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 block polymeric suds stabilizer, said stabilizer comprising: i) one or more cationic group-containing units; and ii) optionally, one or more additional building block units; b) an effective amount of a detersive surfactant; c) a diamine having molecular weight less than or equal to 400 g/mol; and d) 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; said suds stabilizer comprises a cationic 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 mixtures thereof; T is an ester group; Z is selected from the group consisting of: â€”(CH2)â€”, (CH2â€”CH&boxH;CH)â€”, â€”(CH2â€”CHOH)â€”, (CH2â€”CHNR6)â€”, â€”(CH2â€”CHR14â€”O)â€” and mixtures thereof; wherein R14 is selected from the group consisting of hydrogen, C1 to C6 alkyl, 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, alkyleneoxy having the formula: â€”(R10O)yR11 â€ƒwherein R10 is C2-C4 linear or branched alkylene, and mixtures thereof; R11 is hydrogen, C1-C4 alkyl, and mixtures thereof; y is from 1 to about 10.
