Key Features:
Hygroscopicity: Propylene glycol is hygroscopic, meaning it attracts and retains water molecules from its surroundings. This property makes it useful in applications where moisture control is important, such as in pharmaceuticals and food products.
Solvent Properties: It serves as a solvent for a wide range of substances, including flavorings, preservatives, and pharmaceuticals. Its ability to dissolve both polar and non-polar compounds makes it a versatile ingredient in various industries.
Humectant: Propylene glycol is commonly used as a humectant in personal care products, cosmetics, and food products to help retain moisture and prevent drying out.
Antifreeze Agent: Due to its low freezing point and ability to lower the freezing point of water, propylene glycol is used as an antifreeze agent in automotive coolants, aircraft de-icing fluids, and other applications where freezing temperatures need to be avoided.
Heat Transfer Fluid: It is utilized as a heat transfer fluid in various industrial processes, including HVAC systems, refrigeration, and thermal management applications.
Stabilizer and Thinner: Propylene glycol is used as a stabilizer and thinner in many formulations, such as inks, paints, and coatings, to improve viscosity and flow characteristics.

Applications:
Food and Beverage Industry: Propylene glycol is used as a food additive (E1520) and is Generally Recognized as Safe (GRAS) by regulatory authorities. It is commonly found in processed foods, beverages, and food coloring formulations.
Pharmaceuticals: It serves as a solvent and carrier for active pharmaceutical ingredients (APIs) in oral, topical, and injectable medications. It is also used in drug formulations, including creams, ointments, and lotions.
Cosmetics and Personal Care Products: Propylene glycol is a common ingredient in skincare products, moisturizers, shampoos, and cosmetics due to its humectant properties.
Industrial Applications: It is widely used in industrial processes for its solvent, antifreeze, and heat transfer properties.
Safety Considerations:
Propylene glycol is generally considered safe for use in regulated concentrations. However, high concentrations or prolonged exposure may cause skin irritation or allergic reactions in sensitive individuals. It is important to follow recommended handling and usage guidelines provided by regulatory agencies and manufacturers.
