Of course, it should also never be ingested.
How do you dilute 95% alcohol to 75%?
All we have to do is to subtract the volume of 95% alcohol from the volume of 75% alcohol, in this case: 1.26 x 1.00 = 0.26 l = 260 ml….This means that you have 75% of pure alcohol and 25% of water:0.75 x 1000 = 750 ml.This is the amount of pure alcohol.0.25 x 1000 = 250 ml.This is the amount of water.

Which is a better disinfectant ethyl alcohol or isopropyl alcohol?
Isopropyl, on the other hand, evaporates at a similar rate and destroys bacterial and viral cells by the same mechanism. However, it is not as effective at dehydrating living tissue and so is a better solution for disinfecting skin than ethanol.
Is denatured alcohol a disinfectant?
Denatured Ethanol (DE) or Isopropanol (IPA)? Denatured Ethanol is considered more effective as a virucidal disinfectant, as isopropanol is not effective against non-enveloped viruses.
