Frequently Asked Questions
Why does the alcohol concentration matter?
Since your starting alcohol is not 100 percent pure, you need more of it by volume than the target percentage alone to reach the correct final concentration once diluted with other ingredients.
What is the minimum recommended alcohol concentration for hand sanitizer?
Health authorities including the CDC recommend hand sanitizer contain at least 60 percent alcohol to be effective against most germs.
What other ingredients are typically used?
Aloe vera gel is commonly used to make the alcohol gentler on skin and give the sanitizer a gel-like consistency, though it dilutes the alcohol concentration and must be accounted for in the ratio.
Is homemade hand sanitizer as effective as commercial products?
When mixed correctly at the recommended alcohol concentration, homemade sanitizer can be effective, but commercial products undergo formal testing and quality control that homemade batches do not.
