The present invention relates to compositions comprising photosenitizer that can be used to provide lipophilic fluids with bleaching capabilities, lipophilic fluid cleaning compositions having bleaching capabilities and processes of making and using same. Such compositions provide the cleaning benefits of typical lipophilic solvents and additional cleaning benefits that include bleaching.

Photo bleach lipophilic fluid cleaning compositions

A dishwashing wipe having a nonwaven hydroentangled polymer fiber topsbeet; a polymeric membrane; a nonwoven batting layer; and a polymeric scrim, with a dishwashing composition having an amine, a polymeric suds stabilizer, or enzymes incorporated in the wipe, wherein the dishwashing composition is in the form of stripes on the wipe.

Dishwashing wipe

A disposable dish care and hard surface cleaning wipe is disclosed. In one embodiment, the wipe is comprised of a water insoluble substrate that includes a partially hydrophobic nonwoven first layer, and a low density nonwoven second layer that is adjacent to the said first layer and has melded onto the side facing away from the said first layer an abrasive coating of thermoplastic material nubs or hooks, and a cleaning paste containing a surfactant.

Disposable dish care and hard surface cleaning wipe

Detergent compositions comprising photobleach delivery systems, processes for preparing them, and their methods of use, the compositions combine selected hydrophobic photobleaches, especially based on Si(IV) phthalocyanines, with selected axial ligands, with certain water-soluble polymers, nonbonded ligands, detersuve surfactants, especially certain mid-chain branched types, and non-surfactant detersive adjuncts.

Detergent compositions comprising photobleaching delivery systems

The present invention relates to photochemical singlet oxygen generators having enhanced fabric substantivity, said photochemical singlet oxygen generators useful as photobleaches in laundry detergent compositions. the present invention is also directed to methods for removing stains on fabric by contacting dirty and stained fabric with the photobleaching agents described herein.

Photochemical singlet oxygen generators having cationic substantivity modifiers

The invention relates to photochemical singlet oxygen generators useful as bleaching agents or anti-microbial agents in laundry detergent compositions or in hard surface cleaning compositions. The singlet oxygen generators described herein have enhanced singlet oxygen generation due to aromatic moieties teed to the molecules, said aromatic moieties absorbing ultra violet radiation then re-emitting the radiation as fluorescence at a wavelength absorbable by the singlet oxygen producing photosensitizer unit. The increase in the number of photons having an absorbable wavelength provides an increase in the production of singlet oxygen.

Photochemical singlet oxygen generations having enhanced singlet oxygen yields

Photosensitizing compounds suitable for use as laundry detergent photobleaches are disclosed. The disclosed compounds are phthalocyanine and naphthalocyanines comprising axial moieties selected for their hydrophobic character as measured by their ClogP. Also disclosed are methods for bleaching fabrics and methods for disinfecting hard surfaces.

Photobleaching compositions effective on dingy fabric

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 &pgr; electron cloud of the photosensitizer unit and enhance the quantum efficiency of the transition of an electron from exited singlet state to triplet state.
