Abstract:
A dishwashing detergent composition comprising:a) a cleaning effective amount of a water-soluble cationic or amphoteric polymer; wherein the cationic polymer comprises at least 1 or more polymerized monomer units selected from the group consisting of a) ethylenically unsaturated compounds selected from the group consisting of co-poly 2-vinyl pyridine and co-poly 2-vinyl N-alkyl quaternary pyrridinium salt derivatives, co-poly 4-vinyl pyridine and co-poly 4-vinyl N-alkyl quaternary pyridinium salt derivatives, co-poly 4-vinyl benzyltrialkylammonium salts, co-poly 2-vinyl piperidine and co-poly 2-vinyl piperidinium salt; co-poly 4-vinylpiperidine and co-poly 4-vinyl piperidinium salt; co-poly 3-alkyl 1-vinyl imidazolium salts, b) from the group consisting of co-poly vinyl amine and co-polyvinylammonium salt, co-poly diallylamine, co-poly methyldiallylamine, and co-poly diallydimethylammonium salt or c) from the ionene class of internal cationic monomers;and, wherein the amphoteric polymer comprises at least one cationic monomer as defined above and at least one monomer unit having an anionic charge; andb) 1 to 90 wt. % of a builder selected from the group consisting of a phosphate builder, a non-phosphate builder and mixtures thereof.
