1. Check the technical patent number, inspection report number and filing information of disinfection products. First of all, the definition of micro-acid is that the pH value is between 6.20 and 6.80, and pH >；; 7 is not hypochlorous acid, pH2. Check whether the pH value of the product is clearly marked. During the operation of the slightly acidic hypochlorous acid water generating equipment, the allowable range of pH value is accurately and intelligently controlled between 5.0 and 7.0, and it will automatically stop if it exceeds the range. The fluctuation range of any value in the generation process is controlled within a narrow range of 0.05 to ensure the stability, safety and effectiveness of the product. It can be stored in dark environment for more than 18 months.
3. High concentration of hypochlorous acid is easy to get, and low concentration is rare. It is extremely difficult to produce stable low-concentration hypochlorous acid water at low concentration, while high-concentration products are basically raw materials. The higher the concentration of hypochlorous acid product, the more unstable it is. Therefore, it is necessary to add stabilizers before filling into the market. The instability of products means that the safety and effectiveness can't reach the stability index. The US FDA and the Japanese Ministry of Health, Labor and Welfare have identified weak acid hypochlorous acid water with available chlorine content less than 80mg/L as food additive, which is widely used as sterilization and fresh-keeping water in food processing industry. The available chlorine content of Iris brand hypochlorous acid water is set to 100mg/L, which has been widely used in Japan's animal husbandry, agriculture, water treatment, hospitals, public facilities and other fields for more than ten years, and has maintained a safety disinfection record of 0 accidents and 0 complaints for a long time. Known by Japanese consumers as the safest disinfectant in the 20th century, slightly acidic hypochlorous acid water is equivalent to water (functional water). The sterilization speed of hypochlorous acid water is 80~ 100 times that of common chlorine-containing disinfectants, and the sterilization effect of 100mg/L is equivalent to that of 1000 ~ 4000 mg/L sodium hypochlorite products.
