Acidic oxidation-reduction potential water is produced by adding a small amount of sodium chloride solution to tap water and electrolyzing it in a special ion exchange membrane electrolytic cell with a titanium platinum alloy electrode, generating acidic and alkaline oxidation-reduction potential waters at the anode and cathode respectively. Acidic oxidation-reduction potential water will be reduced to water and a small amount of chloride when exposed to air, sunlight, organic matter, or heated above 40 degrees.
Appearance: colorless, non-toxic, and almost non-irritating liquid
Effective Chlorine Concentration: 30-50 (mg/L) pH Value: 2.3-3.0
Oxidation-Reduction Potential (ORP): 1100mV-1150mV
Acidic oxidation potential water is a type of acidic disinfectant generated through the treatment of ordinary tap water with a small amount of sodium chloride using an acidic oxidation potential water generator. The tap water with high purity (99.9%) sodium chloride is mixed to a concentration of 1‰-5‰ (adjusted according to different water qualities). The mixture is then electrolyzed in a multi-cell electrolysis tank with a membrane (positive ion membrane) and a special electrode (titanium alloy). Strongly acidic cathodic water flows out from the positive electrode. The oxidation-reduction potential of acidic oxidation potential water is greater than 1100mV, the pH value is less than 2.7, and the hypochlorite content is 20-30ppm. This environment is not suitable for any pathogenic microorganisms to survive. Due to the different bacterial species, the required pH for the growth and reproduction of microorganisms generally ranges from 4 to 9. However, the most suitable pH range for the growth and reproduction of most microorganisms is relatively narrow. The optimal pH value for bacteria is between 4 and 6. A few bacteria, such as acetic acid bacteria and some sulfate-reducing bacteria, have a pH range of 2-4. Generally, actinomycetes grow under weak alkaline conditions. The oxidation-reduction potential also has a significant impact on the growth of microorganisms. The oxidation-reduction potential required for the growth of various microorganisms varies. The oxidation-reduction potential for anaerobic microorganisms is less than 100mV, while that for most aerobic microorganisms is between 300-400mV. In addition, the effective chlorine components in acidic oxidation potential water, such as hypochlorite, peroxide, and OH radicals, are the same as the active oxygen that neutralizes neutrophil bactericidal action. Therefore, high potential, low pH, and effective chlorine constitute the strong disinfection basis of acidic oxidation potential water.
Experimental results have shown that acidic oxidative potential water can deactivate the surface antigen of hepatitis B virus within 30 seconds, kill E. coli and Staphylococcus aureus within 20-30 seconds, and kill bacterial spores within 30 minutes. After being exposed to light and air for a certain amount of time, acidic oxidative potential water can be restored to ordinary water and discharged without polluting the environment. As a new, efficient, fast-acting, broad-spectrum, safe, convenient, and economical disinfectant, acidic oxidative potential water has been widely accepted. Due to its reliable and quick sterilization effect, as well as no adverse reactions and toxic side effects like heavy metal disinfectants or chemical disinfectants, and no residual toxicity, it has no irritation to human skin. As there are no shape-forming agents in the acidic oxidative potential water, it is reasonable to believe that it is a physical disinfectant. At the same time, the high potential of acidic oxidative potential water can promote tissue healing. Given these advantages, acidic oxidative potential water can be used as a good treatment for various clinical infections, especially severe and complicated wound infections. Acidic oxidative potential water is easy to obtain, low in price, and easy to use and master.
According to the effective chlorine theory, in a certain acidic environment (pH: 2.3-3.0) and under high oxidation-reduction potential conditions (ORP ≥ 1100mV), the main component responsible for the sterilization of acid oxidation potential water is the trace amount of effective chlorine (30-50mg/l), while H2O2, OH¯, and new ecological oxygen also play a role in killing bacteria. Acid oxidation potential water destroys the living environment of microorganisms, changes the cell membrane potential, enhances the permeability of the cell membrane, causes cell swelling, destroys the metabolic enzymes and nucleic acids inside microorganisms, and causes microorganisms to die quickly.
(1) Wide spectrum of antimicrobial activity: can kill all pathogenic microorganisms (bacteria, spores, viruses, fungi, spirochetes, etc.).
(2) Fast-acting: complete bacterial inactivation takes only a few tens of seconds, and viruses lose their antigenicity completely.
(3) Convenient to use: ready to use, no need for preparation, tap water, and sodium chloride source.
(4) Colorless, odorless, non-irritating to the skin.
(5) Non-toxic, harmless, with no adverse effects, and no pollution to the environment.
(6) Low cost.
Broad-spectrum, fast-acting: can destroy HbsAg and HIV within 30 seconds, and can also kill bacteria and other pathogenic microorganisms, and spores within 10 minutes.
Non-toxic and environmentally friendly: acid oxidation potential water is harmless to the human body, and the discharge after disinfection can be reduced to normal water and a small number of harmless compounds combined with organic matter.
Economical and convenient: the raw materials are tap water and sodium chloride solution, and the cost is much lower than that of other disinfectants.
1) Disinfection of environment and object surfaces - Applying acidic oxidation-reduction potential water for cleaning and wiping floors, counter-tops, and bed sheets in wards. Marking methods demonstrate that the MRSA count on the ground clearly disappears or survives at a rate of 50% of the cost of professional cleaning companies' disinfectants.
2) Air disinfection - When using acidic oxidation-reduction potential water for aerosol disinfection of air, it is easier to revert to ordinary water and reduce the disinfection efficacy due to increased contact area between the mist particles and air. Therefore, large amounts should be used and repeated multiple times per day in air disinfection, especially during flu outbreak seasons.
3) Dental disinfection - Experimental evidence shows that there are over 80 different kinds of bacteria inside human oral cavities. During dental treatment, traditional oral mouthwash mainly uses distilled or filtered water, which cannot achieve the goal of killing bacteria in the oral cavity. The use of acidic oxidation-reduction potential water for oral rinsing and disinfection of dental instruments is the most effective and simple method to prevent cross-infection in dentistry. Additionally, because this method has non-irritating odors, patients are more receptive to it. Multiple rinses should be performed during disinfection to eliminate the effects of saliva.
4) Disinfection of medical equipment and all kinds of endoscopes - Corrosion-resistant medical equipment can be disinfected with acidic oxidation-reduction potential water after being cleaned and dried. The acidic oxidation-reduction potential water container should have a lid, avoid light, and be corrosion-resistant. The entire repair and disinfection process is one-time: meaning that the disinfected items should be put in all at once, without adding them at any time. The acidic oxidation-reduction potential water used for disinfection should be one-time use only and should not be reused. It should be discarded to prevent the acidic oxidation-reduction potential water from losing its disinfection and sterilization abilities due to oxidation-reduction reactions. Traditionally, hospitals have used chemical disinfectants for soaking or wiping various endoscopes during disinfection. However, these disinfectants have strong skin irritants, higher usage costs, and require pre-preparation. Acidic oxidation-reduction potential water eliminates these shortcomings, thereby greatly facilitating the work of medical staff.
5) Skin disinfection - Using acidic oxidation-reduction potential water to wash and rinse the hands of medical staff for 30s-1min can achieve the standard of hygienic hand washing.
6) Clothing disinfection- Soaking contaminated clothes in acidic oxidation-reduction potential water for 30 minutes can kill all pathogenic microorganisms, including spores. It can greatly improve the permeability of the blood cell membrane and rapidly dissolve it, making it very effective at removing blood stains.
