Monopropylene glycol is a highly viscous substance, yet fully miscible with water, alcohol, and most organic solvents. It has a boiling point of approximately 188°C and a freezing point as low as -59°C. This wide thermal range makes it a stable and versatile medium. In addition, propylene glycol is hygroscopic — it absorbs moisture from the surrounding environment — which is why it’s commonly used in the cosmetics and technical industries. It also has low volatility and high chemical stability, allowing for long-term storage and use in durable formulations. Importantly, propane-1,2-diol is not classified as hazardous to health when used properly, which further broadens its range of industrial and commercial applications.

Propylene glycol is a valuable energy supplement widely used in the feed industry, particularly in the nutrition of dairy cattle, where it helps prevent ketosis – a metabolic disorder that reduces productivity and overall animal condition. Its liquid form allows for easy and accurate dosing, whether added to feed or administered orally. In addition to supporting energy balance, propylene glycol – thanks to its physicochemical properties – helps improve the general condition of animals, positively influencing lactation, reproduction, and immunity.

Propylene glycol is widely used as a component of operating fluids and cooling liquids, as well as a carrier base in various technical formulations. It performs exceptionally well in systems that require stability and reliability, primarily due to its physicochemical properties — including a high boiling point, low freezing point, and resistance to oxidation.
