Propylene Glycol (PG) is a ubiquitous chemical compound, integral to countless products across the pharmaceutical, food, cosmetic, and industrial sectors. Its unique combination of properties—solvency, hygroscopicity, and low toxicity—makes it an essential ingredient for formulators worldwide. As a premier chemical supplier, we are committed to providing high-purity Propylene Glycol to meet the exacting standards of our global clientele.

Understanding Propylene Glycol's Chemical Nature

Propylene Glycol, with the chemical formula C3H8O2 and CAS number 57-55-6, is a viscous, colorless, and nearly odorless liquid. It is classified as a diol due to its two hydroxyl groups. Its key properties include:

• Solubility: PG is miscible with water, acetone, and chloroform, making it an excellent solvent for a wide range of substances.
• Hygroscopicity: It readily absorbs moisture from the air, making it an effective humectant in cosmetic and food applications to prevent drying.
• Low Volatility: PG has a low vapor pressure, contributing to its stability and safety in various formulations.
• Freezing Point Depression: It effectively lowers the freezing point of water, crucial for antifreeze and coolant applications.
• Safety Profile: Generally recognized as safe (GRAS) by regulatory bodies like the FDA, especially in its USP and food grades, making it suitable for sensitive applications.

Diverse Applications Across Industries

The versatility of Propylene Glycol allows its application in numerous fields:

• Pharmaceuticals: As a USP-grade excipient and solvent, it is vital for drug delivery systems, ensuring stability and solubility of APIs in various formulations.
• Food: It functions as a humectant, stabilizer, and solvent in products ranging from baked goods and beverages to confectioneries, enhancing texture and shelf-life.
• Cosmetics: PG is a key ingredient in skincare, haircare, and oral care products, acting as a moisturizer, solvent, and emollient to improve product performance and feel.
• Industrial: Its use extends to antifreeze, de-icing fluids, heat transfer fluids, solvents for paints and coatings, and as a precursor for resins.
