While 70% isopropyl alcohol makes a very effective disinfectant, the more concentrated version of 91% isopropyl alcohol also has some incredibly beneficial uses. This liquid can also be used to clean and disinfect surfaces, and it’s safe to use on skin too. What is the difference between 70 isopropyl alcohol and 91 isopropyl alcohol?
But according to microbiology, 70 percent alcohol is probably more effective than 91 percent for disinfecting—depending on what kind of germs you’re trying to kill. Here’s why a lower-percentage alcohol might be a better weapon against germs:
Make Your Own Disinfectant Spray from 91% Isopropyl Alcohol (Rubbing Alcohol) When it comes to the healthy and safety of your family, friends, and coworkers, only the very best will do. While isopropyl alcohol will kill germs and viruses, we recommend using 100% ethyl alcohol vs 91% isopropyl alcohol for making disinfectant spray.
Which explains why solutions of alcohol are not approved by the Food and Drug Administration (FDA) as a high-level disinfectant.  How does alcohol kill germs? Alcohol is an antimicrobial solution that works by denaturing the proteins of germs.  This in a way, is similar to how soap works. Alcohol unfolds proteins in living cells, which inactivates cell activity or kills the cell completely.
FDA has not cleared any liquid chemical sterilant or high-level disinfectant with alcohol as the main active ingredient. These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores.
Since alcohol is flammable, limit its use as a surface disinfectant to small surface-areas and use it in well-ventilated spaces only. Prolonged and repeated use of alcohol as a disinfectant can also cause discoloration, swelling, hardening and cracking of rubber and certain plastics.
In terms of disinfecting, higher concentrations of alcohol are less effective at killing bacteria. "Certain bugs, such as bacteria, are better eliminated with the use of a less concentrated isopropanol, because higher concentrations cause an external injury that forms a protective wall and shields these organisms," explains Dr. Grigoriy Mashkevich MD, facial plastic surgeon at Specialty Aesthetic Surgery .
Absolutely not. In fact, Dr. Alexis says there is “no evidence that drinking alcohol will help kill viruses and bacteria.”. Again, disinfectants have a much higher alcohol concentration and ...
If you are going to be using rubbing alcohol on your skin please use 70% or even less. 91% is very drying on skin. It removes all the natural oils, natural moisture [water] and all the other 'good stuff' that your skin has to protect it's self. If you do use 91% on yourself your skin will turn a dry chalky gray and need to be remoisturized.
Alcohol has been used as a hand sanitizer since 1888, and the disinfecting qualities of ethanol and isopropanol are well-proven. While washing hands for 20 seconds with soap and water is always preferable, alcohol-based hand sanitizer can be a good alternative, if used properly. Here's what you need to know.
