Nolla Hand Sanitizer Foam verified effective against norovirus and coronavirus

The virucidal effectiveness of Nolla Antimicrobial’s Hand Sanitizer Foam was studied against norovirus and coronavirus according to EN 14476 standard test method (screening test only) by independent and accredited testing laboratory MikroLab GmbH (Bremen, Germany).

The tests found that Nolla Hand Sanitizer Foam has a >99.99% activity against coronavirus within 60 seconds using 80% assay, which equals 72 ppm silver ion concentration. Activity against norovirus was measured at >99.99% within 2 minutes of using 97% assay, which equals 87 ppm silver ion concentration.

Middle East Respiratory Syndrome (MERS) is a viral respiratory illness caused by Middle East Respiratory Syndrome Coronavirus (MERS-CoV). MERS-CoV is closely related to bat coronaviruses HKU4 and HKU5 (lineage 2C) which share more than 90% sequence identity. Due to the great similarity in sequence MERS is considered to belong to the same species (Genus betacoronavirus) by the International Committee on Taxonomy of Viruses (ICTV).

The virus used in Nolla Hand Sanitizer Foam’s screening test, the bovine coronavirus, also belongs to the genus of betacoronaviruses. Due to biosafety reasons the bovine coronavirus was used as a surrogate of MERS-CoV. Therefore Nolla-based biocides like Nolla Hand Sanitizer Foam and Nolla Surface Disinfectant Spray can be expected to be highly effective against MERS if tested according to complete EN 14476 standard test.
