The oxidation-reduction potential of the acidic oxidation potential water is more than 1100mV, the pH value is less than 2.7, and the hypochlorous acid is 20-30ppm, so that the environment is not suitable for the existence of any pathogenic microorganism. Due to different strains, the pH value required by growth and reproduction of microorganisms is generally between 4 and 9, but most microorganisms have a narrow pH range which is optimal for growth and reproduction. The optimum pH value of the bacteria is 4-6, the optimum pH values of a few bacteria such as acetic acid bacteria and some sulfuric acid bacteria are 2-4, and the general actinomycetes are suitable for growth under the condition of weak base. The oxidation-reduction potential has great influence on the growth of microorganisms, the oxidation-reduction potentials for the growth of various microorganisms are different, the oxidation-reduction potential suitable for the growth of anaerobic microorganisms is less than 100mV, and the oxidation-reduction potential suitable for the growth of common aerobic microorganisms is 300-400 mV. In addition, since hypochlorous acid, hydrogen peroxide and OH groups, which are effective chlorine components in electrolyzed oxidizing water, have the same composition as active oxygen responsible for the sterilization of neutrophils, high potential, low pH and effective chlorine form the basis of strong sterilization and disinfection of electrolyzed oxidizing water.

Experiments prove that: the acidic electrolyzed oxidizing water can inactivate hepatitis B virus surface antigens within 30s, kill Escherichia coli and Staphylococcus aureus within 20-30 s, and kill bacterial spores within 30 min. The acidic oxidation potential water can be reduced into common water after contacting with light and air for a period of time, and has no pollution to the environment after being discharged. The electrolyzed oxidizing water is accepted by people as a novel disinfectant with high efficiency, quick effect, broad spectrum, safety, convenience and economy. Because it has reliable and rapid sterilization effect, does not have allergic reaction like heavy metal sterilization drugs or chemical disinfectants, does not leave residual toxicity, has no toxic or side effect, and has no stimulation to human skin. The electrolyzed oxidizing water is free of any excipient, so it is reasonably considered to be a physical disinfectant. Meanwhile, the high potential of the electrolyzed oxidizing water can promote the healing of tissues.
