Abstract
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 and 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.
