PROBLEM TO BE SOLVED: To obtain the subject granule excellent in solubility, useful as a bleaching agent to be used for bleaching clothing, etc., a bleaching detergent, especially a high bulk density bleaching detergent, by compacting a specific bleaching activator mixture and a water-soluble binder at a specific temperature, grinding and granulating into specific particle diameters. SOLUTION: (A) A bleaching activator mixture as a mixture of two or more selected from a compound of formula I [R1 is a >=7C alkyl or alkenyl; X1 is a group of the formula SO3 M1 (M1 is H, an organic or inorganic salt-forming cation) or a group of the formula COOM2 (M2 is M1 ), a compound of formula II (R2 is R1 ; X2 is X1 ) and a of formula III (R3 is R2 ; X3 is X1 ) and (B) a water- soluble binder are compacted at a temperature equal to or higher than the melting point of the component B. The compacted material is ground by impact and shear force by a high-revolution knife cutter and granulated into an average particle diameter larger than 300μm. |
