Abstract:
A process for making a free-flowing, particulate dye transfer inhibiting detergent admix for inclusion in a granular laundry detergent composition consisting essentially of the steps of:a) charging from 50% to 95%, by weight of the dye transfer inhibiting detergent admix, of a detergent builder into a mixer/granulator;b) adding to the detergent builder from 5% to 50%, by weight of the dye transfer inhibiting detergent admix, of a dye transfer inhibitor solution to thereby form a mixture wherein the dye transfer inhibitor solution contains a dye transfer inhibitor selected from the group consisting of polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, and mixtures thereof; andc) agglomerating the mixture of the dye transfer inhibitor solution and the detergent builder so as to form the dye transfer inhibiting detergent admix.
