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.

What is the difference between Alcohol and Alcohol Denat.?
Alcohol Denat. is ethanol (alcohol) that has been mixed with other substances (denaturants) to make it unpalatable for consumption. This is often done for tax purposes, but its cosmetic functions are similar to regular alcohol.
Is Alcohol Denat. bad for sensitive skin?
For sensitive skin, Alcohol Denat. can be particularly problematic as it can cause dryness, redness, and irritation due to its solvent and astringent properties, especially when present in high amounts.
