The preliminary lab test results on SARS-CoV-2 build on existing Unilever research published on the biology research platform BioRxiv and follow ongoing discussions in the global medical and scientific community around the potential use of mouthwash as an additional measure to reduce the transmission of the virus.
Research continues, including into the duration of the effect, but a previous study4 on a small group of patients infected with Covid-19 suggest that viral load – the amount of virus particles a person is carrying – may be reduced in the mouth for up to six hours by using mouthwashes containing CPC Technology.
These preliminary test results showing the efficacy of CPC Technology against the SARS-CoV-2 virus are the latest in a large range of studies that are evaluating the efficacy of mouthwash technology against a number of viruses. In the tests we have done, only CPC Technology has to date shown consistently positive results.
“While research has previously been published into the effect of mouthwashes against surrogate coronaviruses, this is the first study in a laboratory to demonstrate that mouthwashes containing CPC can be effective against the actual virus responsible for Covid-19, and that they do indeed lower the viral load in recognised tests of mouthwash use,” says Dr Angela Rasmussen, Associate Research Scientist at the Center for Infection and Immunity at the Columbia Mailman School of Public Health in the US.
Dr Rasmussen adds: “Other research on the duration of effect of CPC in a mouthwash on bacteria and coronavirus would suggest that the reduction in infectious viral load is likely to be sustained over time. This effect has also been demonstrated on a small sample of Covid-19 patients.”
