This results in a faster and more thorough dissolution of the polyvinyl alcohol in the solvent.

How many ounces of 15 percent percent alcohol must be mixed with 23 percent alcohol solution to make 100 ounces?
Let x be the ounces of 15% alcohol solution. The amount of alcohol in the 15% solution is 0.15x, and the amount of alcohol in the 23% solution is 0.23(100 - x). Setting up the equation 0.15x + 0.23(100 - x) = 0.15(100) solves for x, which is approximately 38.5 ounces of the 15% alcohol solution needed.

How do you distill hand sanitizer in order to make edible alcohol?
Wikipedia has an article on Alcohol Rubs here: http://en.wikipedia.org/wiki/Hand_sanitizer They typically use ethanol (standard drinking alcohol mixed with something to render it undrinkable) or isopropanol ("rubbing alcohol" which is poisonous — not in a good way — if swallowed). A concentration of 60-70 percent is needed. Standard rubbing alcohol should do the trick, as would a 120+ proof liquor, although both will dry out your skin. You could mix in a small amount of glycerine for moisturizing, and possibly a thickener, but you risk diluting the alcohol to where the mixture is no longer effective. A mixture of nine parts 70% rubbing alcohol to one part glycerine should give you a good (but runny) substitute at a lower price.
