At NINGBO INNO PHARMCHEM CO.,LTD., we believe in arming our partners with a deep understanding of the materials they use. Polyethylene Glycol 4000 (PEG 4000) is a complex polymer with well-defined scientific properties that make it indispensable in the pharmaceutical industry. Its classification as a pharmaceutical-grade excipient highlights the stringent quality and purity requirements it must meet.

The fundamental science behind PEG 4000 lies in its structure: a polyether derived from ethylene oxide. This structure gives it excellent water solubility, making it an ideal component for aqueous formulations. Its molecular weight, averaging around 4000 Daltons, influences its physical state – typically a white, waxy solid – and its viscosity. When manufacturers decide to buy polyethylene glycol 4000 online, they are acquiring a material with predictable physical and chemical characteristics that are crucial for formulation reproducibility.

Understanding the uses of polyethylene glycol 4000 in pharmaceuticals requires an appreciation of its functional roles. As a lubricant, it reduces friction during tablet compression. As a binder, it helps hold tablet ingredients together. Its ability to act as a humectant keeps formulations moist, and as a plasticizer, it imparts flexibility to films used in tablet coatings. These varied functions are supported by its compliance with pharmaceutical grade standards, such as those outlined in the USP, BP, and EP. A reputable polyethylene glycol 4000 supplier ensures these standards are met.

The specific identification, polyethylene glycol 4000 CAS 25322-68-3, is a key identifier for quality assurance. Manufacturers rely on this number to confirm they are obtaining the correct grade of PEG 4000. The benefits of PEG 4000 in drug formulations are intrinsically linked to these scientific properties and rigorous standards. For instance, its use as a solubilizer can significantly improve the delivery of poorly soluble drugs, a common challenge in pharmaceutical R&D.

As a leading polyethylene glycol 4000 supplier, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing materials that adhere to the highest scientific and regulatory principles. We understand that the success of pharmaceutical products hinges on the quality of their components. Therefore, we ensure our PEG 4000 is consistently pure, safe, and effective for all intended pharmaceutical applications.

For manufacturers seeking a detailed understanding of PEG 4000's scientific profile and how it can enhance their products, NINGBO INNO PHARMCHEM CO.,LTD. is ready to provide comprehensive information and support.
