| Abstract |
A bleaching composition comprising: ( i) from about 1 to about 60% by weight of a peroxygen compound; ( ii) from about 0.05 to about 10% of an oxygen transfer agent whose structure is: J R1R2C=NS02R3 wherein: R1 may be a substituted or unsubstituted radical selected from the grouping consisting of hydrogen, phenyl, aryl, heterocyclic ring, alkyl and cycloalkyfej radicals; "*"**- R2 may be a substituted or unsubstituted radical selected from the group consisting of hydrogen, phenyl, aryl, heterocyclic alkyl, cycloalkyl, R1C=NS02R3, nitro, halo, cyano, alkoxy, keto, carboxylic, and carboalkoxy radicals; R3 may be a substituted or unsubstituted radical selected from the group consisting of phenyl, aryl, heterocyclic ring, alkyl, cycloalkyl, nitro, halo and cyano radicals; R1 with R2 and R2 with R3 may respectively together form a cycloalkyl, heterocyclic, and aromatic ring system; and (iii) from about 0.1 to about 40% of a bleach precursor that reacts with peroxide anion and forms therewith a peracid or perimidic acid. |
