Sometimes, people confuse propylene glycol with ethylene glycol. Their chemical structures are similar, and both are used in antifreeze, but they’re not the same. In antifreeze, propylene glycol lowers the freezing point of water, which keeps the antifreeze product liquid. It replaces ethylene gl...

What is propylene glycol, and is it safe?Define “safe”. Can you drink it - no. Can you pour it in your eyes - no. Can you be in a car that uses it as antifreeze - yes. Until you define what you mean by “safe”, nobody can answer your ques.. How do I convert ethene to...
Propylene glycol is used by the chemical, food, and pharmaceutical industries as an antifreeze. It is a solvent for food colors and flavors, and in the paint and plastics industries. Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in ...
Propylene glycol 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. It is used as a humectant in foods and cosmetics. It is used as...

The Life Cycle Assessment (LCA) performed on ethylene glycol based antifreeze solution and propylene glycol based antifreeze solution shows that the energy required by the ethylene glycol based solution is less than the energy used by the propylene glycol based solution. The propylene glycol based ...
