Propylene Glycol

Propylene Glycol is a chemical compound with various industrial applications. Here are some of its uses:

1. Humectant: Propylene Glycol is widely used as a humectant in personal care products, cosmetics, and pharmaceuticals to help retain moisture and prevent drying of the skin, hair, and other materials.
2. Solvent: It serves as a solvent in industrial processes, such as paint and coating formulations, cleaning products, and chemical synthesis. Propylene Glycol is a versatile solvent due to its ability to dissolve a wide range of organic and inorganic compounds.
3. Antifreeze: It is a key component in automotive antifreeze formulations, where it helps prevent the freezing of engine coolant in cold temperatures and also serves as a heat transfer fluid to prevent overheating in warmer conditions.
4. Food Additive: Propylene Glycol is approved for use as a food additive (E1520) by regulatory agencies worldwide. It is commonly used as a solvent, preservative, and humectant in food and beverage products.
5. Pharmaceuticals: It is utilized as a solvent and carrier in the formulation of pharmaceuticals, including oral, topical, and injectable medications. Propylene Glycol helps enhance the solubility and bioavailability of active pharmaceutical ingredients.
6. Cosmetics: Propylene Glycol is used in the formulation of cosmetics and personal care products, such as lotions, creams, shampoos, and deodorants, where it functions as a solvent, humectant, and viscosity modifier.
7. Hydraulic Fluids: It serves as a component in hydraulic fluids and brake fluids due to its excellent lubricating properties and low volatility.
8. Chemical Intermediates: Propylene Glycol serves as a precursor or intermediate in the production of various chemicals, including polyurethanes, polyester resins, and propylene glycol ethers.
