Propylene glycol is clear, colorless, and almost completely odorless. It is a slightly viscous, water-soluble, and hygroscopic liquid. PG is essentially a synthetic liquid substance that carries the profound ability to absorb water. It even has the ability to absorb water from the air around it, making it valuable to products which need to maintain moisture. The Food and Drug Administration (FDA) has classified propylene glycol as an additive that is safe for use in food.
