For businesses in the cosmetics, inks, coatings, and textile industries, sourcing high-quality UV absorbers is crucial for product performance and longevity. Among the most effective and versatile options is Disodium 2,2'-dihydroxy-4,4'-dimethoxy-5,5'-disulfobenzophenone, commonly known by its CAS number 76656-36-5 or trade names like BP-9. If you're looking to buy this essential chemical, understanding the sourcing landscape, particularly from China, is vital.

Understanding UV Absorber BP-9 (CAS 76656-36-5)

This particular UV absorber stands out due to its unique properties: it is water-soluble and exhibits excellent absorption in the UV-A and UV-B spectrum (280-320nm). This makes it ideal for a wide range of aqueous formulations where traditional oil-soluble UV absorbers would not be suitable. Its primary applications include protecting cosmetics from photodegradation, preventing color fading in inks and dyes, and enhancing the durability of coatings and textiles.

Key Factors When Sourcing from China

When seeking a reliable cas 76656-36-5 supplier China, several factors should be considered to ensure you receive a product that meets your specifications and that your supply chain is secure:

• Purity and Specifications: Always verify the product's purity. For BP-9, a minimum purity of 95% is common, with higher purities (≥99.0%) often available for more demanding applications. Ensure the supplier can provide a Certificate of Analysis (CoA) detailing key parameters like appearance, content, and loss on drying.
• Water Solubility: Confirm the product's solubility characteristics. As a water-soluble UV absorber, its performance in aqueous systems is a critical advantage.
• Application Suitability: Discuss your intended application with the supplier. A knowledgeable manufacturer will guide you on whether their specific grade of BP-9 is optimal for your cosmetic, ink, coating, or textile formulation.
• Manufacturing Standards: Inquire about the supplier's manufacturing processes and quality control measures. Reputable suppliers adhere to international standards and can provide safety data sheets (SDS) and technical data sheets (TDS).
• Pricing and MOQs: Compare the disodium 2,2′-dihydroxy-4,4′-dimethoxy-5,5′-disulfobenzophenone price from different suppliers. Understand their Minimum Order Quantities (MOQs) and packaging options (e.g., 25kg drums). Negotiating a fair price is easier when you have a clear understanding of your volume requirements.
• Logistics and Lead Times: Factor in shipping costs, delivery times, and customs procedures when evaluating suppliers. A reliable supplier will offer transparent information on logistics.
