ABSTRACT:
Improved fabric bleaching and stain removal are achieved by use of a composition comprising a photoactivator and a cationic substance. The photoactivator is a porphine or a mono-, di-, tri-, or tetra-aza porphine, solubilized with anionic, nonionic and/or cationic substitutent groups, and metal free or metallated with Zn(II), Ca(II), Cd(II), Mg(II), Sc(III), Al(III) or Sn(IV). The cationic substance is preferably one that, in a laundry bath, itself performs a desired function such as acting as fabric softener, electrostatic control agent, surfactant, or germicide.
