Abstract

Laundry additive compositions and methods for their use are provided. The compositions include a dispersible polyolefin, preferably polyethylene, and at least one compound selected from the group consisting of dye fixative agents, chelating agents, dye transfer inhibiting agents, chlorine scavenging agents, free radical scavenging agents, cellulase enzymes and mixtures thereof. Preferably, the composition is a liquid composition added to the rinse cycle of a consumer laundry process or to a pre-treatment cycle before a wash cycle of a consumer laundry process.
