Propylene glycol is an organic compound, usually a slightly sweet, odorless, clear, colorless, oily liquid that absorbs moisture and is easily mixed with water, acetone, and chloroform. It is widely used in food, medicine and cosmetics industry. In the application of food grade propylene glycol, propylene glycol is an excellent raw material in flavors and spices, baking pastries, and has an irreplaceable position in the production of many products.
Propylene glycol in food is used for a variety of edible items such as coffee drinks, liquid sweeteners, ice cream, raw dairy products, and sodas. Vaporizers used to deliver pharmaceuticals or personal care products often include propylene glycol in the composition. Propylene glycol in food is used as a solvent in many pharmaceuticals, including oral, injectable, and topical formulations. Many insoluble drugs utilize propylene glycol as a solvent and carrier in water; benzodiazepine tablets are an example. Propylene glycol is also used as a solvent and carrier for many pharmaceutical capsule formulations. Additionally, some artificial tear formulations use propylene glycol as an ingredient.
Propylene glycol is used as an essence dissolving agent in tobacco oil.
