How to make hand sanitizer with rubbing alcohol?

You’re going to need some alcohol. According to the Centers for Disease Control and Prevention, your sanitizer mix must be at least 60 percent alcohol to be effective. But it's better to get way above that—aim for a minimum of 75 percent. A bottle of 99 percent isopropyl alcohol is the best thing to use.

• Isopropyl alcohol
  
• Glycerol or glycerin 
  
• Hydrogen peroxide 
  
• Distilled water 
  
• Spray bottle

The aloe mixture gets the job done, but aloe also leaves your skin annoyingly sticky. So, here's a recipe that's less sticky and more potent, based on the mix recommended by the WHO.

Mix 12 fluid ounces of alcohol with 2 teaspoons of glycerol. You can buy jugs of glycerol online, and it's an important ingredient because it keeps the alcohol from drying out your hands. If you can't find glycerol, proceed with the rest of the recipe anyway and just remember to moisturize your hands after applying the sanitizer.
