How to make hand sanitizer | MNN – Mother Nature Network
You’ll need to use about 90 milliliters of rubbing alcohol, also known as isopropyl alcohol, for every 10 milliliters of aloe vera gel, microbiologist and germ expert Dr. Philip Tierno tells MNN. Most isopropyl alcohol is about 70% alcohol by volume, says Tierno, professor of microbiology and pathology at NYU School of Medicine and NYU Langone Medical Center. Check the label to be sure. The alcohol sanitizes your hands but can be drying, so the aloe vera gel helps moisturize them.
