Abstract
The need for a liquid hand-dishwashing composition which provides further improved sudsing volume and longevity when washing dishware, especially at elevated temperatures, using diluted liquid hand dishwashing compositions, and especially in the presence of greasy soil and particulate soil, while avoiding unsightly residues on dishware, is met by combining a sudsing surfactant system with an EO-PO-EO triblock copolymer and a highly ethoxylated nonionic surfactant.
Claims20
A liquid hand dishwashing cleaning composition comprising:
- a. from about 5% to about 50% by weight of the total composition of a surfactant system, wherein the surfactant system comprises from about 0.1% to about 10% by weight of the total composition of an alkyl ethoxylated nonionic surfactant of formula:
- R1(PO)n(EO)mOH (II)
- wherein:
- R1 is a C8 to C19 alkyl chain;
- m is a number average of from 13 to about 50, and n is a number average of from 1 to about 6, wherein in the alkyl ethoxylated nonionic surfactant of formula (II), R1 is branched and selected from the group consisting of:
- i. R1 is
- wherein
- R2 is a C4 to C9 alkyl chain;
- R3 is a C2 to C7 alkyl chain;
- with the proviso that R2 comprises 2 more carbon atoms than R3;
- ii. R1 is
- wherein:
- R4 is a C4 to C11 alkyl chain;
- R5 is a C3 to C7 alkyl chain;
- and
- iii. mixtures thereof;
- and
- b. from about 0.1% to about 5.0% by weight of the total composition of at least one ethyleneoxide (EO)— propyleneoxide (PO)— ethyleneoxide (EO) triblock co-polymer of Formula (I):
- (EO)x-(PO)y-(EO)x (I)
- wherein:
- each x is independently a number average between about 3 and about 50;
- and
- y is a number average between 5 and 60.

- wherein
- R2 is a C4 to C9 alkyl chain;
- R3 is a C2 to C7 alkyl chain;
- with the proviso that R2 comprises 2 more carbon atoms than R3;
- ii. R1 is
- wherein:
- R4 is a C4 to C11 alkyl chain;
- R5 is a C3 to C7 alkyl chain;
- and
- iii. mixtures thereof;
- and
- b. from about 0.1% to about 5.0% by weight of the total composition of at least one ethyleneoxide (EO)-propyleneoxide (PO)-ethyleneoxide (EO) triblock co-polymer of Formula (I):
- (EO)x-(PO)y-(EO)x (I)
- wherein:
- each x is independently a number average between about 3 and about 50;
- and
- y is a number average between 5 and 60.
