Virucidal activity of a proprietary blend of plant-based oils (Viruxal) against SARS-CoV-2 and influenza viruses – an in vitro study

Kristjánsson, Jón Magnús; Rolfsson, Óttar

Background The emergence of a novel coronavirus known as SARS-CoV-2 resulting in a global pandemic COVID-19 has led to a dramatic loss of life worldwide and presented an unprecedented challenge to public health. Viruxal is a medical device in a form of a nasal and oral spay containing a a proprietary blend of plant-based oils which acts against enveloped viruses. The aim of this study was to evaluate the virus deactivation activity of Viruxal against SARS-CoV-2 and Influenza A(H1N1) viruses. Methods An assay to detect virucidal activity was performed with four concentrations of Viruxal on two virus suspensions. Assessments were made based on log reduction values measured from the assay. Results Viruxal exhibited virucidal activity by reducing virus titer more than 90% for the enveloped viruses SARS-CoV-2 and influenza A(H1N1) after 30 minutes contact. Conclusions Viruxal was validated for its potential usefulness as a medical device for treatment and prevention of enveloped respiratory viruses.
