For procurement professionals in the chemical, pharmaceutical, and cosmetic industries, securing a reliable source of high-purity Polyethylene Glycol 400 (PEG 400) is a critical task. This ubiquitous chemical, known for its versatility and excellent safety profile, is a foundational component in a vast array of products. Understanding the key specifications and supplier capabilities will ensure you make informed purchasing decisions. This guide is designed to help you navigate the process of sourcing PEG 400, focusing on purity, applications, and the advantages of partnering with a reputable manufacturer.

PEG 400, identified by its CAS number 25322-68-3, is characterized by its clear, colorless liquid appearance and its extensive solubility in water and many organic solvents. Its primary appeal lies in its low toxicity and its ability to act as a solvent, humectant, lubricant, and plasticizer. For procurement managers aiming to buy Polyethylene Glycol 400 in China, quality assurance is paramount. Look for suppliers who provide detailed certificates of analysis (CoA) that confirm purity levels, typically exceeding 99%, along with low moisture content and adherence to international standards like USP or EP if required for pharmaceutical applications.

The applications of PEG 400 are incredibly diverse, necessitating a keen understanding of its role in different sectors. In the cosmetic industry, it's a favored ingredient for lotions, creams, and bath gels due to its moisturizing and emollient properties. Pharmaceutical companies rely on it as a solvent and base for various dosage forms, including ointments and suppositories, making a high-purity grade essential. For those in industrial sectors, PEG 400 serves as a crucial component in inks, adhesives, and as a lubricant. When specifying your needs, clearly defining the intended application—whether for cosmetic use, pharmaceutical applications, or industrial grade needs—will help you pinpoint the right product and supplier.

When evaluating potential suppliers, consider their production capacity, their ability to provide consistent quality, and their logistical capabilities. A strong PEG 400 supplier will offer competitive pricing, particularly for bulk orders, and possess robust quality control measures.
