Widely used in cosmetic and personal care formulations as a water-soluble UV filter. Provides protection against ultraviolet radiation, particularly in the UVB range, helping prevent sun-induced skin damage. Commonly found in sunscreens, moisturizers, lip balms, and hair care products due to its ability to enhance photostability and extend product shelf life. Its sulfonic acid group allows for easy incorporation into aqueous systems, making it suitable for sprays, gels, and lotions. Exhibits good compatibility with other ingredients and offers enhanced safety profile compared to some oil-soluble UV filters.
