Physan-20 Kill Coronavirus?

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.

Thanks Ray, I found several other quaternary cleaners on the official list from the CDC. I like the clean smell of physan-20 over lysol. All my hand sanitizer and idinfectant wipes are like 5 years old so not sure how effective they are. Going to make up a spray bottle of physan.

1tbsp a gallon still recommended?

I would strongly suggest you look into the compound yourself before using it, and of course it's suitable for external use only!

Coincidentally I have two bottles of this from my planted fish tank days!
