Physan-20 Kill Coronavirus?

[Ray]

I would guess the answer is “yes”.

Physan 20 is of the same class of quaternary ammonium compounds as hospital disinfectants. It consists of alkyl dimethyl benzyl chlorides and alkyl dimethyl ethyl benzyl chlorides.

Some disinfecting wipes we picked up at the grocery store contain those and octyl- versions, but totaling only 0.31%. A tablespoon-per-gallon is 0.39%.

I use a single liquid product for shampoo, body wash and shaving lubricant in the shower. Back when I was on the road 5-6 days a week and spent a lot of time in the hot end of glass plants (ambient temperature about 115-120F), I would “spike” the soap product with a half teaspoon Physan per bottle to make it more strongly antibacterial. Did that for several years and never had a problem.
