Abstract

The purpose of the present invention is to provide a hypochlorous acid aqueous solution having excellent antimicrobial effect and safety. An antimicrobial agent is provided which is a hypochlorous acid aqueous solution with a pH of 3.0-6.7, wherein the effective chlorine concentration in the aqueous solution is 50-260 ppm. Further, a sterilization method is provided characterized by immersing the member to undergo sterilization treatment in the aforementioned antimicrobial agent for 0.5-10 minutes. The antimicrobial agent has a broad antimicrobial spectrum of noroviruses, Staphylococcus aureus and other bacteria, yeast belonging to Rhodotorula, and Cladosporium cladosporioides and other fungi.

Abstract

Provided is an aqueous hypochlorous acid solution that has an excellent bactericidal effect and high safety. In the aqueous hypochlorous acid solution according to the present invention that has a pH value within the range of 5.5-6.5, starting materials are dissolved exclusively in purified water specified by Japanese Pharmacopeia. The starting materials are sodium hypochlorite for food additives and dilute hydrochloric acid specified by Japanese Pharmacopeia. The pH value of the aqueous hypochlorous acid solution is preferably 6.3.
