PROBLEM TO BE SOLVED: To provide a method for producing a disinfectant antiseptic solution which, by diluting an aqueous solution of a chlorine agent, which is sodium hypochlorite, with carbonic water and thereafter performing a pH adjustment with an acid substance, for example, a dilute aqueous hydrochloric acid solution, has a pH stabilization effect for carbon dioxide by a carbonic acid aqueous solution, and exerts no influence on the object to be sterilized and the pH of a diluted solution even when, the solution is diluted, for example, with city water.SOLUTION: An aqueous solution of a chlorine agent, for example, an aqueous solution of sodium hypochlorite is diluted with carbonic water or carbon dioxide, and, thereafter, pH adjustment is performed by dissolving an acid substance such as a dilute aqueous hydrochloric acid solution.COPYRIGHT: (C)2014,JPO&INPIT【課題】次亜塩素酸ナトリウムである塩素剤水溶液に、炭酸水で希釈した後に、酸性物質、実施例において希塩酸水溶液でpH調整を行うようにしたことで、炭酸水溶液による二酸化炭素にpH安定効果があり、殺菌する対象や希釈液、例えば水道水で希釈したときでもpHに影響を与えない殺菌消毒液の製造方法を提供する。【解決手段】塩素剤水溶液、例えば、次亜塩素酸ナトリウム水溶液を炭酸水或は炭酸ガスで希釈した後に、酸性物質、例えば希塩酸水溶液を溶解することによりpH調整を行うようにする。【選択図】図1
