Hand Sanitizer Recipe

Here is a DIY recipe from The Lin Lab - Stanford Medicine - Dept. of Neurobiology:

• • Hand sanitizer is just 60-70% ethanol with moisturizers.
  • The ethanol you want to use is 95% non-denatured ethanol
    • –  95% denatured ethanol has toxic additives to prevent drinking (will have a health hazard logo).
    • –  100%/dehydrated/absolute/anhydrous ethanol has benzene, also toxic, from the purification process.
  • Isopropanol can be substituted for ethanol, but just takes longer to evaporate
    • –  60-70% isopropanol is just as effective as 60-70% ethanol as a disinfectant.
    • –  99-100% isopropanol (rubbing alcohol) can be purchased by the consumer as a cleaning and disinfecting agent.
  • The moisturizer can be aloe vera gel (as home recipes suggest, but hard to find) or glycerol (a common ingredient in moisturizers and makeup).
  • Lin Lab recipe: Mix two parts 95% non-denatured ethanol or 99-100% isopropanol with 1 part 90-100% glycerol.

• That’s it!
