Ensuring the safety and efficacy of cosmetic ingredients is paramount, and Phenylbenzimidazole Sulfonic Acid (CAS 27503-81-7), widely known as Ensulizole, has earned global recognition for its role as a UV filter. NINGBO INNO PHARMCHEM CO.,LTD. provides this ingredient, adhering to international standards and regulations.

Phenylbenzimidazole Sulfonic Acid is approved for use in sunscreens and cosmetic products in major markets around the world.

Similarly, in the European Union, it is widely accepted and regulated, with permitted usage levels often reaching up to 8%, reflecting a high degree of confidence in its safety and efficacy.

Beyond these major regions, Phenylbenzimidazole Sulfonic Acid is also approved in many other countries, including those in Asia and Latin America, often with similar concentration guidelines. This widespread acceptance underscores its robust safety profile and its proven ability to provide effective UV-B protection.
