AakoSun PBSA is better known as Phenylbenzimidazole Sulfonic Acid. It is a water-soluble sun filter that offers protection against UV-B and short range UV-A radiation. The free acid is poorly soluble in water, so it is only used as it’s soluble salts. When combined with oil-soluble UV filters such as AakoSun AVB, AakoSun TiO2 or AakoSun ZnO it offers much better protection against UV-A rays, which is a significant cause of skin cancer.
Approved for the use in sun care preparations in many countries worldwide.
