Welsh Cardiff University scientists discovered that over-the-counter mouthwash which contains 0.07 percent cetylpyridinium chloride showed signs of reducing the transmission of COVID-19.

Cardiff’s Systems Immunity Research Institute tested how effective some  mouthwashes are which contain ethanol or essential oils, CPC and povidone-iodine (PVP-I) at eradicating the virus.

The preliminary study showed that three of these mouthwashes eliminated COVID-19 completely.

Two of the three products contained at least 0.07 CPC and the other product contained 23 percent ethanol with ethyl lauroyl arginate (LAE).

The preliminary study lead and Viral Immunology Reader at Cardiff University Richard Stanton, said that the study adds to “the emerging literature that several commonly available mouthwashes designed to fight gum disease can also inactivate the SARS-CoV-2 coronavirus" upon testing under lab conditions.

“More clinical research is now clearly needed," explained another participant in the study, Professor David Thomas to PA news.

Mouthwash is believed to become a vital addition in combating COVID-19, says Clinical Lecturer and Oral Healthcare Specialist, Nicholas Claydon. However, it is in no way a replacement for COVID-19 treatment or cures.

He urged that people should continue to follow the preventive measures, including washing hands frequently and maintaining social distance.

The result of this study come ahead of the pre-trial which will take place at the University Hospital of Wales in Cardiff. The trial findings are set to be published early 2021.
