Isopropyl Alcohol

Description

Isopropyl alcohol, also known as 2-propanol or rubbing alcohol, is a widely used compound in skincare and cosmetic formulations. This colorless, flammable liquid with a characteristic odor is primarily valued for its antiseptic and solvent properties. In skincare, isopropyl alcohol functions as an astringent, helping to cleanse the skin and temporarily tighten pores. It's particularly effective in removing excess oils and debris from the skin's surface, making it a common ingredient in toners and acne-fighting products.

The rapid evaporation rate of isopropyl alcohol contributes to its cooling effect when applied to the skin, which can provide temporary relief from minor skin irritations. However, its potent nature can also lead to dryness and irritation, especially for those with sensitive or already dry skin. In formulations, it's often used in lower concentrations or balanced with moisturizing ingredients to mitigate potential adverse effects.

Beyond its direct skin applications, isopropyl alcohol serves as an excellent solvent, aiding in the dissolution of other skincare ingredients and enhancing product stability. It's also utilized in the manufacturing process of many cosmetics and as a preservative to extend product shelf life.
