Are benzalkonium chloride-containing hand rub products an acceptable alternative to ABHR for COVID-19?

While this product is tough on germs, please note it is Alcohol Free. 

The CDC (Centers for Disease Control and Prevention) does not have a recommended alternative to hand rub products with greater than 60% Ethanol or 70% Isopropanol as active ingredients.

Benzalkonium chloride, along with both Ethanol and Isopropanol, is deemed eligible by the FDA for use in the formulation of healthcare personnel hand rubs. However, available evidence indicates Benzalkonium Chloride has less reliable activity against Coronavirus (Covid 19) than either of the alcohols.
