Propylene Glycol (CAS 57-55-6), also known as propane-1,2-diol, is a chemical compound of immense industrial and commercial importance. Its widespread use across pharmaceuticals, cosmetics, food, and various industrial sectors is testament to its unique and beneficial properties. As a leading manufacturer and supplier in China, we are deeply involved in its production and distribution, offering a reliable source for this indispensable chemical.

Chemically, Propylene Glycol is an organic compound with the formula C3H8O2. It's classified as a diol, meaning it possesses two hydroxyl (-OH) groups. This molecular structure imparts several key characteristics: it is a viscous, colorless liquid that is nearly odorless and has a faintly sweet taste. Its miscibility with water and a broad range of solvents like acetone and chloroform makes it an exceptionally versatile solvent and carrier.

Key Properties and Production:

• Physical Properties: Its low volatility, high boiling point (approx. 188°C), and low freezing point contribute to its utility in various applications, from humectants to antifreeze. The USP grade, in particular, ensures high purity essential for sensitive applications.
• Solubility: It readily dissolves many organic compounds and is completely miscible with water, making it a highly adaptable ingredient in diverse formulations.
• Production Methods: Industrially, Propylene Glycol is primarily synthesized from propylene oxide through hydrolysis. This process can be non-catalytic, conducted at high temperatures and pressures, or catalytic, using acids or ion-exchange resins. As a major manufacturer, we employ advanced production techniques to ensure consistent quality and yield.
• Low Toxicity: Propylene Glycol is generally recognized as safe (GRAS) for many applications, including food and pharmaceutical uses, making it a preferred alternative to other glycols with higher toxicity profiles.
