The selection of UV filters is a critical decision in the development of effective and appealing cosmetic products. Formulators are constantly seeking ingredients that offer robust UV protection, excellent stability, and desirable application properties. 2-Phenylbenzimidazole-5-sulfonic acid (CAS 27503-81-7), often referred to as Ensulizole or UV-T, has emerged as a significant player in this arena due to its unique characteristics. As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides in-depth insights into why this ingredient is a valuable asset for cosmetic innovation.

Chemical Profile and Mechanism of Action

2-Phenylbenzimidazole-5-sulfonic acid is a water-soluble organic compound belonging to the benzimidazole class. Its molecular structure is C13H10N2O3S, with a molecular weight of approximately 274.30 g/mol. The key function of this molecule is its potent absorption of UV-B radiation, typically in the wavelength range of 290-320 nm. Upon absorbing UV photons, it transitions to an excited state and then dissipates this energy harmlessly as heat, preventing the radiation from reaching and damaging the skin or other formulation components. Its chemical stability and absorption spectrum make it an effective UV-B filter.

Key Advantages for Formulators

When you buy 2-Phenylbenzimidazole-5-sulfonic acid from NINGBO INNO PHARMCHEM CO.,LTD., you benefit from its several formulation advantages:

  • Water Solubility: This characteristic is a significant differentiator, allowing for its seamless incorporation into the aqueous phase of cosmetic formulations. This facilitates the creation of light, non-greasy textures, clear gels, and sprays.
