Abstract
Detergent compositions, essentially free of chlorine bleach compounds, containing a surfactant, builder, enzyme, peroxygen bleach and from about 0.001% to about 5% by weight polyethyleneimine (PEI) or salts thereof are disclosed. These compositions exhibit controlled and improved bleaching action on stains as well as improved storage stability, fabric safety and whitening/brightening characteristics.
