Polyethylene Glycol 400 (PEG 400) is a fascinating chemical compound, the utility of which stems directly from its unique molecular structure and resulting physical properties. As a polyether compound derived from petroleum, its chemical formula is commonly represented as H−(O−CH2−CH2)n−OH, where 'n' averages around 9 for PEG 400, giving it an average molecular weight of approximately 400 daltons. This structure imparts excellent water solubility and compatibility with a wide range of organic solvents, making it an exceptionally versatile ingredient across numerous sectors. For businesses looking to buy Polyethylene Glycol 400, understanding these core chemical attributes is the first step to leveraging its full potential.

The primary benefit of PEG 400 lies in its role as a solvent. Its polarity and ability to form hydrogen bonds allow it to dissolve a wide array of substances, from polar compounds to some less polar ones. This makes it an ideal carrier for active ingredients in pharmaceutical formulations, improving drug delivery and efficacy. In the cosmetic industry, it acts as a humectant, drawing moisture from the environment to hydrate the skin, and as an emollient, providing a smooth texture to creams and lotions. The reliability of a high-purity PEG 400 manufacturer ensures that these critical functions are performed effectively and safely in your end products.

Beyond solvency and moisturizing, PEG 400 offers significant advantages as a lubricant and plasticizer. In industrial applications, its lubricating properties reduce friction, making it useful in textile processing and as a mold release agent in rubber and plastic manufacturing. As a plasticizer, it increases the flexibility and workability of polymers. Its relatively low volatility and high boiling point also contribute to its stability in various formulations. For procurement managers, understanding these performance benefits helps justify the price and the importance of sourcing from a reputable supplier.

The safety profile of PEG 400, generally considered to be low toxicity, further enhances its appeal. While it is used in many consumer products, including some food applications (often under the E number E1521), its primary value proposition for B2B clients lies in its performance as a chemical intermediate. Whether you are in the pharmaceutical, cosmetic, or industrial manufacturing sector, ensuring you source from a reliable PEG 400 supplier in China can provide a competitive edge through quality and cost-effectiveness.
