Abstract
The present invention relates to liquid detergent compositions comprising polymeric suds volume and suds duration enhancers. These polymeric materials provide enhanced suds volume and suds duration during hand washing of dishware, flatware, and pots and pans. The present invention also relates to methods for providing detergent compositions which have enduring suds volume and suds retention when hand washing of said dishware items.
Claims14
A detergent composition suitable for use in hand dishwashing, said composition comprising:
- a) an effective amount of a homopolymeric suds stabilizer containing monomeric units of the formula:
- wherein each of R1, R2 and R3are independently selected from the group consisting of hydrogen, C1 to C6 alkyl, and mixtures thereof;
- L is O Z, is selected from the group consisting of:
- —(CH2)—, (CH2—CH═CH)—, —(CH2—CHOH)— (CH2—CHNR6)—, —(CH2—CHR14—O)— 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 1 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:
- —(R10O)yR11
- wherein 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;
- and wherein said polymeric suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons;
- b) an effective amount of a detersive surfactant;
- and
- c) the balance carriers and other adjunct ingredients;
- provided that the pH of a 10% aqueous solution of said composition is from about 4 to about 12.
A composition according to claim , wherein said polymeric suds stabilizer is a homopolymer of:
A method for providing increased suds volume and increased suds retention while hand washing dishware or cookware articles in need of cleaning, comprising the step of contacting said articles with an aqueous solution of a detergent composition suitable for use in hand disbwashing, said composition comprising:
- a) an effective amount of a homopolymeric suds stabilizer containing monomeric units of the formula:
- wherein each of R1, R2 and R3 are independently selected from the group consisting of hydrogen, C, to C6 alkyl, and mixtures thereof;
- L is O Z is selected from the group consisting of:
- —(CH2)—, (CH2—CH═CH)—, —(CH2—CHOH)—, (CH2—CHNR6)—, —(CH2—CHR14—O)— 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 1 to about 12;
- A is NR4R5, wherein each of R4 and R5 are independently selected from the group consisting of hydrogen, C1 to C8 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;
- b) an effective amount of a detersive surfactant;
- and
- c) the balance carriers and other adjunct ingredients;
- provided that the pH of a 10% aqueous solution of said composition is from about 4 to about 12.
