Abstract
The present invention relates to a hand dishwashing cleaning composition including a surfactant system, wherein the surfactant system includes an anionic surfactant and a co-surfactant, wherein the anionic surfactant includes a mixture of a linear anionic surfactant and a branched anionic surfactant with a defined degree of branching on an alkyl ethoxy sulfate surfactant. Such compositions exhibit surprising and unexpected improved sudsing profile, preferably stable suds, especially when the manual dishwashing is performed in a sink full of water with the cleaning composition diluted in it.
Claims19
A liquid hand dishwashing cleaning composition comprising:
- A) from about 1% to about 60% by weight of the total composition of a surfactant system comprising an anionic surfactant and a co-surfactant, wherein:
- i) the average alkyl chain length of the anionic surfactant is from about 8 to about 18 carbon atoms;
- ii) the anionic surfactant has a weight average degree of branching of from about 27% to about 34%, and an average degree of ethoxylation of less than about 5;
- iii) at least one anionic surfactant consists of a mixture of linear alkyl sulfate, branched alkyl sulfate, linear alkyl ethoxy sulfate, and branched alkyl ethoxy sulfate, wherein from about 5% to about 45% by weight of the branched alkyl sulfate and branched alkyl ethoxy sulfate is branched alkyl ethoxy sulfate and from about 55% to about 95% by weight of the branched alkyl sulfate and branched alkyl ethoxy sulfate is branched alkyl sulfate;
- and
- iv) at least one co-surfactant has the formula R1-N(R2)(R3)O wherein R1 is a C8-18 alkyl and R2 and R3 are selected from the group consisting of methyl, ethyl, propyl, isopropyl, 2-hydroxethyl, 2-hydroxypropyl and 3-hydroxypropyl, wherein at least one co-surfactant is present in an amount from 10% to 40% by weight of the surfactant system;
- wherein the weight ratio of the anionic surfactant to the co-surfactant is from about 1:1 to about 8:1.
A hand dishwashing cleaning composition comprising:
- A) from about 15% to about 40% by weight of the total composition of a surfactant system comprising an anionic surfactant, and an amine oxide co-surfactant, wherein:
- i) the anionic surfactant has a weight average degree of branching of from about 29% to about 32% and an average degree of ethoxylation of between about 0.5 and about 0.9;
- ii) the anionic surfactant and amine oxide co-surfactant are in weight ratio of between about 2.5:1 and about 4:1;
- iii) at least one anionic surfactant consists of a mixture of linear alkyl sulfate, branched alkyl sulfate, linear alkyl ethoxy sulfate, and branched alkyl ethoxy sulfate, wherein
- from about 5% to about 30% by weight of the branched alkyl sulfate and branched alkyl ethoxy sulfate is branched alkyl ethoxy sulfate and from about 70% to about 95% by weight of the branched alkyl sulfate and branched alkyl ethoxy sulfate is branched alkyl sulfate;
- and
- iv) the amine oxide co-surfactant has the formula R1-N(R2)(R3)O wherein R1 is a C8-18 alkyl and R2 and R3 are selected from the group consisting of methyl, ethyl, propyl, isopropyl, 2-hydroxethyl, 2-hydroxypropyl and 3-hydroxypropyl, wherein the amine oxide surfactant is present in an amount from 10% to 40% by weight of the surfactant system.
