The pharmaceutical industry relies on a wide array of excipients to ensure the safe and effective delivery of active pharmaceutical ingredients (APIs). Among these, Propylene Glycol (PG), specifically USP Grade 1,2-Propanediol, plays a critical role due to its unique properties. As a leading chemical supplier and manufacturer from China, we understand the stringent requirements of the pharmaceutical sector and are dedicated to providing high-purity PG that meets these exacting standards.

USP Grade Propylene Glycol is a colorless, viscous, and nearly odorless liquid that is completely miscible with water and many organic solvents. Its primary functions in pharmaceutical formulations include acting as a solvent, a humectant, a stabilizer, and a carrier. As a solvent, PG is highly effective at dissolving APIs that may have limited solubility in water. This is crucial for creating liquid dosage forms such as oral syrups, solutions for injection, and topical preparations, ensuring that the medication is readily available for absorption by the body. For pharmaceutical developers, the ability to buy high-purity 1,2-Propanediol is essential for formulating stable and bioavailable medications.

Its hygroscopic nature, the ability to attract and retain moisture, also makes PG valuable in pharmaceutical applications. In topical ointments and creams, it helps to maintain the desired consistency and prevent the product from drying out. Furthermore, PG can act as a stabilizer, preventing the crystallization of certain APIs and maintaining the overall integrity of the formulation over its shelf life. The consistent quality and purity of PG supplied by a reliable chemical manufacturer are therefore paramount.

The safety profile of USP Grade Propylene Glycol is also a significant advantage. It is recognized as safe by major regulatory bodies like the FDA for use in food, cosmetics, and pharmaceuticals. This low toxicity makes it a suitable component for both internal and external medicinal applications. When sourcing 1,2-Dihydroxypropane for your pharmaceutical research or manufacturing, selecting a supplier that can guarantee adherence to USP standards is a critical step.
