Hey mate!!!
➡️Because of alcohols nature of vaporizing at room temperature. Basically, when you sweat normally, it is to reduce the heat of your body. Sweat is a liquid, and liquids are much more effective in transferring heat than air, but sweat also takes a long time to vaporize(in which case it’s actually more effective when the droplets roll off of your body). In very simple terms, alcohol (liquid) vaporizes much faster than sweat and therefore also dissipates a lot of heat, therefore making your skin feel cold.

Acetone,petrol and perfume are volatile substance that gets evaporated when they come in contact with air Evaporation is facilitated as it uses energy from the palm hence leaving a cooling effect on our palms.
