What''s the Difference Between Ethyl Alcohol and Isopropyl Alcohol?

20/7/2020· 100 percent isopropyl alcohol is less effective than 65 or 70 percent because higher concentrations evaporate more quickly. This means that it cannot necessarily kill germs and viruses before it evaporates. Adding hydrogen peroxide or water allows the solution to do it''s "job" longer, making it more effective at killing germs.
