• Features and Applications:
  It is an oil-soluble UVA sunscreen agent that effectively absorbs ultraviolet rays in the 320–400 nm range, with an absorption peak at 354 nm—making it one of the most efficient UV absorbers for the UVA band.

  • It exhibits excellent photostability and can completely replace avobenzone (a common UVA absorber with relatively lower photostability).
  • It has good compatibility with other sunscreen agents and cosmetic raw materials.
  • Typical applications include cosmetics, sunscreens, and light filters. The general recommended dosage is 0.2–0.5%, while the maximum allowable dosage in the European Union is 10%.

• Packaging: Usually 25 kg fiber drum.

• Storage Conditions: Store in a dry and cool place, keep sealed. The shelf life is 2 years when stored properly.
