Abstract
A stable liquid detergent composition having a pH comprised between 7.5 and 8.4 and comprising an alkyl ethoxy sulfate surfactant, an amine oxide surfactant and a polyethyleneimine polymer to provide improved grease cleaning and sudsing and to reduce solution slipperiness.
Claims14
A liquid detergent composition having a pH 10% dilution comprised between about 7.5 and about 8.4, preferably between about 7.7 and about 8.0, and comprising:
- a) from about 0.01% to about 10% by weight of the composition of an alkoxylated polyethyleneimine polymer comprising a polyethyleneimine backbone having from about 400 to about 10000 weight average molecular weight and the alkoxylated polyethyleneimine polymer further comprises:
- (1) one or two alkoxylation modifications per nitrogen atom by a polyalkoxylene chain having an average of about 1 to about 30 alkoxy moieties per modification, wherein the terminal alkoxy moiety of the alkoxylation modification is capped with hydrogen, a C1-C4 alkyl or mixtures thereof,
- (2) a substitution of one C1-C4 alkyl moiety and one or two alkoxylation modifications per nitrogen atom by a polyalkoxylene chain having an average of about 1 to about 40 alkoxy moieties per modification wherein the terminal alkoxy moiety is capped with hydrogen, a C1-C4 alkyl or mixtures thereof;
- or
- (3) a combination thereof:
- b) from about 0.1% to about 15% by weight of the composition of an amine oxide surfactant:
- and
- c) from about 5% to about 40% by weight of the composition of an alkyl sulfate surfactant selected from the group consisting of at least an alkyl ethoxylated sulfate surfactant, potentially an alkyl sulfate surfactant, and mixtures thereof;
- wherein the overall average ethoxylation degree for these alkyl sulfate surfactants is below or equal to 2.
