It’s widely recognized that ethanol in this concentration is effective against many viruses and bacteria. The World Health Organization suggests that 70% ethyl alcohol is superior to isopropyl alcohol against the influenza virus, however, both provide adequate germicidal properties. Both alcohols are flammable and both are used as disinfectants. Ethyl alcohol consists of 2 carbon atoms while isopropyl alcohol has 3 carbon atoms. Generally, the antimicrobial activity of alcohols is significantly lower at concentrations below 50% and is optimal in the 60 to 90% range. Ethyl alcohol, also known as ethanol, jumped in as the most economical and readily available replacement alcohol. Ethanol is more dehydrating, and we can feel that when we use it on our skin.

Isopropyl alcohol pricing was outrageous and hand sanitizer manufacturers began looking for an alternative for alcohol. That evaporation factors into our comfort too. The key difference between ethyl alcohol and isopropyl alcohol is that ethyl alcohol is a primary alcohol while isopropyl alcohol is a secondary alcohol. (That same quicker evaporation rate is why we use rubbing alcohol to clean electronics.) Isopropyl, on the other hand, is produced by the hydration of propene or fermentation by bacteria. isopropyl alcohol compared favorably with ethyl alcohol as a menstruum for Camphorated Opium Tincture and Belladonna Tincture. Ethanol and isopropyl alcohol are similar small molecules but differ in the location of the alcohol group on their chemical structures. Isopropyl alcohol has greater lipophilic properties than ethyl alcohol and is less active against hydrophilic viruses (e.g., poliovirus) (259). It can make our skin feel tight and dry. of isopropyl alcohol into it.
