Covid: Mouthwash 'can kill virus in lab in 30 seconds'
Mouthwash can kill coronavirus within 30 seconds of being exposed to it in a lab, a scientific study indicates.
Scientists at Cardiff University found there were "promising signs" that over-the-counter mouthwashes may help to destroy the virus.
The report comes ahead of a clinical trial on Covid-19 on patients at the University Hospital of Wales.
Dr Nick Claydon said the study could lead to mouthwash becoming an important part of people's routines.
While the research suggests use of mouthwash may help kill the virus in saliva, there is not evidence it could be used as a treatment for coronavirus, as it will not reach the the respiratory tract or the lungs.
Dr Claydon, a specialist periodontologist, said: "If these positive results are reflected in Cardiff University's clinical trial, CPC-based mouthwashes... could become an important addition to people's routine, together with hand washing, physical distancing and wearing masks, both now and in the future."
The university report states that mouthwashes containing at least 0.07% cetypyridinium chloride (CPC) showed "promising signs" of being able to eradicate the virus when exposed to the virus in a lab.
While the report is yet to be peer reviewed, it supports another recent study which found CPC-based mouthwashes are effective in reducing viral load.
How many deaths have there been?

Do we ever follow the science?
A clinical trial will look at whether it helps to reduce levels of the virus in the saliva of Covid-19 patients at the hospital in Cardiff, with results expected early next year.
Prof David Thomas, who is leading the study, said the initial results were encouraging, but the clinical trial would not produce evidence of how to prevent transmission between patients.
"Whilst these mouthwashes very effectively eradicate the virus in the laboratory, we need to see if they work in patients and this is the point of our ongoing clinical study," he said.
"The ongoing clinical study will, however, show us how long any effects last, following a single administration of the mouthwash in patients with Covid-19."We need to understand if the effect of over-the-counter mouthwashes on the Covid-19 virus achieved in the laboratory can be reproduced in patients."

We often deem granted the action of disinfectants without fully understanding how they work. Not only are there differences within the action of the antimicrobial ingredients,
but they're also are differences counting on the concentration of a chemical that's used which will impact the action of an agent or physical process.
In general, disinfectants have three mechanisms of action or ways in which they affect or kill an organism: Cross-linking, coagulating, clumping; structure
and performance disruption; and oxidizing.
All the disinfectants contain alcohol and many chemicals that directly or indirectly affect us.
So after several years of research, we have introduced Citrobioshield which is made using FDA's GRAS listed natural and organic ingredients.
