Is 70 isopropyl alcohol safe for skin?
Most manufacturers sell rubbing alcohol in different formulation strengths, namely 70 or 90 percent rubbing alcohol. As a general rule, 70 percent rubbing alcohol is more friendly for use on your skin.
Is 70% isopropyl alcohol safe?

Isopropyl alcohol vapor is denser than air and is flammable, with a flammability range of between 2 and 12.7% in air. It should be kept away from heat and open flame. Distillation of isopropyl alcohol over magnesium has been reported to form peroxides, which may explode upon concentration.
At what temperature does 70 isopropyl alcohol freeze?
According to the Department of Physics at the University of Illinois Urbana-Champaign, a solution with 30 percent ethanol concentration, or 60 proof, has freezing point of 5 degrees F or -15 degrees C, and one with 40 percent ethanol concentration, or 80 proof, freezes at -10 degrees F or -23 degrees C — therefore, 70 …
