New Study Suggests Mouthwash Can Kill Coronavirus in Saliva in 30 Seconds


Along with hand washing and other hygiene measures, mouthwash could become a routine part of people’s daily habits after preliminary laboratory tests from Cardiff University found it can fight coronavirus in 30 seconds. .

These results, which have not yet been peer-reviewed, come from a 12-week study where it was found that mouthwashes containing at least 0.07 percent Ketipyridinium Chloride (CPC) show “promising signs” of killing the virus.

In laboratory tests, the university scientists worked with several brands of mouthwash, including Listerine and Dentyl. By mimicking the conditions of a person’s naso / oropharyngeal passage, they tested how various ingredients in mouthwash kill the virus.

In his report, entitled Virucidal efficacy of mouthwash components against SARS-CoV-2 in vitro, the researchers note that three of the mouthwashes tested completely eradicated the virus in the laboratory.

These early results from Cardiff are not the same as finding a cure – there is no indication that mouthwash has any impact on the virus if it passes from human saliva into lung tissue, for example.

Dr. Nick Claydon, specialist periodontologist, he told the independent believed the research so far is “very valuable” and added: “If these positive results are reflected in the Cardiff University clinical trial, CPC-based mouthwashes … could become an important addition to the people’s routine, along with hand washing, physical distancing and wearing masks, both now and in the future. “

Next for scientists, a clinical trial will be conducted examining how effective mouthwash is in reducing coronavirus levels in COVID-19 patients at University Hospital of Wales. The results of that study are expected to be published in early 2021.
