Used primarily as a photostabilizer in sunscreen formulations and cosmetic products due to its ability to absorb ultraviolet (UV) radiation, particularly in the UVB and UVA ranges. It helps prevent degradation of active ingredients in sunscreens when exposed to sunlight, thereby enhancing product shelf life and effectiveness. Also functions as a chelating agent, improving stability of formulations by binding metal ions that could otherwise catalyze decomposition reactions. Its presence in topical products contributes to overall photoprotection by reducing UV-induced skin damage.
