PROBLEM TO BE SOLVED: To obtain a bleaching agent composition capable of preventing the hydrolysis of anα-sulfo saturated fatty acid methyl ester salt (α-SF), enabling the simultaneous use of theα-SF excellent as a washing base material with a bleaching base agent, capable of exhibiting the excellent characteristics of both the components. SOLUTION: This high bulk density bleaching detergent comprising a bleaching agent, a bleach-activating agent and detergent particles containing anα-sulfo saturated fatty acid methyl ester salt (α-SF). Therein, (A) 5-25wt.% of theα-sulfo saturated fatty acid methyl ester salt, (B) 3-15wt.% of a fatty acid salt, (C) 1-6wt.% of a nonionic surfactant and (D) >=1wt.% of a sulfite, are contained in a (B)/(A) weight ratio of 1/5 or larger.
