A laundry detergent composition comprising an amphiphilic graft polymer based on water- soluble polyalkylene oxides as a graft base and side chains formed by polymerization of a vinyl ester component, said polymer having an average of less than or equal to one graft site per 50 alkylene oxide units and a mean molar mass of from about 3,000 to about 100,000; from about 0.2% to about 8% of organic solvent; and from about 2% to about 20% of a surfactant system; wherein said detergent composition is in a form selected from: liquid; gel; and combinations thereof.

Cette invention concerne une composition de détergent de lessive comprenant un polymère greffé amphiphile à base d'oxydes de polyalkylène hydrosoluble en tant que base de greffe et des chaînes latérales formées par polymérisation d'un composant ester vinylique. Le polymère présente une moyenne égale ou inférieure à un site de greffe par 50 unités d'oxyde d'alkylène et une masse molaire moyenne comprise entre environ 3000 et environ 100000; de 0,2% environ à 8% environ d'un solvant organique; et de 2% environ à 20% environ d'un système tensioactif; la composition de détergent susmentionnée se présente sous la forme d'un liquide, d'un gel, ou une combinaison des deux.
