DIY Hand Sanitizer Recipe
By Jeff Kantor, PhD
Professor of Chemical & Biomolecular Engineering at the University of Notre Dame
- 1.25 cups 70% isopropyl rubbing alcohol
- 1 tablespoon 3% hydrogen peroxide
- 3 tablespoons aloe vera gel
Mix well. Reuse a dishwasher detergent bottle or a commercial hand sanitizer bottle for application. It will be a little thinner than commercial products but effective. This recipe meets the 60% alcohol requirement for an effective sanitizer, includes the hydrogen peroxide recommended by the World Health Organization and has a little glycerin and aloe for fragrance.
