  • Description


    2-Phenylbenzimidazole-5-sulfonic acid, with the chemical formula C13H10N2O3S and CAS registry number 27503-81-7,ensulizole is one of the chemical names for phenylbenzimidazole sulfonic acid. It is a compound utilized in various applications including its role as a UV filter in sunscreens and photostabilizer in polymers, used as a sunscreen ingredient and also to protect a product from deterioration caused by uV light.. This compound, also known as PBSA, is characterized by its phenylbenzimidazole moiety with a sulfonic acid group attached at the 5-position. It is commonly employed in the cosmetics and personal care industry due to its ability to absorb UV radiation, providing protection against skin damage caused by sun exposure. Additionally, 2-Phenylbenzimidazole-5-sulfonic acid is utilized in the formulation of plastics and polymers to enhance their stability against degradation induced by UV light. Its versatile properties make it an important ingredient in various products aimed at protecting against UV-induced photodamage.

    ECHEMI Editorial Reference
    Ensulizole is a sulfonated UV absorber and can intense UVB and partial UVA absorption. Ensulizole can damage the DNA through the generation of reactive oxygen species (ROS) upon UV or sunlight irradiation. Ensulizole is a water soluble sunscreen ingredient[1].
    Ensulizole is a member of benzimidazoles.|Ensulizole, also known as 2-phenylbenzimidazole-5-sulfonic acid, is a water-soluble sunscreen agent that absorbs strongly at UV-B wavelengths. It is commonly found in cosmetic products and sunscreen formulas in combination with other UV filter compounds due to its minimal protection against UV-A wavelengths. Due to its water solubility, ensulizole is commonly used in products formulated to feel light and less oily. It was demonstrated by studies that ensulizole treatment provided protection against cyclobutane pyrimidine dimers and photosensitized the formation of oxidized guanine bases after UV-A or UV-B exposure. According to the FDA, the maximal approved concentration of ensulizole is 148 mM although concentrations ranging between 74 and 148mM can be found in commercial sunscreen products.
