Abstract:
A bleaching formulation comprising the components of:(a) a peroxy bleaching agent selected from the group consisting of hydrogen peroxide, organic peroxide and an organic peracid, wherein the organic peroxide and the organic peracid are capable of generating hydrogen peroxide in an aqueous solution; (b) an anionic bleaching activator comprising a metal; and (c) a cationic compound that is an amino compound salt or a quaternized amino compound salt; with the proviso that component (b) is a complex selected from the group consisting of formulae (I), (III) and (IV): wherein R1 represents one of a straight-chain alkylene or alkenylene group having 2 to 8 carbon atoms, a cycloalkylene or cycloalkenylene group having 3 to 8 carbon atoms or a phenylene group; R2, R3 and R4 each independently represent one of a methylene group, a straight-chain alkylene or alkenylene group having 2 to 8 carbon atoms, a cycloalkylene or cycloalkenylene group having 3 to 8 carbon atoms or a phenylene group; R1, R2, R3 and R4 may each have a substituent(s) which is an alkyl, alkenyl, alkynyl, alkoxy or halogenated alkyl group having up to 8 carbon atoms, a cycloalkyl or cycloalkenyl group having 3 to 8 carbon atoms, an aryl group, an aryl group having a straight-chain alkyl group having 1 to 18 carbon atoms, a hydroxyl group, a phenoxy group, a halogen atom, an amino group, a sulfuric acid radical, a sulfo group, a nitro group, or a carboxyl group; M represents a metal which is a transition metal having a I, II, III, IV, V, VI, VII or VIII-valent oxidized state; and X represents a counter ion in equilibrium with the compound's charges on a stoichiometric basis.
