Aspiration into lungs can produce severe lung damage and is a medical emergency. The freezing points are reduced until glycerine concentration is 66.7 % (mass). That means that glycerol would have the same effect as salt. Methanol, ethanol, and isopropanol boil at 65C (149F), 78C (172F), and 83C (181F), all less than the boiling point of water, and they all evaporate more easily than water. Other symptoms are expected to parallel inhalation. Water molecules easily form hydrogen bonds with one another, which creates a tangled network of attraction within the liquid. The order of the liquids from heaviest to lightest will be syrup, glycerin, water, oil, and then alcohol will be on top. The heat in that water results in some molecules moving fast enough to escape into the air, that is, evaporate.
