In the pharmaceutical industry, the efficacy and safety of a drug depend not only on its active ingredient but also on the excipients used in its formulation. Propylene Glycol (PG), also known as 1,2-propanediol (CAS 57-55-6), is a cornerstone excipient, valued for its exceptional properties as a solvent, co-solvent, and stabilizer. As a dedicated supplier of pharmaceutical-grade chemicals, we are committed to providing high-purity Propylene Glycol to meet the stringent demands of this sector.

Propylene Glycol is a colorless, viscous liquid with minimal odor and taste, making it an ideal carrier for various pharmaceutical preparations. Its excellent solubility profile allows it to dissolve a wide range of active pharmaceutical ingredients (APIs) that are poorly soluble in water. This capability is critical for developing liquid oral dosage forms, injectable solutions, and topical preparations, ensuring that the API is delivered effectively to the patient. For pharmaceutical manufacturers, finding a reliable supplier of USP-grade Propylene Glycol is essential for product consistency and regulatory compliance.

Beyond its role as a solvent, PG also acts as a humectant, helping to maintain the moisture content in pharmaceutical products. This is particularly important for creams, ointments, and certain oral medications, preventing them from drying out and maintaining their intended physical properties. Furthermore, its low volatility and high boiling point contribute to the stability of formulations, protecting sensitive APIs from degradation. When you need to buy Propylene Glycol for pharmaceutical use, quality and purity are non-negotiable.

The safety of Propylene Glycol in pharmaceutical applications is well-established. It is approved by regulatory agencies like the US FDA and the European Medicines Agency for use in various drug formulations. While generally recognized as safe (GRAS), particularly in food applications, its use in pharmaceuticals is subject to strict quality controls and adherence to pharmacopoeial standards (e.g., USP, EP, BP). This ensures that the PG used in medications is free from harmful impurities and meets precise specifications.
