Polyethylene Glycol 4000 (PEG 4000) is a well-established and highly versatile compound in the pharmaceutical industry. Ningbo Inno Pharmchem Co., Ltd. specializes in supplying pharmaceutical-grade ingredients, and PEG 4000 is a cornerstone product in our portfolio. Understanding its different grades and applications is crucial for formulators aiming to develop safe and effective medications. This guide aims to illuminate the significance of PEG 4000 in pharmaceutical manufacturing.

The pharmaceutical utility of PEG 4000 is largely attributed to its compliance with rigorous quality standards, most notably the United States Pharmacopeia (USP) and the European Pharmacopoeia (EP). These certifications ensure that PEG 4000 possesses specific purity levels, physical characteristics, and adherence to safety protocols required for medicinal use. When pharmaceutical companies look to buy PEG 4000, specifying USP or EP grade is essential for regulatory compliance and product integrity.

One of the most prominent uses of PEG 4000 is in the formulation of laxatives. As an osmotic laxative, PEG 4000 works by drawing water into the intestinal lumen, which softens stool and increases bowel motility. Its low systemic absorption and favorable safety profile make it a preferred choice for over-the-counter and prescription bowel preparation products. Sourcing high-quality PEG 4000 from a reliable supplier like Ningbo Inno Pharmchem is key to developing effective and safe laxative treatments.

Beyond its role as an active ingredient in laxatives, PEG 4000 serves as an indispensable excipient in a wide array of pharmaceutical formulations. Its properties as a binder, lubricant, plasticizer, and humectant are leveraged in the production of tablets, capsules, ointments, and suppositories. As a binder, it facilitates tablet formation; as a lubricant, it prevents sticking during compression; and as a humectant, it helps retain moisture in topical preparations. The ability to purchase PEG 4000 that seamlessly integrates into these varied dosage forms underscores its importance.

Ningbo Inno Pharmchem Co., Ltd. is committed to providing pharmaceutical manufacturers with access to high-quality PEG 4000 that meets global pharmacopeial standards. Our dedication to quality assurance ensures that every batch of PEG 4000 you buy from us supports your efforts to create safe, effective, and compliant pharmaceutical products, whether for laxative applications or as a versatile excipient.
