Abstract

A pretreater or laundry additive composition which removes stains and as a laundry additive, whiten fabrics are described herein. The compositions contain 0.1 to 20 wt. % of a nonionic surfactant, 0.1% to 10 wt. % of a hydrophobically modified polymer and less than about 5 wt. % of an anionic soap. Methods of using the composition are also described.
