“I have some aloe vera gel and 70% rubbing alcohol. I thought about combining to make hand sanitizer...”
A month ago I read where the percentage needs to be at least 60% or more. And it loses some of the alcohol if it is old. I have two old bottles that I added straight 99% rubbing alcohol to in order to bring it’s strength. But no - don’t dilute the 70% hand sanitizer.
Or put a spray nozzle on the alcohol bottle. Moisturize at night.
