The need for liquid hand dishwashing cleaning compositions that comprise alkyl sulfate anionic surfactant having little or no ethoxylation, which provides improved low temperature stability while also achieving the desired product viscosity, suds mileage and overall cleaning is met by formulating the liquid hand dishwashing detergent composition to comprise branched alkyl sulfate anionic surfactant having a high level of non-C2-branching, especially with a specific alkyl branching distribution, and an average degree of alkoxylation of less than 0.5.

Liquid hand dishwashing cleaning composition

The need for a liquid detergent composition comprising alkyl sulfate anionic surfactant which comprises little or no alkoxylation which provides a Newtonian viscosity profile over a larger shear rate range, and where the composition viscosity is less affected by changes in temperature, is met by formulating the liquid hand dishwashing detergent composition that comprises branched alkyl sulphate anionic surfactant with an average degree of alkoxylation of less than 0.5 and with the specific alkyl branching distribution as described herein, in combination with a co-surfactant selected from the group consisting of an amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof, in the weight ratio of the anionic surfactant to the co-surfactant of from 2.0:1 to 8.0:1.

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 surfactant system, the surfactant system comprising an alkyl sulfate anionic surfactant comprising little or no branching and 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.

The need for a hand-dishwashing composition which is highly effective at removing grease, providing long-lasting suds under soiled conditions, while having a Newtonian viscosity which is less sensitive to changes on surfactant and solvent levels, is met by formulating the liquid hand dishwashing cleaning composition to comprise a surfactant system having a combination of alkyl sulphate anionic surfactant having little or no alkoxylation and an alkyl polyglucoside surfactant.

Liquid hand dishwashing cleaning composition with reduced viscosensitivity

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.
