What is the difference between propylene glycol and ethylene glycol?

What is the difference between propylene glycol and ethylene glycol?

The number one difference between the two glycols is that ethylene glycol is toxic and propylene glycol is not, allowing propylene glycol to be purchased as food grade in addition to the technical or industrial grade. 50% propylene glycol has a freezing pointof -31°F, where 50% ethylene glycol freezes at -36°F.

What is poly propylene glycol used for?

Polypropylene glycols are liquids, mostly insoluble in water, used to suppress foaming in industrial processes and for making polyurethane resins, hydraulic fluids, and various other materials.

What is ethylene glycol used for?

DESCRIPTION: Ethylene glycol is a useful industrial compound found in many consumer products. Examples include antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films, and cosmetics. It can also be a pharmaceutical vehicle.

What is the difference between polyethylene glycol and ethylene glycol?

The key difference between ethylene glycol and polyethylene glycol is their chemical structure. Ethylene glycol is a simple linear molecule, whereas polyethylene glycol is a polymeric material. In addition, both of these compounds are commercially very important and used in a number of applications.

Which is better ethylene or propylene?

The difference between Propylene Glycol and Ethylene Glycol in antifreeze comes down to both toxicity levels and efficiency of performance. Ethylene glycol possess far superior heat transfer properties whereas Propylene Glycol carries a very low toxicity.

Can you replace propylene glycol with ethylene glycol?

Can I mix propylene glycol with ethylene glycol? Yes, they can be mixed. They would not cause any harm to the cooling system, but it does slightly weaken the heat transfer.

What is the difference between polypropylene glycol and propylene glycol?

Abstract: Propylene Glycol is an aliphatic alcohol manufactured as a reaction product of propylene oxide and water. Polypropylene Glycol is a polymer formed by adding propylene oxide to dipropylene glycol.

Is propylene glycol toxic to humans?

Summary Propylene glycol has very low toxicity. Poisoning rarely occurs, and it is typically due to high doses of medications that contain it.

Is propylene glycol the same as polypropylene glycol?

Can I mix propylene glycol and ethylene glycol?

What are the dangers of propylene glycol?

Uses Of Propylene Glycol. Its use for pharmaceutical purpose is well known,it is included in oral,injectable and topical preparations.

  • Propylene Glycol Dangers. Damage to kidney and liver.
  • Side Effects Of Propylene Glycol.
  • What are the uses of ethylene glycol?

    The manufacture of fiberglass used to make products such as jet skis,bathtubs and bowling balls.

  • The manufacture of ink for ballpoint pens and other inks.
  • Heat transfer fluids such as industrial coolants for gas compressors,heating,ventilating,and air-conditioning systems and ice skating rinks.
  • What are the side effects of inhaling propylene glycol?

    If gaseous form of propylene glycol in inhaled,there may be breathing difficulty; in certain cases oxygen supplementation may be necessary.

  • Propylene glycol can cause irritation in eyes,causing burning of eyes.
  • Propylene glycol is extremely flammable therefore it should be stored with all precautions.
  • Is propylene glycol the same as antifreeze?

    Propylene glycol. Propylene glycol is considerably less toxic than ethylene glycol and may be labeled as “non-toxic antifreeze”. It is used as antifreeze where ethylene glycol would be inappropriate, such as in food-processing systems or in water pipes in homes where incidental ingestion may be possible.
