Polyethylene Glycol 4000 (PEG 4000) stands out as a vital excipient in the pharmaceutical industry, contributing significantly to the efficacy, stability, and patient compliance of various drug formulations. As a leading pharmaceutical excipient supplier, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical role PEG 4000 plays and is committed to providing high-quality material for your drug development needs.

PEG 4000: A Multifunctional Excipient

PEG 4000, a water-soluble polymer, offers a unique combination of properties that make it indispensable in pharmaceutical manufacturing. Its applications include:

  • Lubricant and Binder: In solid dosage forms like tablets and capsules, PEG 4000 acts as an effective lubricant, reducing friction during manufacturing processes and ensuring smooth tablet ejection. It also functions as a binder, promoting granule formation and tablet integrity.
  • Ointment and Suppository Base: Its semi-solid nature at room temperature and its compatibility with various active pharmaceutical ingredients (APIs) make it an excellent base for topical preparations and suppositories, ensuring controlled release and stability.
  • Solubilizer and Stabilizer: PEG 4000 can improve the solubility of poorly water-soluble drugs, enhancing their bioavailability. It also acts as a stabilizer in liquid formulations, preventing degradation and ensuring a longer shelf life.
  • Drug Delivery Systems: Increasingly, PEG 4000 is incorporated into advanced drug delivery systems, including nanoparticles and hydrogels, to improve drug targeting, sustained release, and reduce immunogenicity.

Ensuring Quality for Pharmaceutical Applications

The pharmaceutical industry demands the highest standards for its raw materials. Sourcing PEG 4000 from a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures that the product meets rigorous quality specifications, including adherence to pharmacopoeial standards (USP/NF, EP, BP, JP). This commitment guarantees:

  • High Purity: Minimizing impurities such as ethylene oxide and dioxane is crucial for patient safety.
  • Consistent Molecular Weight: Uniformity in molecular weight ensures predictable physical properties and performance in formulations.
  • Batch-to-Batch Consistency: Reliable manufacturing processes guarantee reproducible results in your drug production.
