Abstract
A system for removing extraneous, random free-flowing dyes from laundry washing applications which comprises a novel unitary dosing laundry article that can freely circulate among items being laundered. The laundry article further comprises a dye absorber and a dye transfer inhibitor which are introduced into a wash liquor via a support matrix. The dye absorber maintains a relational association with the support matrix in the wash liquor, whereas the dye transfer inhibitor is delivered up from the support matrix to the wash liquor and may be evenly distributed throughout the wash liquor. The laundry article of the present invention provides a method for preventing the redeposition of extraneous dyes onto other wash items, while simultaneously providing an indicator system for the manifestation of such scavenging process.
