is it true that ethanol on skin feels cold due to the evaporation of the alcohol

yes. But any solvent with a decent vapor pressure will do the same thing. Even water but you may need to wave your hands in the air to help it a little. That's why humans perspire; that is, they get hot, the body needs cooling, we perspire, the sweat evaporates, the body cools. Back to normal T.
