How to make homemade hand sanitizer according to the WHO recommendations.
12 fluid ounces 91% rubbing alcohol*
2 teaspoons emollient (glycerin, fractionated coconut oil, or other skin-friendly nut or seed oil)
1 tablespoon 3% hydrogen peroxide
1 tablespoon + 2 teaspoons distilled or boiled water
Optional: A few drops essential oils per bottle
In a very clean glass lidded jar, add alcohol, hydrogen peroxide, and distilled water (see alternate measurements below.) Add the emollient and shake vigorously until combined. Pour into small spray bottles and label. If desired, add a few drops of essential oils per bottle. You may need to shake the mixture between fillings.
99% alcohol: 12 ounces alcohol + 1/4 cup + 2 tablespoons water
95% alcohol (Everclear): 12 ounces alcohol + 1/4 cup + 1 1/2 tablespoons water
91% alcohol: see recipe above
70% alcohol: 12 ounces alcohol + 1 1/2 tablespoons water
Anything less than 70%: Do not use
Basically, for every 8% alcohol below 99%, remove 1 tablespoon water. Thank you VERY MUCH to my very smart son Clark who helped me with the math.
