Brief Introduction:

2-Phenylbenzimidazole-5-Sulfonic Acid, also known as Ensulizole or UV-T, which is a sulfonated UV absorber. As a water-soluble high-efficiency UVB absorber, its UV absorption rate at about 302nm is at least 920, and it can also absorb a small part of the UVA band. Ensulizole is often used in conjunction with other ingredients such as Avobenzone, Titanium Dioxide, Zinc Oxide, Bis-ethylhexyloxyphenol Methoxyphenyl Triazine or Methylene Bis-Benzotriazolyl Tetramethylbutylphenol. When exposed to sunlight, its protective ability and quality will not gradually decrease over time.
