ABSTRACT:
The performance of photobleaches such as the zinc phthalocyanines is enhanced by means of alkylene amino/carboxylate or alkylene amino/phosphonate chelants. Thus, sulfonated zinc phthalocyanine plus diethylenetriamine pentaacetate provide enhanced photobleaching of laundered fabrics. Detergent compositions comprising the improved photobleach systems are provided.
