Although the formulations presented by the WHO are certainly effective in combatting the novel coronavirus, they may not be the best for your skin. Those formulations contain glycerol as a humectant to keep the alcohol from drying out your skin, but you may prefer the feel of a hand sanitizer that contains aloe Vera gel as an emollient (a substance which softens and conditions your skin).
Aloe Vera gel hand sanitizers are commercially available and used to be exceedingly common (until the novel coronavirus pandemic caused hand sanitizers across the country to go out of stock). So, if you are looking for a hand sanitizer recipe that yields a product with a more familiar feel than that of the WHO formulations, then you might want to consider the aloe Vera gel hand sanitizer recipes found in this chapter.
Also, the WHO formulations use tools and equipment that you may not have at your disposal. The graduated metric measuring cylinders and so forth necessary for the WHO
hand rubs are more commonly found in a science laboratory than in your kitchen at home. So, if all you have at home are some good old fashioned measuring cups (which probably use the United States customary units of cups, teaspoons, pints, gallons, etc.), you will probably not be able to replicate the exact measurements of the WHO formulations. In such a case, this article is your friend. Many of the formulations in this article will require far less exactitude than the WHO formulations.
The following formulations contain the steps and ingredients necessary to produce aloe Vera gel hand sanitizers with the following amounts of alcohol concentration by volume: 80 percent v/v, 75 percent v/v, 70 percent v/v, and 66.67 percent v/v. Remember that because your measurements are probably not as exact as they would be for the WHO formulations, the final product alcohol concentrations will also be less exact. For example, the recipes listed under the heading “80 Percent Aloe Vera Formulation” may be slightly less than 80 percent in terms of alcohol concentration.
