per amazon Physan 20 is a odorless, and colorless liquid. It is a powerful cleaner and disinfectant when used properly. The manufacturer recommends you only use 1ml for every 10 gallons, and THEY ARE SERIOUS! Using too much Physan 20 can be toxic and deadly for any plants or fishes living in your pond, aquarium or reservoir. ---------- Post added at 09:20 PM ---------- Previous post was at 09:07 PM ---------- One of the assisted living homes with 55 residents, that I am helping with supplies, will be out of hand sanitizer. I only have part of a bottle left to use in my car, so I am trying to make my own or figure out something that is safe. There is no glycerin or aloe vera in my town. I am slow to be reading about using that with alcohol. Vodka is 40% compared to 70% isopropol that is the only alcohol known to kill the virus per research. I do not have any left so I mixed some vodka with some mouthwash that is chlorohexidine, but only a tiny percentage, I am going to use it in my car to wipe down steering wheel and gear shift if I have to leave my home.c but that gave me another idea for the assisted living and remember Hepa Cleanse, stronger than the mouthwash, used by drs to scrub with water prior to surgery/delivering babies. So I got the only bottle they had at walgreens, and had them order several bottles for the assisted living center if they choose. |
I'm certainly not suggesting you simply run out, buy and use it, but a 1.5% solution of glutaraldehyde is available at most pet stores labeled "Flourish Excel". Glutaraldehyde is used for cold sterilization of surgical instruments, and surfaces in laboratory environments. I would strongly suggest you look into the compound yourself before using it, and of course it's suitable for external use only!

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. |

Alright, so there is a BIG "danger" warning on the Physan bottle. On the back, it says to not get it on your skin:

Quaternary ammonium salts can cause some people to have allergic reactions or cryptic irritant effects. I'd stick to using preparations that are intended for home use and are diluted accordingly. Just because Ray put it in his shampoo (LOL) does not mean it's safe.

I read a recent article that talked about the use of NIH approved greenhouse disinfectants to avoid shipping contaminated plants if a nursery worker has COVID-19, and Physan was not on the list. Sorry, I no longer have the article or reference. |
