Phenylbenzimidazole Sulfonic Acid

Also known as: Ensulizole

Phenylbenzimidazole Sulfonic Acid is a chemical UV filter primarily used to protect skin from UVB radiation. It works by absorbing harmful UV rays and converting them into heat, which is then released from the skin. This ingredient is water-soluble, making it suitable for lighter, non-greasy sunscreen formulations.
