Alcohol Denat.

Denatured alcohol is ethanol that has had denaturants added to make it unsuitable for drinking, typically to avoid alcohol taxes. In cosmetics, it functions as a solvent, astringent, and quick-drying agent. Like regular alcohol, it can be drying and irritating to the skin, especially in high concentrations.
