Alcohol Denat, also known as denatured alcohol, is a common ingredient in skincare and cosmetic products. It is a type of alcohol that has been treated to make it undrinkable, often by adding chemicals or bittering agents. In beauty products, it is used as a solvent, helping other ingredients to penetrate the skin more effectively. It also acts as a preservative and can give products a quick-drying finish.
Despite its usefulness in product formulations, Alcohol Denat has garnered some controversy due to its potential to cause dryness and irritation, especially for those with sensitive skin. High concentrations of denatured alcohol can strip the skin of its natural oils, leading to dryness and potential disruption of the skin barrier.
When included in skincare products, it's important to consider your skin type and the concentration of Alcohol Denat in the formula. For individuals with dry or sensitive skin, it may be best to avoid products containing high amounts of this ingredient.
