Propylene glycol is sometimes confused with ethylene glycol, as both have been used in antifreeze due to their low freezing points. However, these are not the same substance.

In antifreeze, propylene glycol lowers the freezing point of water, which keeps the antifreeze product liquid. It replaces ethylene glycol in antifreeze, an ingredient that did the same thing but ...

The specific heat capacity of ethylene glycol–based water solutions is less than that of pure water. Propylene glycol, another common coolant, has an even lower specific heat. Of all common ...

Propylene glycol appears in many processed foods, and the U.S. Food and Drug Administration considers any product with below 50 grams of propylene glycol per kilogram to be safe.

Antifreeze stops the water in the primary loop of a cooling system from freezing should the outdoor temperature become too ...

Antifreeze is made of ethylene glycol or propylene glycol and is the basic ingredient, but it has to be mixed with water to create coolant, which is the cocktail you will find in the cooling ...

NEWARK, Del, Feb. 12, 2025 (GLOBE NEWSWIRE) -- Global sales of biobased propylene glycol are rising steadily, with a compound annual growth rate of 4.8% projected from 2024 to 2035. The market ...

About Propylene Glycol. Propylene glycol (PG) is a clear, odorless, and viscous liquid that is miscible with water and many organic solvents.It is a small molecule that is structurally different and ...

A pig kidney that had been removed from its host and frozen 10 days earlier, was thawed and prepared for a transplant experiment at Massachusetts General Hospital in March.

There are two checks you can easily do on your coolant: whether you have enough of it and if it’s still protecting your engine in cold temperatures.
