Recipe for Making Your Own Hand Sanitizer

posted by Jason Kottke   Mar 12, 2020

Many stores have long since sold out of hand sanitizer in the US and washing your hands is a better move anyway, but if you’d like to have some sanitizer on hand for when you can’t get to a sink, the World Health Organization has you covered. The WHO recipe is for making 10-liter batchs, so Popular Science helpfully scaled it down to a more reasonable size:

1 cup 99% isopropyl alcohol
1 tablespoon 3% hydrogen peroxide
1 teaspoon 98% glycerin/glycerol
1/4 cup, 1 tablespoon, and 1 teaspoon sterile distilled or boiled cold water

To the alcohol, add the hydrogen peroxide & glycerin and stir or shake if you’re mixing in a container with a lid. Then add the water.

For COVID-19 prevention, the CDC recommends a hand sanitizer that contains at least 60% alcohol; this recipe will end up being about 75% alcohol. The Popular Science piece also includes another recipe for a hand sanitizing gel that’s much closer to store-bought gels that involves mixing isopropyl alcohol, aloe vera gel, and tea tree oil. They also note that vodka does not contain enough alcohol to meet the CDC’s recommendation, especially when mixed with the other ingredients.
