Ethyl Alcohol (Ethanol) may be most effective alcohol at killing viruses
A couple of key things to know. Research has shown that alcohols have the highest anti-microbial efficacy. Typically Ethyl Alcohol (Ethanol), isopropyl alcohol are used. The activity is broad and immediate. Ethanol appears to be the most effective against viruses; whereas the propanols have a better bactericidal activity than ethanol. The higher the concentration of alcohol does change the efficacy in anti-microbial effect with alcohol content above 80% being significantly better at reducing microbial populations compared to concentrations of 60 - 62%.
