Bisdisulizole disodium, also known as disodium phenyl dibenzimidazole tetrasulfonate, is a water-soluble organic compound used as a broad-spectrum UV filter in sunscreens. It primarily absorbs UVB and short UVA rays, helping to protect the skin from sunburn, photoaging, and DNA damage. Commonly found in European and Asian sunscreens, it is valued for its photostability and compatibility with other UV filters.
