Residue left behind is not the alcohol but impurities dissolved in or mixed with the alcohol so pure isopropyl will not leave residue. The reason it is able to evaporate below its boiling point is the same reason that all other liquids can evaporate below their boiling points.
Does isopropyl alcohol leave behind residue?
99% isopropyl alcohol has the benefit of being non-corrosive to metals or plastics, so it can be used widely, on all surfaces, and won’t leave smears, even on glass or screens. As an industrial cleaner because it does not leave a residue that may cause complications in manufacturing.

What is the difference between rubbing alcohol and isopropyl alcohol?

Is isopropyl alcohol a contact cleaner?

Is isopropyl alcohol absorbed through the skin?
Isopropyl alcohol-containing hand rubs are widely used in healthcare for hand decontamination. … We confirmed that isopropyl alcohol could be absorbed through the intact skin of adult humans.
What temperature does isopropyl alcohol evaporate?
At 100 °C it is 100% of standard atmospheric pressure, which is why this is its boiling point. However it still evaporates at 25 °C if the air is not saturated. In any solvent mixtures, both components give off vapor and therefore evaporate.
How long does it take for 91 isopropyl alcohol to evaporate?
How long should I wait for isopropyl alcohol to dry? Alcohol has a low boiling point and thus evaporates much more rapidly than water. If its a thin enough film of moisture you can literally watch it vanish in just a few seconds. It shouldn’t take more than a minute or two at the most.
