Used primarily as an ultraviolet (UV) absorber in cosmetic formulations, especially in sunscreens and skincare products. It protects the skin by absorbing harmful UV radiation, particularly in the UVB and short UVA ranges. Also employed in plastics, coatings, and adhesives to prevent UV-induced degradation, helping to maintain material integrity and color stability when exposed to sunlight. Its ability to dissipate absorbed UV energy as heat makes it effective in extending the lifespan of products exposed to outdoor conditions.
