    it won’t make any difference: denatured alcohol is almost entirely ethanol, with a small percentage of adulterants added to make it undrinkable

    Denatured alcohol is just another term for “ethanol + poison”. To get non-denatured ethanol, you will likely need to buy ethanol that is safe to drink. There is nearly zero difference chemically between most (not all) denatured alcohols and drinkable ethanol.

    Most people do not understand that there are about 100 different formulas for the ingredient called “denatured alcohol”. Some of the poisons added can be really bad for you, so make sure that you use a safe grade. List of denaturants authorized for denatured spirits   and https://en.wikipedia.org/wiki/Denatured_alcohol#Formulations 

    IPA, on the other hand, is a different chemical from Ethanol. It will NOT behave the same way, the solubilities are different, etc. This may or may not be significant in your formula - the only way to know for sure is to try it.

    Thanx @Bobzchemist

    List of denatured spirit is you provided helps  to solve the problem.

    I tried IPA but according to me, the drying rate of IPA was less than ethanol.
