1. Sunscreen Cosmetics:

As an organic UV filter, it effectively absorbs UVB rays in the 280-320nm range and some UVA rays. It is commonly used in sunscreens, sun lotions, and sun sprays. It can also stabilize the UVA sunscreen agent avobenzone, improving the sunscreen effect and stability of the formula. It is also used in cosmetics such as foundations and lipsticks to enhance product photostability.

2. Protection of Polymer Materials:

Suitable for soft and rigid polyvinyl chloride (PVC), PVC plastisols, polyesters, and acrylic glass, it acts as a light stabilizer to prevent materials from aging, yellowing, and becoming brittle due to UV irradiation, extending their service life.

3. Paints and Coatings:

Used in acrylic resins, polyurethane coatings, automotive coatings, and industrial coatings, its addition maintains coating gloss and prevents cracking, spotting, and surface peeling, improving the weather resistance of the coating. It is also suitable for water-soluble coatings.

4. Dye Industry:

Added to dyes as a light stabilizing additive, it prevents dyes from fading and decomposing under light exposure, improving the light stability and lifespan of the dyes.

5.科学研究：

Used in research on the stability and degradation of organic molecules under ultraviolet radiation, as well as in environmental chemistry studies on its persistence in aquatic ecosystems and its impact on marine organisms. It is also used in the development of new anti-UV materials.

6. Adhesives and Sealants:

Used to improve the UV resistance of adhesives and sealants, preventing them from aging due to light exposure in outdoor environments, thus maintaining their bonding strength and sealing effect.
