Used primarily as an ultraviolet (UV) absorber in cosmetic formulations, especially in sunscreens and skin care products, to protect both the product and the skin from UV degradation. It stabilizes active ingredients in lotions and creams by preventing photodecomposition. Also incorporated into plastics, coatings, and adhesives to enhance light stability and prolong material life under sunlight exposure. Its ability to absorb UV radiation makes it valuable in clear films and packaging materials where transparency and durability are required.
