Problems solved by technology

However, in reality, hypochlorous acid slightly acidic electrolyzed water has complex components and unstable properties. Although there are some reports to enhance stability, such as CN107439588B of Realm Therapeutics Co., Ltd., they cannot meet the requirements of stability experiments, or It is not easy and costly. Considering the long-term needs and the current epidemic situation, there is an urgent need for a hypochlorous acid disinfectant that can be stored stably and can effectively inactivate bacteria and viruses.

Abstract

A hypochlorous acid disinfectant that can be stored stably, which contains iodate in slightly acidic oxidation potential water, and one or more of sulfate, carbonate, dihydrogen phosphate, dihydrogen phosphate and bicarbonate Various.

Description

technical field [0001] The invention relates to a hypochlorous acid disinfectant which can be stored stably. Background technique [0002] 84 disinfectant is a product widely used in killing bacteria and viruses, preventing diseases and inhibiting the spread. It is mainly used for disinfection of object surfaces and environments. It is now widely used in hotels, tourism, hospitals, food processing industries, and households. Sanitation and disinfection. 84 disinfectant has ideal disinfection effect, low price, convenient use, broad-spectrum and high-efficiency sterilization characteristics, but it is irritating and corrosive. Gloves should be worn when handling due to skin irritation. 84 disinfectant is generally passed through chlorine gas (Cl 2 ) reacted with sodium hydroxide (NaOH), [0003] Cl 2 +2NaOH=NaClO+H 2 O+NaCl [0004] Sodium hypochlorite in the reaction product is the main component of the disinfectant. It can be obtained by or by the action of bleachin...
