Rubbing alcohol evaporates so quickly on skin because your skin is pretty warm and rubbing alcohol has a higher vapor pressure (and lower boiling point) compared to water. It is known as a volatile solvent because it evaporates easily.

Is evaporating rubbing alcohol on skin endothermic?
Water evaporation is an endothermic process.
What is mixed with alcohol to disinfect?

How does alchol work on your skin to male you feel cool?
Your skin warms the alcohol and it evaporates. To evaporate, a liquid needs extra energy to turn the liquid into a gas. This is called latent heat of evaporation. The only source of this latent heat is your skin, so evaporation takes heat out of the skin. This is just how sweating cools you down but alcohol has a lower boiling point than the water in sweat and so evaporation takes place more quickly with the alcohol. If you try to cool a patient with a fever, use a cloth soaked in warm water (not cold) as it will evaporate more quickly and so cool more effectively.
Why is rubbing alcohol cooler on your skin than water?
because it evapurates on the skin faster and it cools down
How is rubbing alcohol and vinegar different?

Are hand sanitizers containing rubbing alcohol toxic to the human body?
Applying rubbing alcohol to the skin is not toxic or dangerous. Rubbing alcohol however should under no circumstances be drunk.
Why does rubbing alcohol have a cooling effect on the skin?
Because alcohol evaporates at a low temperature, and an evaporating liquid absorbs heat from its surroundings without getting hotter itself in order to gain energy to evaporate, a phenomenon known as latent heat of evaporation.

Why is a child with a high fever given a sponge bath with water mixed with rubbing alcohol?
To help cool the child down. The evaporating alcohol would help with the cooling. To evaporate the alcohol needs some energy and it would take heat from the child's skin thus helping with the cooling. The water would remove heat from the skin by evaporation and conduction.
