In the realm of material science and product formulation, safeguarding against the detrimental effects of ultraviolet (UV) radiation is a critical concern. UV absorbers play a pivotal role in this protection, and among them, Disodium 2,2'-dihydroxy-4,4'-dimethoxy-5,5'-disulfobenzophenone (CAS 76656-36-5), often abbreviated as BP-9, has gained significant traction due to its unique characteristics and broad applicability.

What is UV Absorber BP-9?

BP-9 is a highly effective organic compound belonging to the benzophenone family of UV absorbers. What sets it apart is its sulfonated structure, which imparts excellent water solubility. This characteristic makes it particularly valuable for applications in aqueous systems, a domain where many traditional UV absorbers struggle. Its chemical name, Disodium 2,2'-dihydroxy-4,4'-dimethoxy-5,5'-disulfobenzophenone, hints at its complex molecular structure designed for optimal UV absorption and dispersibility.

Key Properties and Performance

The primary function of BP-9 is to absorb harmful UV radiation and dissipate it as heat, thereby preventing the UV rays from damaging the substrate it protects. Its performance is characterized by:

  • Broad UV Absorption: BP-9 effectively absorbs UV radiation in the critical 280-320 nm range, providing robust protection against UV-B rays and contributing to defense against some UV-A rays.
  • Excellent Water Solubility: This is its most significant advantage, allowing for seamless integration into water-based formulations like cosmetics, lotions, inks, and water-based coatings.
  • High Purity: As a reputable manufacturer, we ensure our BP-9 (CAS 76656-36-5) meets high purity standards (often ≥99.0%), guaranteeing consistent performance and minimizing potential side reactions in complex formulations.
  • Stabilization Effects: It helps to preserve the color, fragrance, and physical properties of products by preventing UV-induced degradation.

Diverse Applications Across Industries

The unique properties of BP-9 lend themselves to a wide array of applications:

  • Cosmetics and Personal Care: It's a preferred ingredient for protecting sunscreens, lotions, hair care products, and makeup from UV damage, ensuring product stability and efficacy. When you buy uv absorber bp-9 for cosmetics, you are investing in product longevity.
  • Inks and Coatings: BP-9 is an excellent choice for water-based inks and coatings, preventing color fading and enhancing the durability of printed materials and protective finishes. It is a sought-after high purity uv absorber for inks.
  • Textiles: It can be applied during textile finishing processes to protect fabrics from fading and fiber degradation when exposed to sunlight.
  • Other Water-Based Formulations: Its versatility extends to various other aqueous systems requiring UV protection.

Buying Guide: Sourcing BP-9 from China

When looking to purchase UV Absorber BP-9, particularly from a China supplier, consider these points:

  • Verify Purity and Specifications: Ensure the supplier provides detailed technical data sheets and certificates of analysis.
  • Check Application Suitability: Confirm the grade is appropriate for your intended use.
  • Inquire About Pricing: Compare the disodium 2,2′-dihydroxy-4,4′-dimethoxy-5,5′-disulfobenzophenone price from different reputable manufacturers.
  • Logistics and Support: A reliable manufacturer will offer clear logistics and responsive customer service.
