UV absorber UV-BP-9 also known as Uvinul DS-49,Escalol 577,PowerSorb 3048.
UV absorber UV-BP-9 is a benzophenone-based ultraviolet absorber and a water-soluble ultraviolet absorber. It can absorb ultraviolet rays ranging from 280 to 350 nanometers.
It is suitable for water-soluble cosmetics, water-based emulsions, and water-based coatings. The general usage amount is 0.5 - 2.0%.
Key Advantages and Features
- Broad UV absorption: Helps absorb UV light and reduce damage caused by sun exposure.
- Water-soluble structure: Easy to use in aqueous formulations such as water-based coatings, inks, and personal care products.
- Helps prevent discoloration: Reduces yellowing, fading, and appearance loss caused by UV exposure.
- Improves formulation stability: Supports longer product shelf life and better performance under light.
- Good compatibility: Suitable for a variety of formulation systems and can be blended into different product types.
- Clear and non-staining: Especially useful in transparent or light-colored applications where appearance matters.
- Reliable outdoor protection support: Helps maintain material quality in products exposed to sunlight for long periods.
Applications:
Used in plastics, water-based coatings and water-based cosmetics, protect the product and slow down photoaging。
