Propylene glycol is used:
  • As an ingredient in the oil dispersant Corexit, used in great quantities during the Deepwater Horizon oil spill. As a solvent in many pharmaceuticals, including oral, injectable and topical formulations (notably, diazepam, which is insoluble in water, uses propylene glycol as its solvent in its clinical, injectable form)
  • As a humectant food additive, labeled as E number E1520
  • As an emulsification agent in Angostura and orange bitters
  • As a moisturizer in medicines, cosmetics, food, toothpaste, shampoo, mouth wash, hair care and tobacco products
  • As a carrier in fragrance oil
  • To produce polyester compounds
  • As a base in deicing solution
  • As an ingredient in massage oils
  • In hand sanitizers, antibacterial lotions, and saline solutions
  • In smoke machines to make artificial smoke for use in firefighters' training and theatrical productions
  • In electronic cigarettes, as a vaporizable base for diluting the nicotine liquid
  • As a solvent for food colors and flavorings
  • As an ingredient, along with wax and gelatin, in the production of paintballs
  • As a moisture stabilizer (humectant) for snus (Swedish style snuff)
  • As a cooling agent for beer and wine glycol jacketed fermentation tanks
  • As a nontoxic antifreeze for winterizing drinking water systems (for example recreational vehicles), and in applications where the used antifreeze eventually will be drained into the soil, water, or a septic system
  • As a less-toxic antifreeze in solar water heating systems
  • As a solvent used in mixing photographic chemicals, such as film developers
  • In cryonics
  • As a working fluid in hydraulic presses
  • As a coolant in liquid cooling systems
  • To regulate humidity in a cigar humidor
  • As the killing and preserving agent in pitfall traps, usually used to capture ground beetles
  • As an additive to pipe tobacco to prevent dehydration
  • To treat livestock ketosis
  • As the main ingredient in deodorant sticks
  • To deice aircraft
  • As an ingredient in UV or blacklight tattoo ink
  • As a lubricant in air conditioning compressors
  • As a wetting agent, used to determine drying time in paints and coatings
  • Used in the beverage mixer Sweet N Sour.
Propylene glycol has properties similar to those of highly toxic ethylene glycol (monoethylene glycol or MEG). (Note: infrequently, propylene glycol may also use the acronym MEG, but as an abbreviation of methyl ethyl glycol - the industry standard acronym for propylene glycol is PG or MPG (monopropylene glycol).) The industrial norm is to replace ethylene glycol with propylene glycol when safer properties are desired.
