Laundry detergent composition comprising substantially water-insoluble polymeric dye transfer inhibiting agent
First Claim
1. A laundry detergent composition comprising:
- a) 0.01% to 3% by weight, of a substantially water-insoluble polymeric dye transfer inhibiting agent, said agent consisting of a substantially water-insoluble cross linked polymer selected from the group consisting of polyamine N-oxide polymers;
copolymers of N-vinylpyrrolidone and N-vinylimidazole;
polyvinylpyrrolidones;
polyvinyloxazolidones;
polyvinylimidazoles; and
mixtures thereof;
wherein said agents have a particle size less than 50 microns;
b) from 0.2% to 25% by weight of a surfactant system, said surfactant system comprising one or more detersive surfactants selected from the group consisting of anionic, nonionic, cationic, zwitterionic, ampholytic surfactants, and mixtures thereof; and
c) the balance carriers and adjunct ingredients.

Abstract
The present invention relates to laundry detergent compositions which are suitable for use in inhibiting the re-deposition of fugitive dyes onto fabric during the course of the laundry process, said compositions comprising:
a) 0.01% to 3% by weight, of a substantially water-insoluble polymeric dye transfer inhibiting agent, said agent consisting of a substantially water-insoluble cross linked polymer selected from the group consisting of polyamine N-oxide polymers; copolymers of N-vinylpyrrolidone and N-vinylimidazole; polyvinylpyrrolidones; polyvinyloxazolidones; polyvinylimidazoles; and mixtures thereof; wherein said agents have a particle size less than 50 microns;
b) from 0.2% to 25% by weight of a surfactant system, said surfactant system comprising one or more detersive surfactants selected from the group consisting of anionic, nonionic, cationic, zwitterionic, ampholytic surfactants, and mixtures thereof; and
c) the balance carriers and adjunct ingredients.
The compositions of the present invention are also compatible with peroxygen, as well as, hypochlorite bleaching systems.
