THE INEVTNION RELATES TO LIQUID BLEACHING COMPOSITION FOR CATALYTICALLY BLEACHING SUBSTRATES, ESPECIALLY LAUNDRY FABRICS, WITH ATMOSPHERIC OXYGEN OR AIR. A LIQUID BLEACHING COMPOSITION IS PROVIDED COMPRISING AN ORGANIC SUBSTANCE WHICH FORMS A COMPLEX WITH A TRANSITION METAL, THE COMPLEX CATALYSING BLEACHING OF A SUBSTRATE BY ATMOSPHERIC OXYGEN, AND A LIQUID CARRIER OR SOLVENT, WHEREIN THE COMPOSITION IS SUBSTANTIALLY DEVOID OF PEROXYGEN BLEACH OR A PEROXY-BASED OR-GENERATING BLEACH SYSTEM. ALSO PROVIDED IS A METHOD OF BELACHING A SUBSTRATE COMPRISING APPLYING THE LIQUID BLEACHING COMPOSITION TO THE SUBSTRATE. ALSO PROVIDED IS A METHOD OF TREATING A TEXTILE BY CONTACTING THE TEXTILE WITH THE LIQUID BELACHING COMPOSITION, WHEREBY THE COMPLEX CATALYSES BELACHING OF THE TEXTILE BY ATMOSPHERIC OXYGEN AFTER THE TREATMENT. |
