Title:

Photochemical superoxide generators

Document Type and Number:

WIPO Patent Application WO1998032829

Kind Code:

A3

Abstract:

Disclosed are photochemical super oxide generators useful as photobleaches for laundry detergent compositions and as photobleaches or photodisinfectants for use in hard surface cleaning compositions. The compounds described herein comprise an amino-containing electron transfer moiety bonded to the photosensitizing unit wherein the amino-containing moiety is capable of transferring an electron to the photochemically excited pi electron cloud of the photosensitizer unit thereby enabling superoxide formation.
