PURPOSE:To obtain an acidic bleaching agent capable of suppressing an amount of chlorine gas emitted when combinedly used with a chlorine based bleaching agent, etc., by blending an acidic detergent containing an acidic substance, a surfactant and a water soluble solvent with a hydroxycarboxylic acid (salt) and/or a hydroxytricarboxylic acid (salt). CONSTITUTION:The objective detergent is obtained by blending an acidic detergent containing (A) an acidic substance, preferably containing 1-20wt.% inorganic acid or organic acid except for hydroxydicarboxylic aid and hydroxytricarboxylic acid, having >0.5 pKa, (B) a surfactant and/or (C) a water soluble solvent with (D) a hydroxydicarboxylic acid (salt) and/or a hydroxytricarboxylic acid (salt), preferably in an amount of 120wt.% (based on total amount) as a substance for suppressing an amount of chlorine gas emitted when combinedly used or mixed with a chlorine based bleaching agent or detergent containing a hypochlorous acid salt, etc. |
