For procurement managers and R&D scientists in the chemical, cosmetic, and pharmaceutical industries, sourcing high-quality raw materials is critical. Benzophenone-4 (CAS 4065-45-6), a widely used UV filter, demands careful consideration when selecting a supplier. This guide aims to provide essential information for buyers seeking to purchase Benzophenone-4, focusing on its key attributes and what to look for in a manufacturing partner.

Understanding Benzophenone-4: Properties and Functions

Benzophenone-4 is recognized for its effectiveness as a water-soluble UV absorber, offering protection against both UVA and UVB radiation. Its chemical name, 5-Benzoyl-4-hydroxy-2-methoxybenzenesulfonic acid, and CAS number 4065-45-6, are crucial identifiers for procurement. Typically appearing as a white or light-yellow crystalline powder, it boasts a high assay (often 99.0% min.) and good stability. Its primary function is to prevent photodegradation in cosmetic and personal care products, thereby extending shelf life and maintaining product efficacy. For manufacturers, this means a reliable ingredient that contributes to the overall quality and performance of their end products. Understanding these specifications is vital when comparing prices and product quality from different suppliers.

Key Applications and Market Demand

The demand for Benzophenone-4 is driven by its extensive use in various sectors. In the personal care industry, it's a key ingredient in sunscreens, lotions, creams, and hair care products. Its role extends to protecting colorants and fragrances from UV-induced fading. Beyond cosmetics, it finds application as a UV absorber in water-soluble inks, paints, and as a UV stabilizer for plastics and coatings. This broad applicability makes it a consistently sought-after chemical intermediate. Procurement managers should note its widespread use, ensuring their chosen manufacturer can meet potential volume requirements. When looking to buy Benzophenone-4, considering its role in diverse end-products helps in assessing market trends.

Choosing the Right Manufacturer and Supplier

Selecting the right manufacturer for Benzophenone-4 is paramount. Look for suppliers who can provide comprehensive documentation, including Certificates of Analysis (CoA) and Safety Data Sheets (SDS), confirming product purity and safety compliance. As a buyer, understanding the manufacturing process, such as the sulfonation of Benzophenone-3, can offer insight into product quality. Reliability in supply chain management is also key. Partnering with a manufacturer that offers competitive pricing, flexible MOQs (Minimum Order Quantities), and efficient logistics ensures a smooth procurement process. NINGBO INNO PHARMCHEM CO.,LTD. positions itself as a dependable source, offering both quality and competitive pricing for bulk purchases. Engaging with such suppliers early in the product development cycle can secure favorable terms and a consistent supply.

Navigating Regulations and Safety

Compliance with regulatory standards is non-negotiable. Benzophenone-4 has specific allowed usage levels in different regions, such as the USA, Brazil, Japan, and the EU, which buyers must be aware of. While generally considered safe for its intended use, understanding its potential for skin irritation, as documented in various studies, is important. Manufacturers committed to transparency will provide detailed safety information. Buyers should prioritize suppliers who adhere to international quality standards and can provide necessary regulatory documentation, ensuring their final products meet global market requirements. The OEHHA Prop 65 warning in California, related to the production of Benzophenone-4, also highlights the importance of understanding chemical sourcing.

Conclusion
