PROBLEM TO BE SOLVED: To obtain the subject granule excellent in solubility, not fading a colored patterned clothing, etc., useful as a bleaching agent for clothing, etc., a bleaching detergent, especially a high bulk density bleaching detergent, by granulating a specific bleaching activator mixture with a water-soluble binder. SOLUTION: (A) A bleaching activator mixture comprising (A1 ) a compound of formula I [R1 is a 7C alkyl or alkenyl; M1 is H or a cation to provide the bleaching activator with water solubility, such as an alkali metal or a (substituted) ammonium salt] and (A2 ) a compound of formula II (R2 is a 9C alkali or alkenyl; M2 is M1 ) and (A3 ) a compound of formula III (R3 is a 11C alkyl or alkenyl; M3 is M1 ) in the weight ratio of the components A1 /A2 of 0.01-1 and A3 /A2 of 0.01-1 is granulated by (B) a water-soluble binder such as a polyethylene glycol having 300-30,000 average molecular weight or a polyethylene glycol addition type nonionic surfactant having 300-3,000 average molecular weight. |
