Abstract: PROBLEM TO BE SOLVED: To provide a bleaching agent-contg. detergent compsn. excellent in bleaching effect by compounding a percarbonate or perborate (A), an amidoamine oxide surfactant (A), and an alkali agent (C). SOLUTION: Ingredient A having an effective oxygen concn. of 8-16wt.% is used, sodium percarbonate being esp. pref. in terms of bleaching effect. Ingredient B is represented by formula I (wherein R1 is a 7-19C alkyl or alkenyl; R2 is H, a 1-5C alkyl, alkenyl, or hydroxyalkyl; R3 and R4 are each a 1-3C alkyl or alkenyl; and n is 1-5). In formula I, R1 is pref. a 9-15C alkyl; n is pref. 3; R2 is pref. H or methyl; and R3 and R4 are each pref. methyl or ethyl. Examples or ingredient C are an inorg. alkali metal salt (e.g. a crystalline silicate) and a polyphosphate. Further addition of a bleaching activator is pref. in order to enhance the bleacing effect of ingredient A. The compounding ratio of A:B:C is (2-50wt.%):(3wt.% or higher):(3-50wt.%). The total amt. of surfactants including ingredient B is 10-50wt.%.
