Propylene glycol, also known as propane-1,2-diol, is a viscous, colorless liquid with a faintly sweet taste. Its chemical formula is CH3CH(OH)CH2OH, making it a diol due to its two alcohol groups. It is nearly odorless and miscible with a wide range of solvents, including water, acetone, and chloroform. Classified as generally recognized as safe (GRAS) by the US Food and Drug Administration, propylene glycol finds extensive applications across various industries.
Food and Drug:
Propylene glycol is widely used in food and drug applications, including coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products, and soda. It is a common ingredient in vaporizers, hand sanitizers, and pharmaceutical formulations as a solvent, humectant, and carrier. Many pharmaceutical drugs and capsule preparations utilize propylene glycol due to its solubility and carrier properties.
Antifreeze:
Propylene glycol is employed as an aircraft de-icing and anti-icing fluid due to its ability to depress the freezing point of water. It is used in both diluted and undiluted forms for de-icing aircraft fuselages and preventing ice accretion on wings and tail surfaces before takeoff. Additionally, propylene glycol serves as a substitute for ethylene glycol in automotive antifreeze formulations, offering low toxicity and environmental friendliness.
