![]() The experiments were conducted at two laboratories by either the introduction of aerosolized GP into MS2-containing air or by the introduction of MS2 into aerosolized GP-containing air. ![]() In the present study, researchers investigated the rate of MS2 (ATCC 15597-B1) inactivation by undiluted GP.Įxperiments were conducted to measure the reduction in airborne concentrations of viable MS2 in the presence of several GP concentrations that ranged between 0.02 mg/m3 and 0.5 mg/m3, The corresponding concentration range of TEG was between 0.01 mg/m3 and 0.29 mg/m3 from 60 minutes to 90 minutes, taking into account the natural die-off and settling (NDOS) of MS2. However, the efficacy of TEG against airborne pathogenic organisms needs to be investigated. GP is a mixture of triethylene glycol (TEG), propylene glycol and water designed to provide continual antimicrobial treatment for air. To minimize exposure to SARS-CoV-2 and reduce coronavirus disease 2019 (COVID-19) incidence, it is essential to develop additional protection layers. Study: The efficiency of Grignard Pure™ to inactivate airborne SARS-CoV-2 surrogate. This non-enveloped viral microbe has been used widely as a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) surrogate. In a recent study posted to the bioRxiv* preprint server, researchers characterized the efficacy of Grignard Pure™ (GP) in inactivating MS2 bacteriophage.
