Claim 0:
1. An automatic dishwashing detergent composition comprising:
a) from about 0.5 wt % to about 5 wt % of a quaternized alkoxylated polyalkyleneimine comprising a polyalkyleneimine backbone, alkoxy chains and quaternization groups wherein the quaternized alkoxylated polyalkyleneimine has a degree of quaternization of from about 40% to about 98% and wherein:
i) the polyalkyleneimine backbone represents from about 1% to about 40% by weight of the quaternized alkoxylated polyalkyleneimine;
ii) the alkoxy chains represent from about 60% to about 99% by weight of the quaternized alkoxylated polyalkyleneimine, and wherein the alkoxy chains are selected from polyoxyethylene chains having an average of from about 1 to about 50 ethoxy units, polyoxypropylene chains having an average of from about 0 to about 30 propoxy units and mixtures thereof, and wherein said polyalkyleneimine backbone has a weight-average molecular weight of 600 to 5000 g/mol;

b) from about 5 wt % to about 25 wt % of percarbonate bleach;
c) from about 0.05 to about 10 mg of active amylase/g of the composition and from about 0.05 to about 20 mg of active protease/g of the composition; and
wherein the composition is free of bleach activator and bleach catalyst, or wherein the composition is free of bleach activator and comprises manganese bleach catalyst.
