Liquid detergent composition

A method of cleaning a dishware with a liquid detergent composition comprising an amphiphilic graft polymer;

• said method comprising the steps of contacting said composition with said dishware, wherein said polymer is a random graft copolymer having a hydrophilic backbone comprising monomers selected from the group consisting of ethers, alcohols, aldehydes, ketones or esters, sugar units, alkoxy units, saturated polyalcohols, and mixtures thereof, and hydrophobic side chains selected from the group consisting of a C4-25 alkyl group, polypropylene, polybutylene, and a mixture thereof;
• wherein the graft polymer is further characterized by being based on water-soluble polyalkylene oxides comprising alkylene oxide units (A) as backbone and side chains formed by polymerization of a vinyl ester component (B), said polymer having no more than about 0.4 graft site per 50 alkylene oxide units and mean molar masses Mw of from about 3,000 to about 100,000, said polymer having a polydispersity Mw/Mn of from about 1.5 to about 2.2;
• wherein the graft polymer has
• (A) from about 20% to about 70% by weight of the water-soluble polyalkylene oxide as a backbone, wherein the polyalkylene oxide is capped at least at one end by a C1-C25 alkyl group having a mean molar mass Mn from 1500 to 20,000;
• (B) side chains formed by free-radical polymerization in the presence of (A) of from about 30% to about 80% by weight of a vinyl ester component composed of
• (B1) from about 90% to about 100% by weight of vinyl acetate and
• (B2) from 0 to about 30% by weight of a further ethylenically unsaturated monomer in the presence of (A),
• wherein the alkylene oxide units (A) comprise from about 95% to about 100% of ethylene oxide,
• wherein the composition further comprises a polymeric suds stabilizer selected from the group consisting of homopolymers of (N,N-dialkylamino) alkyl esters, (N,N-dialkylamino) alkyl acrylate esters, and mixtures thereof.
