物理形态与操作说明

• >300, decomposes at 410
• Soluble
• Ensulizole is a selective UV-B filter with little activity against UV-A wavelengths. _In vitro_, ensulizole oxidizes guanine bases upon photoexcitation by UV-B and may cause photodamage on DNA, proteins and lipids in the cellular context.

数据库记载的用途

• Cosmetics -> Uv filter; Uv absorber
• Information on 7 consumer products that contain Phenylbenzimidazole sulfonic acid in the following categories is provided:
• 1H-Benzimidazole-6-sulfonic acid, 2-phenyl-: ACTIVE
• Indicated to be used as an UV-B-absorbing molecule in sunscreen formulations.
• A 2025 review by authors in the U.S. and U.K. used experimentally determined values of 4% for oral absorption in rats and 0.26% for dermal absorption in humans for their risk calculation purposes. Also, the authors noted no evidence of bioaccumulation in rat vivo studies, which they stated is consistent with the high water solubility and low octanol/water partition coefficient.
• Ensulizole strongly absorbs UV-B wavelengths. It offers protection against UV-B-induced cyclobutane pyrimidine dimers. Based on the findings in vitro and in cellulo, ensulizole induces damage on the DNA, causes DNA strand breaks and photosensitizes the formation of oxidized guanines via type I and II photosensitization mechanisms following UV-A or UV-B irradiation. Ensulizole is capable of generating reactive oxygen species, including singlet oxygen upon photoexcitation.
