Propylene Glycol (PG), chemically known as propane-1,2-diol, is a synthetic organic compound with a unique set of properties that make it incredibly versatile across a broad spectrum of industries. As a chemical supplier, we recognize the significant role PG plays in formulations ranging from food and pharmaceuticals to industrial fluids. Understanding its chemical characteristics is key to appreciating its widespread application and ensuring its effective use.

At its core, Propylene Glycol is a diol, meaning it contains two hydroxyl (-OH) groups. This structure imparts excellent solvency and hygroscopic (moisture-attracting) properties. It is a viscous, colorless liquid that is nearly odorless and has a faintly sweet taste, which are advantageous for its use in consumer products. PG is miscible with a wide array of solvents, including water, acetone, and chloroform, but is insoluble in oil. Its low vapor pressure and low toxicity further contribute to its desirability.

The applications of Propylene Glycol are extensive. In the food industry, it functions as a humectant, emulsifier, stabilizer, and solvent for flavors and colors. Its ability to retain moisture makes baked goods and confectionery softer and fresher for longer. In pharmaceuticals, it's used as a solvent for drug delivery and as a stabilizer in liquid medications. The cosmetic industry utilizes PG as a moisturizing agent in skincare and haircare products, improving texture and hydration.

Industrially, Propylene Glycol is a key ingredient in antifreeze and de-icing fluids due to its ability to lower the freezing point of water. It's also employed as a heat transfer fluid in HVAC systems and industrial processes, offering a safer alternative to ethylene glycol. Its utility extends to the production of unsaturated polyester resins and polyurethanes. Furthermore, it is a base ingredient in e-liquids for electronic cigarettes and is used to create fog effects in entertainment.

For businesses seeking to leverage these properties, sourcing high-quality, certified Propylene Glycol is essential. As a manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers USP and Food Grade PG, ensuring the purity and consistency required for demanding applications. We provide comprehensive technical data and support to assist clients in selecting the optimal grade for their specific needs, facilitating reliable procurement for all industrial and commercial requirements.
