Phenyl Benzimidazole Sulphonic Acid is a common sunscreen agent. It has been approved by the US FDA to be used on suncreen labels in the United States.It is primarily a UVB protecting agent providing only minimal UVA protection.For better UV A protection, it must be paired with Avobenzone etc. Because of Pheylbenzimidazole sulphonic acid is water soluable, it has the characteristic of feeling ligter on skin. As such, it is often used in sunscreen lotions or moisturizers whose aesthetic goal is a non-greasy finish.The free acid is poorly soluble in water, so it is used as its soluble salts.
