suds retention suitable for use in hand dishwashing, said composition 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 about 4 to about 12; â€ƒprovided that said suds stabilizer has an average cationic charge density from about 0.05 to about 5 units per 100 daltons molecular weight at a pH of from about 4 to about 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 about 4 to about 12. wherein said polymeric suds stabilizer (a) is a homopolymer comprising at least one monomeric unit of the formula: wherein each of R1, R2 and R3 are independently selected from the group consisting of hydrogen, C1 to C6 alkyl, and mitures thereof; L is O; Z is selected from the group consisting of: â€”(CH2)â€”, (CH2â€”CH&boxH;CH)â€”, â€”(CH2â€”CHOH)â€” and mixtures thereof; z is an integer selected from about 0 to about 12; A is NR4R5, wherein each of R4 and R5 are independently selected from the group consisting of hydrogen, C1-C8 linear or branched alkyl and mixtures thereof; and wherein said polymeric suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons.
