Propylene glycol is a colorless, nearly odorless, clear, viscous liquid with a faintly sweet taste. It is hygroscopic and miscible with water, acetone, ethanol, diethyl ether and chloroform. It is the main ingredient in products such as fog oil for theatrical fog machines and insecticidal smoke fog oil. It can also be used in pyrotechnic smoke mixtures (especially color smoke mixtures) to prevent dyes from "dusting" into the air and provide more smoke density in combustion, and as a dampening agent to control airborn dusts while mixing. Other uses include; mixing with wax and gelatin in the manufacture of paintballs, as a wetting agent to control drying times of paints and lacquers, as a non-toxic antifreeze for winterizing drinking water systems in campers and motor homes, septic systems, etc., to de-ice aircraft and airstrips, as a moisturizer in foodstuffs, medicines, cosmetics, etc.....
