So... I would not suggest that anyone inject disinfectants, Physan or not. Of course any such disinfectant is rough for the skin, but is 0.4% diluted Physan really more dangerous than 70% alcohol? Sure, prolonged exposure to Physan may be problematic, but we all know what prolonged exposure to alcohol does. Apples to apples.

With that said, I'm not an expert, so I'll accept any answer if someone more knowledgeable could directly compare the typical 70% alcohol hand sanitizer vs Physan. I have spilled 1% (3 tablespoon to gallon) Physan here and there and thankfully have not gotten any organ failures. But again, I've also gotten plastered from Vodka.

I would not voluntarily put Physan on my skin. I only put 70% alcohol on my skin when soap and water are not available.

Totally! I definitely wouldn't put physan on my skin, and wouldn't allow physan to get on me.

The isopropyl alchohol spray could probably be used. Just spray, then put the bottle down, then rub hands together to get the liquid all over, then allow some time for it to act and do its thing before resuming regular activities.

Otherwise, just use the regular gel hand sanitiser hehehe

That says it all hehehe. Just don't do it! Good information hypo.

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.

The straight stuff can be corrosive, especially to mucus membranes. When diluted, I only worry about getting it in my eyes or inhaling droplets.

I keep a spray bottle of diluted material in the medicine cabinet to spray on my electric toothbrush (the junction where the brush head attaches to the base) and the cutting heads of my in-the-shower shaver. Both can hold water and grow mold - but not any longer.
