Propylene glycol is a synthetic organic alcohol with the ability to attract and retain water. Propylene glycol has a variety of functions in a myriad of industries, including pharmaceutical, food and beverage, and personal care. Below are only a few uses of propylene glycol in these industries.
When propylene glycol’s purity exceeds 99.8%, USP and EP deem it acceptable for foods and pharmaceuticals. In this form, propylene glycol can be used as a solvent for aromatics, in elixirs for pharmaceutical compounds, as a humectant for the salivary glands to wet the mouth, or as a solvent and emulsifier in sunscreens and lotions.
The pharmaceutical industry adds multi-purpose propylene glycol as an inactive ingredient in oral, injectable, and topical medications. Because it decreases the viscosity of liquids, propylene glycol makes oral medications easier to pour. As a stabilizer, propylene glycol helps to deliver the precise amount of medication with each dose.
Dairy and brewing industries find propylene glycol’s properties convenient in low temperature heat-transfer fluids. Grocery stores often rely on propylene glycol in food display cases for this same reason.
The food industry has three separate but intertwined uses for propylene glycol: as a preservative, a stabilizer, and a humectant. Coffee, tree nuts, soda, baked goods, and salad dressings are only a few products that list propylene glycol as an ingredient as it helps deliver the same amount of flavor and moisture with each bite or sip.
Many cosmetics, including moisturizers, soaps, deodorants, facial cleansers, shampoos, and conditioners, contain propylene glycol as a moisturizer, solvent, and humectant. As a dispersant, propylene glycol is added to fragrances so the exact amount of odor is released with every spray.
