ABSTRACT:
This invention provides a process for preventing dye from transferring from one fabric to the same or different fabric in a laundry process. This invention also provides dye transfer inhibiting agents formulated into laundry detergent and fabric softening formulations. More specifically, a process is provided where 1) an aqueous bath is formed comprising a) water, b) dyed fabric, and c) a dye transfer inhibiting agent, 2) the dyed fabric is laundered in the aqueous bath and the fabric releases a portion of the dye from the dyed fabric into the bath, and 3) the dye transfer inhibiting agent is maintained in contact with the dyed fabric for the duration of the laundering step. The laundry detergent and fabric softening formulations are comprised of 0.1 to 15 percent by weight of one or more dye transfer inhibiting agents.
