We should now use chlorine dioxide, which is beneficial to the environment and harmless to the human body.
Chlorine dioxide has the advantage of being harmless to the human body and beneficial to the environment. With this advantage, it is rapidly taking over the market for sterilization and disinfection, which has been dominated by chlorine-based (LAX) products.
Chlorine dioxide overview
Chlorine dioxide is a material recognized by the World Health Organization to have the highest safety level, and it is safe and effective.
Sterilization and deodorization
Harmless to human body
Environmentally friendly

[Chlorine dioxide VS chlorine (LAX) sterilizer]
| Classification | Aqueous chlorine dioxide | Chlorine disinfectants (HCIO, NaCIO, NaCIO2) |
|---|---|---|
| Classification | Oxygen system | Chlorine (Oxygen) |
| Active ingredient | Oxygen (O2) | duath(CI+O) |
| Sterilization power | 2.5 times or more | 1 |
| Disinfecting power | 5 times or more | 1 |
| Sterilization effect | Most fungi, bacteria and viruses | Some fungi, bacteria and viruses |
| Sterilization pH range | 2~10 | 2-7 (Strong acidity) |
| Permeability | Cell wall and internal structure penetration | Impervious |
| safety | Safe | Danger of contact with skin, airways and eyes |
| Metal corrosion resistance | None | Metal corrosion |
| Fiber bleaching effect | Exists | Fiber discoloration and bleaching |
| Convenience | Can be used up to closed spaces | Inappropriate for spraying, ventilation required |
| Active odor | Weak, volatilized in a short time | Strongly irritating chlorine odor (residual) |
| Disinfection persistence | Maintained | Bacteria regrowth, virus residue |
| Selectivity | Does not react with organic matter | Reacts with organics to produce by-products |
| Disinfection by-products | None | Carcinogen (Trehalomethane, etc.) |
| Protozoa | Removed (Main component decomposition of protein composition) | Partially removed |
| Heavy metal removal function | Removal of iron, manganese, phenol, etc. | Impossible |
Status of usage
It has been used for a long time in developed countries such as the United States and Europe, in a wide range of fields.
In 2006, the U.S. Environmental Protection Agency (EPA) established guidelines for specific uses and applications ranging from drinking water to agricultural, commercial and industrial facilities, swimming pools, and residential facilities.
In Korea, it was approved for use as a sterilizing disinfectant under the Drinking Water Control Act of 1999 (since chlorine dioxide is a water-soluble oxidizing agent, it does not generate carcinogens due to by-products, and has environmentally friendly properties that are easily decomposed by light which make it safe to be used as drinking water).
