Used primarily as a UV absorber in cosmetic formulations, especially in sunscreens and skincare products. Its ability to absorb ultraviolet radiation helps protect both the product and the skin from UV-induced damage. It stabilizes active ingredients in formulations by preventing photodegradation, extending shelf life. Commonly found in lotions, creams, and lip products where long-term exposure to light and sunlight is expected. Also used in some plastics and coatings to enhance light stability, though its main application remains in personal care products.
