Abstract

The present invention relates to a dye transfer inhibiting detergent composition comprising

a) 0.0001% to 10% by weight of a dye transfer inhibitor having a ratio of amine to amine N-oxide of from about 2:3 to about 1:1,000,000 selected from the group consisting of poly(2-vinylpyridine-N-oxide), poly-2-(dimethylamino)-ethylmethacrylate-N-oxide and poly-1-vinylimidazole-N-oxide; and

b) a detersive effective amount of a surfactant; and

c) a detersive effective amount of a builder.

Claims

1. A dye transfer inhibiting detergent composition comprising

a) 0.0001% to 10% by weight of a dye transfer inhibitor having a ratio of amine to amine N-oxide of from about 2:

3 to about 1;

1,000,000 selected from the group consisting of poly(2-vinylpyridine-N-oxide), poly-2-(dimethylamino)-ethylmethacrylate-N-oxide and poly-1-vinylimidazole-N-oxide; and

b) a detersive effective amount of a surfactant; and

c) a detersive effective amount of a builder.

2. A dye transfer inhibiting detergent composition according to claim 1 in the form of a non-dusting granule or a liquid.

3. A dye transfer inhibiting detergent composition according to claim 1 which additionally comprises enzymes, chelants, bleaching agents, soil-suspending agents, suds suppressors, soil release agents, optical brighteners, abrasives, bactericides, tarnish inhibitors, coloring agents, perfumes or mixtures thereof.
