Propylene Glycol (PG) is a colorless, odorless, organic diol (a compound containing two hydroxyl groups) characterized by its highly hygroscopic nature and excellent biocompatibility. $\text{PG}$ is one of the most important liquid excipients in pharmaceutical formulations, primarily serving as a Solvent, a Vehicle for lipid-soluble or poorly water-soluble Active Pharmaceutical Ingredients (APIs), and a Humectant in topical preparations. It is a key component in oral solutions, topical preparations, and emulsified drug delivery systems.
Solvent for APIs in syrups and oral drops.
Improves the taste and solubility of the drug, and helps maintain formulation stability.
Creams, ointments, and dermal solutions.
Acts as a humectant to prevent skin dryness and a penetration enhancer to aid drug absorption through the skin.
Cosolvent for the preparation of sterile injectables.
Its stability and safety make it suitable for sterile formulations, though it must be used within specific concentration limits.
Vehicle for liquid filling of capsules.
Compatible with the gelatin shell.
The product fully complies with the requirements specified in the United States Pharmacopeia (USP), the European Pharmacopoeia (EP), and/or other relevant standards.
Strict control over product purity, focusing on the minimum content of toxic impurities such as Ethylene Glycol and Diethylene Glycol.
Accurate determination of the product's viscosity and density to ensure consistent performance as a solvent.
Production is conducted in a rigorous cGMP environment, ensuring consistency in physicochemical properties.
