More Information
Summary:The present invention relates to photochemical singlet oxygen generators useful as bleaching agents for laundry detergent compositions or in hard surface cleaning compositions and as anti-microbials. The photochemical singlet oxygen generators comprise a heavy atom unit-containing axial unit wherein the heavy atoms overlap with the pi electron cloud of the photosensitizer unit and enhance the quantum efficiency of the transition of an electron from exited singlet state to triplet state.
