DIY Hand Sanitizer According to CDC Specifications.

CDC says you need at least an alcohol content of 60% to make your own hand sanitizer. Using this number and a lot of research, this is the best formula I've found. Of course, you can use the CDC's recipe...it you want about 2 1/2 GALLONS of sanitizer. But if you don't want that much....

Yes, it's best to use soap and a lot of water and friction (and time scrubbing). But if you're not around a soap, sink and water and/or want the alcohol to stick to your hands a little longer, a hand sanitizer is probably a good idea.

Using 71% isopropyl alcohol

• 11 parts 71% isopropyl alcohol.
  
• 1 part 3% hydrogen peroxide.
  
• 1 part aloe or glycerin
  

11/13 = 84.6% x 71% = 60% total alcohol content

Using 91% isopropyl alcohol

• 6 parts 91% isopropyl alcohol.
  
• 2 parts 3% hydrogen peroxide.
  
• 1 part aloe or glycerin
  

6/9 parts alcohol = 66.7% x 91% = 60.7% total alcohol content

I'd probably add just another little bit more alcohol just to be sure. But you don't' want too much either because it seems that the alcohol works better at around 60-70% and not higher because the extra water helps it attact the virus more effectively by covering it more thoroughly.
