Though it is deemed safe to store at room temperature, increase in the temperature may lead to leaching of chemicals into the drink.
Can you mix water with isopropyl alcohol?
Because water molecules are polar, any liquid that does not have polar molecules—such as oil—is usually immiscible with water. Rubbing alcohol molecules have a polar and nonpolar part, which means they are able to form hydrogen bonds with water and therefore able to mix with it.
