Abstract
The need for a hand-dishwashing composition which is highly effective at removing grease, while also having good suds mileage, and avoiding negatives on physical stability, especially at low temperatures is met by formulating the hand dishwashing composition to comprise a branched alkyl sulfate anionic surfactant having a low degree of alkoxylation, or no alkoxylation, and a co-surfactant, in combination with polypropylene glycol of a defined molecular weight, as described herein.
Claims18
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:
- at least about 40% by weight of the surfactant system of anionic surfactant, wherein the anionic surfactant comprises at least about 50% by weight of the anionic surfactant of alkyl sulfate anionic surfactant, wherein the alkyl sulfate anionic surfactant:
- a. has an alkyl chain comprising an average of from 8 to 18 carbon atoms;
- b. comprises branched alkyl sulfate anionic surfactant such that the alkyl sulfate anionic surfactant has an average degree of branching of at least about 15%, and
- c. has an average degree of alkoxylation of less than about 0.5;
- and
- a co-surfactant selected from the group consisting of an amphoteric surfactant, a zwitterionic surfactant and mixtures thereof;
- and
- b) from about 0.1% to about 10% by weight of the total composition of polypropyleneglycol, wherein the polypropyleneglycol has a weight average molecular weight from about 850 g/mol to about 1000 g/mol.
