Used primarily as a UV absorber in cosmetic formulations and skincare products. Provides protection against ultraviolet radiation by absorbing UVB and some UVA rays, enhancing the photostability of active ingredients. Commonly found in sunscreens, lotions, and creams to prevent degradation caused by sunlight exposure. Also serves as an antioxidant, helping to reduce oxidative stress in formulations, thereby extending shelf life. Its ability to stabilize other components makes it valuable in products containing light-sensitive actives like retinoids or vitamin C.
