Propylene Glycol is an organic compound. Large amount of it is used in the plastics industry for the manufacture of polyester fibers and alkyd resins. It is used as a main ingredient in automobile antifreeze and engine-cooling liquids and in brake and hydraulic fluids due to its useful properties of low freezing point, involatility and low corrosive activity. It is used in the preparation of body-care surfactants and also as a humectant in foods and cosmetics. It is used as a solvent for colouring or flavouring agents as well as in many oral, injectable or topical pharmaceuticals. Its antibacterial property is applied in the preparation of sanitizing lotions.
