1. Personal Care Products (Sunscreen)

功能 As a chemical UV filter, it absorbs UVB and some short-wave UVA radiation from sunlight, and is applied to the skin surface to help prevent long-term UV damage.

请注意： Relevant research literature also focuses on its residue in the environment and its ecological impact.

2. Polymers and Materials Science

功能 As a light stabilizer or UV absorber, it is added to polymers such as plastics and coatings to prevent photo-aging degradation such as yellowing and embrittlement of materials under sunlight.

Applicable materials: Suitable for various systems including polyvinyl chloride (PVC), ABS resin, acrylic resin, polyurethane, melamine resin, cellulose resin, and paints.

特点 It strongly absorbs ultraviolet light with a wavelength of 330-370 nanometers, but may cause the product to be slightly yellow due to the absorption of some visible light. A typical addition amount is 0.25% to 3%.

3. Scientific Research and Analytical Testing

Analytical Standards: Provides high-purity standard substances for quantitative analysis, method development, and quality control in instrumental analysis (such as gas chromatography and liquid chromatography).

Environmental and Toxicological Research: As a target analyte, it is used to study its distribution, migration, transformation, and potential ecological and health risks in the environment (such as water and soil) and biological samples (such as blood).
