Evaluation of Virucidal Activity of Residual Quaternary Ammonium-treated Surfaces on SARS-CoV-2

This content is a preprint and has not undergone peer review at the time of posting.

Abstract

A commercially available and EPA/PMRA registered quaternary ammonium antimicrobial formulation was applied to stainless steel carrier disks and sent to two virology research institutes to independently determine whether samples treated with SiQAC-C18 antimicrobial material could deactivate deposited SARS-CoV-2 virions on contaminated surfaces. The results independently support a sustained antiviral effect imparted from these treated surfaces by both SARS-CoV-2 virion destruction and degradation of viral RNA. These preliminary results indicate the SiQAC-18 treated surfaces could play an important role in mitigating the communicability and fomite transmission of SARS-CoV-2.
