How do you dilute 91% isopropyl alcohol to 70?
If you find only 91% isopropyl alcohol available buy it and dilute it to 70%, because the 30% water makes it more effective at killing virus.

What alcohol is best for disinfecting?
Isopropyl alcohol, particularly in solutions between 60% and 90% alcohol with 10 – 40% purified water, is rapidly antimicrobial against bacteria, fungi, and viruses. Once alcohol concentrations drop below 50%, usefulness for disinfection drops sharply.
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. Isopropyl alcohol is often used as an antiseptic for this reason.
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.
How do you make 70 alcohol hand sanitizer?
2/3 cup rubbing alcohol of at least 70% alcohol concentration. *When using rubbing alcohol with higher alcohol concentrations, add water to the mix.
Can you dilute isopropyl alcohol with water?
While it is generally okay to use it at the 70/30 ratio, many detailers prefer to dilute it down to a 50/50 (Alcohol to Distilled Water) ratio for optimal results. …
What water should I use to dilute isopropyl alcohol?
With that said, the reason laboratories use distilled water to dilute, is to minimize the additional impurities typically found in tap water.
Why is 70 Alcohol a better disinfectant than 95 alcohol?
Ethyl Alcohol is also a slightly better virucide than IPA. A 70% solution of Ethyl Alcohol 95% kills organisms by denaturing their proteins and dissolving their lipids and is effective against most bacteria, fungi and many viruses, but is ineffective against bacterial spores.
Is 70 or 91 isopropyl alcohol better?
A lower percent-alcohol means there’s more water diluting the mix in the bottle. 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.
Can you mix 50 and 91 isopropyl alcohol?
70 is pretty much right in between 91 and 50, so a mixing equal amounts should get you close enough. The error in the mixing is probably smaller than the variability in the products. A 50/50 solution would be sufficient. But you only need sanitizers when soap and water are not available.
Can you dilute 99 isopropyl alcohol with tap water?
Use distilled or reverse osmosis water, or boiled, cooled and filtered tap water. You don’t want to be adding impurities. 70% isopropyl alcohol solution is used to disinfect for coronavirus.
How do you dilute 99 isopropyl alcohol to 75%?
TO MAKE A STANDARD SOLUTION (70%): Dilute by adding 1 part water to 2 parts of this 99% Isopropyl Alcohol.
