Widely used as a UV absorber in cosmetic formulations, especially in sunscreens, to protect the skin from harmful ultraviolet radiation. It stabilizes the product by preventing UV-induced degradation of other ingredients. Commonly found in lotions, creams, and makeup due to its ability to absorb UV light in the 300–400 nm range. Also used in plastics and coatings to enhance light stability and prolong material life under sunlight exposure.
