Automatic dishwashing compositions containing water soluble cationic or amphoteric polymers

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;
• and
• b) 1 to 90 wt. % of a builder selected from the group consisting of a phosphate builder, a non-phosphate builder and mixtures thereof.
