PURPOSE: To obtain the subject composition showing excellent bleaching effect on blood stain, containing a specific potassium alkylbenzenesulfonate, sodium percarbonate and an organic peracid precursor in a specific ratio. CONSTITUTION: This composition contains (A) 2-30wt.% of a 10-16C alkyl chain- containing potassium alkylbenzenesulfonate, (B) 0.5-30wt.% of sodium percarbonate coated with boric acid (salt), (C) 0.1-10wt.% of an organic acid precursor of the formula [R is a 1-21C alkyl or alkenyl or (alkyl-substituted) aryl; M is H, an organic or inorganic cation] (e.g. sodium 2- octanoyloxybenzoate), preferably further (D) 2-30wt.% of potassiumα- olefinsulfonate containing a 12-22C alkyl or alkenyl, (E) 1-50wt.% of a crystalline alkali metal silicate, (E) 1-50wt.% of a crystalline alkali metal silicate and (F) 1-50wt.% of an aluminosilicate.
