In the pharmaceutical industry, the choice of excipients is as critical as the selection of active pharmaceutical ingredients (APIs). These inactive substances play vital roles in drug formulation, delivery, and stability. Polyethylene Glycol 400 (PEG 400), a colorless, viscous liquid with CAS number 25322-68-3, has emerged as a highly valued pharmaceutical excipient due to its favorable safety profile and versatile properties. For pharmaceutical manufacturers and procurement specialists, understanding the benefits of PEG 400 and identifying reliable suppliers is key. As a dedicated pharmaceutical intermediate supplier and manufacturer in China, we are committed to providing high-quality PEG 400 for your critical applications.

PEG 400 is a water-soluble polymer that exhibits excellent solvency for a wide range of organic compounds and is virtually non-toxic. These attributes make it an ideal carrier and solvent in various pharmaceutical dosage forms, including oral liquids, capsules, ointments, and suppositories. Its low molecular weight and hydrophilic nature allow it to enhance the solubility and bioavailability of poorly water-soluble drugs, a significant challenge in modern drug development.

As a solvent in oral and topical formulations, PEG 400 facilitates the dissolution of active ingredients, ensuring uniform distribution and consistent drug delivery. Its lubricating properties are also invaluable, particularly in the manufacturing of tablets and capsules, where it helps in reducing friction and preventing sticking during the compression and coating processes, making them easier to swallow for patients. We ensure our PEG 400 meets the high purity standards required for pharmaceutical use, allowing you to buy with confidence.

In ointment and suppository bases, PEG 400’s consistency and miscibility with water and organic solvents make it an effective vehicle. It provides a smooth texture and can be formulated to achieve desired melting points and release characteristics. For pharmaceutical companies looking to buy or source these essential ingredients, partnering with a reputable PEG 400 manufacturer in China guarantees access to products that meet rigorous quality control standards and regulatory requirements.

Furthermore, PEG 400's role extends to its use in PEGylation, a process where PEG chains are attached to biomolecules to improve their therapeutic properties. While this often involves higher molecular weight PEGs, the foundational understanding of PEG’s benefits in biopharmaceuticals begins with materials like PEG 400.

When sourcing pharmaceutical excipients, reliability and quality are non-negotiable. As a trusted PEG 400 supplier, we understand the stringent demands of the pharmaceutical industry. We provide comprehensive documentation, including Certificates of Analysis, to ensure our products meet all necessary specifications. We encourage pharmaceutical professionals to request a quote and samples to experience the quality and service we offer, making us your preferred partner for essential pharmaceutical intermediates.

In conclusion, Polyethylene Glycol 400 is a cornerstone excipient in the pharmaceutical industry, offering unmatched versatility and safety. Its roles as a solvent, lubricant, and vehicle are indispensable for creating effective and stable drug formulations. Securing a reliable supply of high-quality PEG 400 from an experienced manufacturer like us is a strategic move for any pharmaceutical business focused on innovation and quality.
