Active Chlorine Dioxide Oral Rinse

Chlorine Dioxide (CLO2) was discovered by Sir Humphrey Davy in 1811. He produced it by acidifying potassium chlorate with sulfuric acid. In 1940 M. C. Taylor produced CLO2 by adding an acid or chlorine to Sodium Chlorite. It is by the formation of CLO2 from Chlorite that drinking water treatment is currently practiced. CLO2 has been used as a mouthwash, by the acidification of Chlorite since the 1980s, and by the reaction of Chlorine (Clorox™) with Chlorite since the early 1990s. In the mid 1990s Dr. George discovered a method of forming CLO2 by the reaction of Potassium Iodide with Chlorite.

CLO2 is probably the most extensively tested disinfectant in history. This is because not much was known about it, where as experience with chlorine extended in practice for over a hundred years. It is a safe and effective biocide, and has been used for disinfecting, and eliminating odors in water for about 70 years; and nearly as long for whitening in the paper making industry. It has also been used for biofilm control in commercial water cooling towers.
