Water-soluble UVB absorber Phenylbenzimidazole Sulfonic Acid PBSA Ensulizole CAS

Product Specification

For plastics/coatings Water-based sunscreen PBSA Ethylhexyl Methoxycinnamate

Product Introduction:

Phenylbenzimidazole sulfonic acid possesses a series of unique chemical properties. Firstly, it is a water-soluble chemical sunscreen agent that can effectively dissolve in water and organic solvents such as ethanol and isopropanol, but is insoluble in mineral oil and certain ester solvents. This characteristic makes phenyl benzimidazole sulfonic acid Chemicalbook have good compatibility and stability in cosmetic formulations. Secondly, it can demonstrate a strong absorption capacity under ultraviolet light irradiation, especially in the UVB band, with an absorption coefficient as high as 920-990, showing a stronger ultraviolet protection effect than ordinary absorbers.

As an ultraviolet absorber, it is used to protect polymer materials such as polyester, polyvinyl chloride, polystyrene and plexiglass from aging and yellowing due to light exposure.
