This is a great idea but the resulting product does not meet the CDC recommendations for a virucide which is 60% alcohol.

To make 8 oz of hand sanitizer that has a 60% alcohol solution using 91% Isopropyl Alcohol you would need to use 2/3 cup alcohol and 1/3 cup aloe vera.

Here's the math -
2/3 cup (5.333 oz) of 91% Isopropyl Alcohol provides 4.85 oz of alcohol (the rest is water)
5.333 * 91% = 4.85
1/3 cup (2.667 oz) of aloe to make 1 cup (8 oz)
Dividing the alcohol 4.85 oz by 8 oz = 60.6%

Thanks for this comment! Watched your video and gave it a thumbs up. Great Ideas!

Math is NOT my forte - but hand sanitizer has to be 60% alcohol to be effective in killing viruses (https://www.cdc.gov/handwashing/show-me-the-science-hand-sanitizer.html) and I think this recipe ends up with less than that? And therefore isn't going to be as effective as something with 2/3 cup rubbing alcohol and 1/3 cup aloe vera - this end product is watery and harder to use - but will actually kill corona virus.

Thanks for the heads up! I accidently got the amount switched. Edited now.
