Polypropylene Glycol

Polypropylene Glycol (PPG) is a multifunctional glycol compound widely used in industrial, consumer, and specialty applications. Known for its solvency, humectant properties, low volatility, and lubricity, PPG is available in a variety of molecular weights, making it adaptable to a broad range of formulations. In industrial processes, polypropylene glycol plays an important role in polymer chemistry, lubricants, heat transfer fluids, coatings, and adhesives, where it enhances stability, flow, and durability.

Beyond industrial uses, polypropylene glycol is applied in cosmetics, personal care, and pharmaceuticals, where it functions as a carrier, emollient, and moisturizer in lotions, creams, shampoos, and other formulations. In pharmaceuticals, PPG is valued for its role in drug delivery systems and as a safe excipient. It is also used in antifreeze formulations, de-icing solutions, and hydraulic fluids, where its thermal stability and low toxicity make it a reliable choice. With its balance of performance, versatility, and safety, polypropylene glycol continues to be a critical material across industries such as automotive, construction, healthcare, coatings, and specialty chemical manufacturing.
