Can I use 99 alcohol for sanitizer?
You can buy rubbing alcohol with a concentration of 70% or 99% isopropyl alcohol. Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria.
Is 99% isopropyl alcohol safe for skin?
The only downside of 99% isopropyl alcohol is that, understandably, it needs to be used and stored properly. In this concentration, it is highly flammable, may cause dizziness if used in high quantities in an ill-ventilated area, and can be an irritant to skin and eyes. Of course, it should also never be ingested.

Instead of being activated at about 107˚F/41.6˚C, they turn on at about 93˚F/33.9˚C. Normal human body temperature is in the 98.6˚F/37˚C, so when you drink alcohol, it’s really your own body heat that activates the heat receptors. Therefore, when you chug a ABV beer or take a shot, it warms or burns your throat.
Is it bad if hydrogen peroxide burns?
