Used primarily as a UV absorber in cosmetic formulations and sunscreens due to its strong ability to absorb ultraviolet radiation, especially in the UVA range. It provides photostability to formulations and protects both the product and skin from UV-induced damage. Commonly found in high-SPF skincare and makeup products where long-term stability and broad-spectrum protection are required. Also used in polymer systems to prevent UV degradation, extending the lifespan of materials exposed to sunlight.
