Molecular Iodine Oral Rinse Found Effective against SARS CoV-2 ing.


November 13, 2020

Boca Raton, FL – ioTech International today announced that testing has recently been Medical ncompleted at the Institute of Antiviral Research at Utah State University comparing the antiviral efficacy of 4 oral rinses. The testing compared 2 rinses recommended by the American Dental Association in their interim guidance against Covid-19 (1.5% hydrogen peroxide and 0.2% povidone iodine). A third oral rinse, which earned the American Dental Association Seal of Acceptance (0.12% chlorhexidine gluconate) and a molecular iodine oral rinse being developed by ioTech International were also tested. The in vitro testing was conducted at a Level 3 Biocontainment laboratory by university researchers.

Testing was conducted to determine both the cytotoxicity and antiviral efficacy of each of the 4 rinses. The only rinse to demonstrate complete effectiveness against the SARS CoV-2 virus was the molecular iodine oral rinse containing molecular iodine 100 ppm (parts per million). The molecular iodine rinse was completely effective within 30 seconds. The other 3 rinses were only partially effective, even after 60 seconds. Neither of the iodine rinses (molecular iodine nor povidone iodine) were cytotoxic in the testing. Both the hydrogen peroxide and the chlorhexidine gluconate rinses demonstrated toxicity.

Michelle Mendenhall, Principal Investigator at Utah State University stated “The Institute provides evidence-based research exploring the antiviral and virucidal activity of a wide range of compounds. We are pleased to have conducted this study which compares, for the first time, the virucidal efficacy of three oral rinses used in professional dental offices and a newly developed rinse against SARS-CoV-2.”

Rodger Kolsky, Director of R&D at IoTech International stated “Molecular iodine is the only biocidal form of iodine. IoTech International’s unique, patented formulas provide consistently high levels of molecular iodine for our current products and the additional products that we are developing. These test results provide additional confirmation that our products will have a meaningful impact on people’s lives”.

The study details were just published in the International Journal of Experimental Dental Science, a peer-reviewed, scientific journal. A copy of that article is provided below for your convenience. For further information, contact ioTech International. To read the article online, please visit:
