Propylene Glycol (PG), scientifically known as propane-1,2-diol (CAS 57-55-6), is a fundamental chemical compound with a wide array of applications across numerous industries. Its unique molecular structure and physical properties make it an indispensable ingredient in everything from pharmaceuticals and cosmetics to food products and industrial coolants. As a leading chemical supplier, we offer high-quality Propylene Glycol, ensuring its availability for diverse industrial needs.

Chemically, Propylene Glycol is an organic compound belonging to the diol family, characterized by the presence of two hydroxyl (-OH) groups. Its molecular formula is C3H8O2. This structure imparts distinct properties, including high polarity and hygroscopicity, meaning it readily attracts and holds water molecules. This makes it an excellent humectant, a property highly valued in skincare and food preservation.

The physical appearance of Propylene Glycol is that of a colorless, viscous, and nearly odorless liquid. Its miscibility with water, alcohols, and many organic solvents is a key advantage, allowing it to be easily incorporated into various formulations. Its low volatility and high boiling point (around 188 °C) contribute to its stability and usefulness in applications requiring consistent performance under varying temperatures.

One of the most significant attributes of Propylene Glycol is its low toxicity. Unlike ethylene glycol, another common glycol, PG is recognized as safe for ingestion and topical application when used within appropriate limits. This safety profile underpins its widespread use in food products (as a solvent and humectant), pharmaceuticals (as an excipient and solvent), and cosmetics (as a moisturizing agent). For companies looking to buy Propylene Glycol, its safety record is a major draw.

Industrially, Propylene Glycol finds extensive use as a component in antifreeze and de-icing fluids due to its excellent freeze-point depression capabilities. It is also used in the production of unsaturated polyester resins, polyurethanes, and as a solvent in various industrial processes. The demand for reliable suppliers of industrial-grade Propylene Glycol is consistently high, driven by its performance and cost-effectiveness.

As a trusted manufacturer and supplier, we are committed to providing Propylene Glycol that meets the highest purity standards. Whether you require USP grade for pharmaceutical applications, Food Grade for consumables, or technical grade for industrial uses, we can meet your needs.
