A new study from the UK’s Cardiff University found that widely available mouthwashes kill the virus within 30 seconds of exposure.
There are encouraging signs that fluids containing 0.07% cetyl pyridinium chloride (CPC) could be used as a means of fighting the coronavirus, scientists said.
Laboratory research shows that mouthwash kills the coronavirus in saliva. However, there is still no evidence of its effectiveness as a therapeutic agent, since it does not enter the respiratory tract or the lungs.
These findings have not yet been peer-reviewed, but they are in line with previous tests that have shown CPC-containing fluids can help reduce SARS-CoV-2 viral load.
