Coronavirus is killed within 30 seconds of coming into contact with regular mouthwash, a study has found.
Cardiff University researchers say mouthwashes containing at least 0.07 per cent cetypyridinium chloride (CPC) show ‘promising signs’ for fighting the virus.
Dentyl was the only UK mouthwash brand to take part in the 12-week clinical trial, which was led by Professor David Thomas from Cardiff University.
The report is yet to be peer reviewed but supports another study published last week, which found CPC-based mouthwashes are effective in reducing Covid’s viral load.
The preliminary result comes ahead of a clinical trial into whether using over-the-counter mouthwash has the potential to reduce Covid-19 levels in saliva.
For instance, researchers say iodine mouthwashes have proved very effective against SARS and MERS, two diseases caused by similar coronaviruses.
The latest test builds on promising early results from the team and mimicked the conditions of a person’s naso/oropharynx passage, where the virus thrives.
A clinical trial will next examine how effective mouthwash is in reducing the viral load in the saliva of Covid-19 patients at the University Hospital of Wales in Cardiff.
