Propylene Glycol, commonly known by its CAS number 57-55-6, is a highly versatile chemical compound that serves as a cornerstone ingredient across a multitude of industries. Its unique combination of physical and chemical properties makes it an indispensable component in everything from industrial manufacturing to sophisticated pharmaceutical formulations and everyday consumer goods. As a leading supplier, we understand the critical role this chemical plays, and we are dedicated to providing high-purity Propylene Glycol that meets the exacting standards of our clients.

Understanding Propylene Glycol's Properties

At its core, Propylene Glycol is a viscous, colorless, and nearly odorless liquid. Chemically classified as a diol, it possesses two hydroxyl groups, which grant it excellent hygroscopic (water-attracting) and solvent capabilities. This allows it to be miscible with a wide range of solvents, including water, acetone, and chloroform. Unlike some other glycols, Propylene Glycol is recognized for its low toxicity and is even designated as GRAS (Generally Recognized As Safe) by the U.S. Food and Drug Administration for specific food applications, underscoring its safety profile for sensitive uses.

Key Industrial Applications and Benefits

One of the primary industrial uses of Propylene Glycol is as a chemical feedstock for the production of unsaturated polyester resins. These resins are vital components in the manufacturing of fiberglass-reinforced plastics and various surface coatings. Propylene Glycol's role here is crucial, contributing to the durability and performance of the final products. Furthermore, its excellent solvency and humectant properties make it a preferred ingredient in the pharmaceutical and cosmetic industries. As a pharmaceutical excipient, it acts as a solvent and stabilizer for active ingredients in oral, topical, and injectable medications. In cosmetics, it serves as a moisturizer, emollient, and carrier for fragrances and active compounds.
