Mono Propylene Glycol USP (also known as propylene glycol, PG, propan1, 2diol and MPG) is a clear, colourless, and viscous liquid with a characteristic odour. It has the formula C3H8O, is soluble in water, and has hygroscopic properties. MPG is used across a wide range of industries as it has low toxicity, coupled with a freezing point which is depressed upon mixing with water.
