isopropyl alcohol is 91% alcohol, so I’m making mine with 90% isopropyl alcohol per 2 oz bottle (a bit less then they recommend) and 10% aloe vera juice or gel along with 15 drops of a combination of lavender and tea tree essential oils, both of which are used to kill germs. Also, from what I understand, your hands should stay wet for about 1 minute to be effective at killing the corona virus.
I applaud New York for making their own for their residents!
Again, if you have better information, please pass it along, I would appreciate it.
In the meanwhile, please, no french kissing strangers and stay healthy and safe!
