Polyethylene Glycol 4000 (PEG 4000) is a fascinating polymer that bridges the gap between basic chemistry and diverse industrial, pharmaceutical, and cosmetic applications. Its chemical structure, characterized by repeating ethylene oxide units, imparts unique properties such as water solubility, flexibility, and low toxicity. NINGBO INNO PHARMCHEM CO.,LTD., as a leading PEG 4000 supplier in China, provides access to this versatile compound, facilitating innovation across multiple sectors.

The chemical formula of PEG 4000, HO-(CH₂CH₂O)n-OH, where 'n' represents the average number of repeating ethylene oxide units, dictates its molecular weight and thus its physical state. With an average molecular weight of approximately 4000 g/mol, PEG 4000 typically presents as a white, waxy solid or flakes at room temperature. This solid form makes it convenient for handling and formulation in many applications. Its full solubility in water is a key attribute, arising from the ether oxygen atoms readily forming hydrogen bonds with water molecules. This property is fundamental to its utility in aqueous-based formulations.

The versatility of PEG 4000 is evident in its wide range of applications. In the pharmaceutical industry, it serves as an essential excipient. Its role as a binder and film-coating agent in tablet manufacturing contributes to dosage form integrity. As a base for ointments and suppositories, it ensures the smooth delivery of active ingredients. Furthermore, its ability to act as a solubilizer for poorly water-soluble drugs enhances the bioavailability of many therapeutic compounds. When you buy PEG 4000 from NINGBO INNO PHARMCHEM CO.,LTD., you are investing in a material critical for effective drug formulation.

In the cosmetic and personal care sectors, PEG 4000 functions as a moisturizer and emollient, improving skin feel and hydration in creams and lotions. It also acts as a thickener, contributing to desirable product textures. Its non-ionic nature and low toxicity make it a safe choice for skin and hair care products. NINGBO INNO PHARMCHEM CO.,LTD. is a reliable PEG 4000 manufacturer in China, providing the quality needed for premium cosmetic formulations.

Industrially, PEG 4000 finds use as a binder in powder formulations, a lubricant in manufacturing processes, and a component in the production of specialty resins, enhancing flexibility and durability. Its adaptability across such a broad spectrum of industries underscores its chemical utility. As a leading PEG 4000 supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing this essential chemical with consistent quality and reliable supply.

In conclusion, Polyethylene Glycol 4000 is a remarkable polymer with a unique combination of chemical properties and versatile applications.
