What is Alcohol Denat.?

Alcohol Denat., short for denatured alcohol, is ethanol that has additives to make it unsuitable for drinking. Typically, it's produced by fermenting sugars and adding chemicals like methanol or isopropanol to deter consumption.

This ingredient is commonly used in personal care products for its antiseptic properties and ability to dissolve other ingredients. While it effectively evaporates quickly, leaving no residue, its impact on skin health is debated. Some research suggests it can be drying or irritating to the skin, especially in high concentrations.

Consumers should know that seeing Alcohol Denat. on a label does not necessarily imply the product is harmful; however, those with sensitive skin may want to be cautious of frequency and concentration.
