Chlorine dioxide is decomposed to produce a small amount of by-products such as chlorite and chlorate, but it is rapidly decomposed and non-toxic.
Animal testing proves that chlorine dioxide is no problem for primates below 100 ppm (IPCS, International Program on Chemical Safety, 2002)
Chlorite did not produce carcinogenic or tumors as a result of 85-week drinking water at 300-600 ppm concentration in rats (hayashi, 1998).
Chlorates have no specific symptoms such as cancer or tumors in dogs and rats.
Chlorine dioxide does not react with ammonia and therefore does not produce chloramines with high toxicity potential.
Does not generate carcinogenic halogenated organic compounds such as chloroform.
No bromate produced when disinfecting unlike the case of ozone

NeoCL Environmental Assessment-Rabbit Eye Irritation, Skin Irritation Test
Eye irritation and skin irritation test results for rabbit chlorine dioxide (ClO2) high concentration (100ppm) was determined to be harmless
Eye irritation test: 100ml of chlorine dioxide product was applied to the rabbit eye by 0.1ml to evaluate eye irritation
Skin irritation test: Evaluation of irritant reactions such as erythema, skin, and edema through the test according to the "Toxicity Test Standards for Drugs (2005)" of the Korea Food and Drug Administration.

"All of the chlorine dioxide had little skin and eye mucosal toxicity in rabbits and did not show any irritation or adverse reactions even when administered directly to the skin and eye. As a result, even if a product that can be applied to various skin and eyes is developed as a main ingredient of anti-freezer and chlorine dioxide, it was judged to have high safety because it has no irritation or toxicity caused by chlorine dioxide itself."
NeoCL Environmental Assessment- Ecological Toxicity Evaluation of Luminescent Bacteria
Luminescent bacteria ecotoxicity assessment was performed on chlorine dioxide 1mg / L 60 minutes and no ecotoxicity was expressed as 0.0 (TUB).
Luminescent Bacteria Standard Toxicity Evaluation Results
The water pollution process test standard suggests that the standard toxicity test standard of luminescent bacteria should produce 20% to 80% of relative luminescence after 30 minutes of exposure to the following concentrations of substances:
|3.4||3, 5 – dichlorophenol||Relative luminance 20% ~ 80% after 30 minutes exposure|
[copper sulfate 7 H2O same as 9.7mg.L]
[same as potassium dichromate 5.29mg.L]
Animal testing demonstrates that chlorine dioxide is no problem for primates below 100 ppm (IPCS, International Program on Chemical Safety, 2002)
