Abstract

PURPOSE: To maintain and enhance the effect as an oxidizing agent, by stabilizing the residual chlorine in an aqueous solution by adding a specific hydantoin compound.
CONSTITUTION: In an aqueous solution containing hypochlorous acid or a salt thereof, a hydantoin compound shown by the formula I or II (wherein R1, R2 are H, 1W4C alkyl or ureido) is added and, by said hydantoin compound, the change of the residual chlorine with the lapse of time is controlled. The amount of the hydantoin compound is pref. about 0.05ppm.
