Liquid laundry detergent compositions having improved stability and viscosity, and containing from about 5% to about 20%, by weight of the composition, of a surfactant system. The surfactant system contains from about 0.5% to about 15%, by weight of the composition, of a mid-branched primary alkyl sulfate surfactant having an average of from about 14 to about 17 total carbons; at least about 0.1%, by weight of the composition, of an additional surfactant selected from alkyl alkoxy sulfate surfactants, alkyl alkoxy surfactants, and mixtures thereof; and from about 0.1% to about 1.5%, by weight of the composition, of sodium formate. The liquid laundry compositions contain less than about 3% of HLAS surfactants.

L'invention porte sur une composition détergente pour lessive à stabilité et viscosité améliorées, contenant d'environ 5 à environ 20 % en poids de la composition d'un système de tensio-actifs, lequel contient lui-même d'environ 0,5 à environ 15 % en poids de la composition d'un tensio-actif de sulfate d'alkyle primaire ramifié à mi-chaîne à environ une moyenne d'environ 14 à environ 17 CT, au moins environ 0,1 % du poids de la composition d'un tensio-actif additionnel choisi parmi des tensio-actifs de sulfate d'alkyle à liaison alkoxy ou d'alkyl à liaison alkoxy ou leur mélange, et d'environ 0,1 à environ 1,5 % du poids de la composition de formate de sodium. De telles compositions contiennent moins de 3 % de tensio-actifs HLAS.
