Abstract:
A bleaching detergent formulation comprising the components of:(A) particles comprising 0.01 to 50% by weight, based on the particles, of a compound represented by formula (I): wherein R1 represents 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, which may be the same or different, each represent a methylene group, a straight-chain alkylene or alkenylene group having 2 to 8 carbon atoms, a cycloalkylene group having 3 to 8 carbon atoms or a phenylene group; R1, R2, R3 and R4 may each have a substituent or substituents selected from 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, and a carboxyl group; M represents a metal selected from transition metals 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; and(B) sodium percarbonate particles coated with at least one coating material selected from a polymer, an inorganic salt, and an inorganic acid, and the component (B) has a dissolution rate of 0.05 to 1.5 g/min.
