Bleaching with improved whitening

摘要: The invention provides methods, compositions and kits for increasing the brightness retention of a fabric laundered using hypohalite-generating bleach by employing an amount bromide-releasing compound sufficient to provide between 0.1 about 1.5 moles bromine ion mole available chlorine in wash liquor mitigate negative effects said hypohalite on optical brightener present either or fabric. also applies fabrics washed commercial laundry detergents which typically deliver into liquor, generally exhibiting instability presence bleaches. By inventive methods and/or use compositions, enhanced protection is enabled, resulting increased brightening fabrics, determined versus control as increase Stensby whiteness measure ΔW value greater than 3.0.
