The present invention relates to liquid laundry detergent compositions which provide enhance hydrophilic soil cleaning benefits, said compositions comprising: a) from about 0.01 to about 20 % by weight, of a zwitterionic polymer which comprises a polyamine backbone, said backbone comprising two or more amino units wherein at least one of said amino units is quaternized end wherein at least one amino unit is substituted by one or more moieties capable of having an anionic charge wherein further the number of amino unit substitutions which comprise an anionic moiety is less than or equal to the number of quaternized backbone amino units; b) from about 0.1 % to about 7 % by weight, of a polyamine dispersant; c) from about 0.01% to about 80 % by weight, of a surfactant system comprising one or more surfactants selected from the group consisting of nonionic, anionic, cationic, zwitterionic, ampholytic surfactants, and mixtures thereof; and d) the balance carriers and adjunct ingredients.
L'invention porte sur un détergent liquide pour lessives à pouvoir amélioré d'élimination des salissures hydrophiles comprenant: a) d'environ 0,01 à environ 20 % en poids, d'un polymère zwittérionique, dont le squelette, de polyamine, comporte au moins deux unités amino dont l'une au moins est quaternisée, et dont l'une au moins est substituée par un ou plusieurs fragments pouvant présenter une charge anionique, et où de plus le nombre de substitutions d'unités amino comportant un fragment anionique est inférieur ou égal à celui des unité amino quaternisées du squelette. b) d'environ 0,1 % à environ 7 % en poids, d'un dispersant de polyamine; c) d'environ 0,1 % à environ 80 % en poids d'un système de tensio-actifs, comprenant un ou plusieurs tensio-actifs choisis parmi des tensio-actifs non ioniques, anioniques, cationiques, zwittérioniques, ampholytiques ou leur mélange; et d) le reliquat d'entraîneurs et d'additifs.
