biological activity | Ensulizole (PBSA) is a water-soluble sunscreen component, a sulfonated UV absorber, which is characterized by strong absorption of UVB and partial absorption of UVA. Ensulizole can destroy DNA by the generation of reactive oxygen species (ROS) under ultraviolet light or sunlight. |
