ABSTRACT:
A laundry detergent formulation includes a dirt suspending agent which is a blend of an anionic material, such as an anionic polymer, and a quaternary ammonium salt. This suspending agent prevents redeposition of dirt which is removed from clothing by a laundry detergent from redepositing onto cleaned clothes during the wash cycle, while allowing it to be removed completely during the rinse cycle.
