These liquids usually have a low boiling point. Which means they evaporate easily. When they evaporate, they require energy. The heat energy provided by your skin is their latent heat of evaporation (or the energy needed to change from liquid to gas)...

Those liquids which evaporate easily at room temperature do so by absorbing the heat from the body. Most of the organic solvents like spirit, acetone etc. have high evaporation rates. even water if exposed to a draft of air evaporates more and cools the skin. The desert coolers work on this principle only.

It evaporates rapidly

because these things take the temperature of your body so that they can evaporate, that is why you feel cold.
