Studies find mouthwash containing 0.07 percent of cetypyridinium chloride can combat coronavirus.
Over-the-counter mouthwash can kill coronavirus within 30 seconds of exposure, a study has found.
Scientists at discovered mouthwash containing at least 0.07 percent cetylpyridinium chloride (CPC) showed “promising signs” of reducing transmission of the virus.
Researchers tested eight mouthwashes with different ingredients that are available in pharmacies or drugstores in Germany. They mixed each mouthwash with virus particles and an interfering substance, which was intended to recreate the effect of saliva in the mouth. The mixture was then shaken for 30 seconds to simulate the effect of gargling.
They then used Vero E6 cells, which are particularly receptive to Sars-Cov-2, to determine the virus titer. In order to assess the efficacy of the mouthwashes, the researchers also treated the virus suspensions with cell culture medium instead of the mouthwash before adding them to the cell culture.
