ABSTRACT:
A stable, liquid detergent softening and brightening composition or concentrate contains a water-soluble non-ionic surfactant system; a quaternary ammonium softener having an equivalent weight from about 400 to 2000; at least an equivalent weight to said softener of a 4,4'-bis[4-disubstituted amino-6-(sulfosubstituted anilino)-s-triazin-2-ylamino]-2,2'-stilbene disulfonic acid optical brightener; a hydrotrope to stabilize the composition and an aqueous solvent medium therefor. The composition is storage stable and provides enhanced cling-free softening and brightening without loss of cleansing properties or yellowing of fabrics.
