1,2-Propanediol, commonly known as Propylene glycol, is a synthetic organic compound with the chemical formula C₃H₈O₂. It is a colorless, odorless, and tasteless liquid that is hygroscopic and miscible with water, acetone, and chloroform. It is widely used in food, pharmaceutical, and industrial applications.
🏭⚗️ Production
Propylene glycol is industrially produced by the hydration of propylene oxide. This process can be done via non-catalytic high-temperature methods or catalytic low-temperature methods using an acid or base.
🔬 Properties
Propylene glycol is a viscous, colorless liquid with a slightly sweet taste. It is highly hygroscopic and has a low vapor pressure. It is chemically stable and compatible with a wide range of substances, which makes it suitable as a solvent and carrier.
🧪 Applications
• Food industry: Used as a humectant, solvent, and preservative (E1520) in processed foods and beverages.
• Pharmaceuticals: Serves as a solvent in oral, injectable, and topical formulations.
• Cosmetics and personal care: Commonly used in creams, lotions, deodorants, and hair care products for its moisturizing and stabilizing properties.
• Industrial uses: Used as antifreeze, coolant, and in the manufacture of plastics and resins.
