Physan-20 Kill Coronavirus?

[katsucats]

I wanted more specific information. Of course I would not put any of this on my skin voluntarily. I would only put it on by spillage or for disinfecting. It's like I would not drive voluntarily lol. I would only drive if I have to go somewhere.

But anyways, in case anyone is interested, here are the facts that I found. There is an OSHA-GHS criteria from 1-5 (1 being the most toxic). Undiluted Physan 20 is rated 4 for acute toxicity for oral ingestion, and 4 for acute toxicity for dermal, and 1 for eye damage (!). These numbers mean that a lethal dose of Physan 20 is between 300-2000mg/kg if you eat it, and between 1000mg/kg if you touch it. Specifically it is 506mg/kg if you eat it, and somewhere near 2000mg/kg or above if you touch it.

This is actually somewhat better than 70% ethyl alcohol, since while hand disinfectant isn't on the GHS criteria list since its oral LD50 is 7040mg/kg, you also never use Physan 20 undiluted. At 3 tablespoons per gallon necessary to kill viruses, that's about 1% by volume. The oral LD50 of that would be 50600mg/kg, and the dermal LD50 of both the Physan 20 and ethyl alcohol would be below the scale.

So, while Physan 20 is bad for eye damage and prolonged inhalation, I would not worry about spilling some diluted solution any time soon.
