Again, this version is the same as the most straightforward version but with the addition of hydrogen peroxide.
Note: If you can follow the measurements correctly, your final product will have an actual alcohol concentration of 71.998 percent v/v. However, you most likely will not get anywhere near that exact measurement, due to the limitations of your measuring cups. Only a very finely graduated cylinder could come close to replicating that alcohol content.
Again, start by using isopropyl alcohol that is 99 percent (or higher).
Ingredients:
– 99 percent (or higher) isopropyl alcohol (also known as 99 percent rubbing alcohol)
– 100 percent pure aloe Vera gel
– 3 percent hydrogen peroxide
Other Materials:
– Plastic or glass bottle or container with a leak-proof lid or a pump cap top
– Metal or plastic funnel
– Bowl
– Wooden, metal, or plastic spoon or paddle
Proportions of Ingredients:
– You will need 3 cups of isopropyl alcohol.
– You will need 1 cup of aloe Vera gel.
– You will need eight teaspoons of hydrogen peroxide.
Step by Step Guide to Preparation
Step 1
Pour the 3 cups of 99 percent isopropyl alcohol into the bowl. Be careful not to splash or spill the alcohol, as it can be extremely harsh on your skin. If you want, you can wear gloves during this and all the other steps.
Step 2
Pour the 1 cup of 100 percent aloe Vera gel into the bowl.
Step 3
Pour the eight teaspoons of 3 percent hydrogen peroxide into the bowl.
Step 4
Stir the mixture together thoroughly using the wooden, metal, or plastic spoon or paddle.
Step 5
Using the funnel, pour the mixture from the bowl into the empty bottle or container.
Step 6
Screw on the top of the pump cap as soon as possible to prevent the alcohol from evaporating.
Step 7
Place the bottle of hand sanitizer in quarantine for 72 hours before using it. This will allow enough time for the hydrogen peroxide to take effect and kill any bacterial spores which may have been present during the mixing process or which may exist inside the bottle. After 72 hours of quarantine, your hand sanitizer is ready for use.
