Physan-20 Kill Coronavirus?

AND if you're trying to kill the coronavirus, regular soap and water will do the trick -- it's better than anything else for your hands.

If you want to disinfect surfaces, you could do:

• 78% ethanol for 30s
• 70% 2-Propanol for 30s
• 0.21% Bleach for 30s
• 0.5% Hydrogen Peroxide for 1 min

When it is or was relatively cheap and bought them, I had and still have a bunch of isopropyl alcohol bottles, each bottle 250 ml. I use that to spray on things like fuel/gas bowser handles, elevator buttons, door handles, door knobs etc, before I touch them. The bottles just say 99.8 percent isopropyl.

The most efficient thing to do is to actually spray your hands after touching anything dubious -- that way you can touch all the things you want, and THEN disinfect your hands directly.

Spraying your hands directly is fairly important because the most important thing when disinfecting is contact time. You need to wait anywhere from 30s to a few mins of the disinfectant touching an item before the item is safely disinfected. This is why you see "contact time" listed in the EPA's table. If you do it the other way around, you have to wait every single time, which can cause problems in public. Also, strangers don't always take kindly to you spraying an unknown substance onto surfaces that they are going to touch next haha

So if you're spraying something with IPA, and touching it directly after, there's some chance that you're getting "live" contaminants on you.

And again, it's important to stress that this particular virus cannot infect humans through skin contact. But it can infect someone if they touch a contaminated surface, and then touch their eyes/nose/mouth. This is why it's important to train yourself to not touch those areas in public -- "an ounce of prevention is worth a pound of cure"

hahaha. That's true hypo! I had so far been doing this at work, when there's pretty much nobody there. And when I spray, my hands and fingers are wet with isopropyl for a little while. I have the 'purell' sort of stuff too, just in case.

You're right about those precautions. That virus is quite formidable.

Interestingly, even though I'm a person (human) and on our side - the people's side, I recently thought (and thought of this before lots of times in the past) ---- that the virus is certainly spreading and causing issues for people and among people. But then looked at ourselves too, which also brought up the old (but maybe unoriginal) view from the very old Matrix movie ----- about how humans are pretty much on the same level as virus/bacteria. Doing similar or even much more damage to the earth and the wildlife etc. It's all natural though of course. All part of nature.

I didn't see this earlier. Coronavirus are easy to inactivate. Plain soap and water inactivates coronaviruses at least as well as anything else. Chinese medical reports say they disinfected hospital rooms with 3% hydrogen peroxide.

[Orchid Whisperer]

e.s., you are totally right about the soap and water.

I have always heard that soap and water is preferred. Sanitizer may be used where soap and water is either unavailable or impractical.

[rbarata]

Dish detergent is the best.

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.

[SouthPark]

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

Please do not use this to decontaminate surfaces that you plan on touching soon after

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