ABSTRACT:
Disclosed are detergent compositions and methods which are suitable for washing colored fabrics in aqueous washing solution with little or no transfer of dye between fabrics. The compositions utilized comprise certain nil-LAS detersive surfactants, detergent builder and certain selected polymeric dye transfer inhibiting agents. The detersive surfactants used must comprise alkyl ether sulfates and certain types of nonionic surfactants (polyhydroxy fatty acid amides and/or alcohol ethoxylates). The polymeric dye transfer inhibiting agents are polyamine N-oxides such as poly(4-vinylpyridine-N-oxide), i.e., PVNO and/or copolymers of N-vinylpyrrolidone and N-vinylimidazole, i.e., PVPVI.
