Antifreeze: Due to its low freezing point and high boiling point, Propylene glycol is widely used as an antifreeze, such as in automotive antifreeze. Question 3: What are the methods of preparing Propylene glycol? Propylene glycol can be prepared by the following methods: By propylene oxidation:...
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...

propylene glycol, is used in the food processing field as a preservative. It is not harmful to humans and is not harmful to plants. Propylene glycol-based antifreeze has no known affect on grass and should be used in place of the ethylene glycol as antifreeze ...

For the environmentally conscious, you can also get antifreeze that is propylene glycol based. The main difference is that it is less toxic than ordinary ethylene glycol antifreeze (reduces risk of accidental poisoning if the cooling system leaks and an animal licks it up)....
I have also found foods that contain antifreeze =propolene glycol. It is used as a cheap sweetner and an anti-freezing agent. Please check what you are consuming ,some ingredients are hardcore drugs #1 is caffeine it is a replacement for cocaine. Log in to Reply Em October 12, 2016 ...
NOTE:While propylene glycol-based antifreeze is indeed pet-safer, it is by no means pet safe. Caution is still needed, but the risk associated with propylene glycol is less. Here are some PG antifreeze brands that are safer for use around pets, stray cats, and wildlife: ...
mixture a mixture of water and antifreeze such as propylene glycol (which is used in the food industry) is used as a heat exchange fluid to protect against freeze damage down to a locally determined risk temperature that depends on the proportion of propylene glycol in the mixture [translate]...
Breaking the Old Antifreeze Habit There are advantages to using only one type of coolant, both for newer and for classic cars. Classic car owners traditionally use inorganic acid coolants, the ones that are ethylene-glycol-based and bright green in color. If you own a1976 Cadillac Coupe Devil...
