Alcohol Denat. is a versatile ingredient commonly found in skincare and cosmetic products. It acts as a solvent, helping to dissolve other ingredients and enhance their absorption into the skin, making your products more effective. Additionally, it serves as a preservative, extending the shelf life of formulations and keeping them fresh for longer. While Alcohol Denat. can offer benefits like a lighter feel and quicker drying time in formulations, it's important to use it wisely. For some individuals, particularly those with sensitive or dry skin, it may cause irritation or dryness. However, when used in the right concentrations, it can provide a refreshing and clean sensation, making it a popular choice in many beauty products.
