What is the freezing point of ethylene glycol CAS 107-21-1?
The freezing point of pure ethylene glycol is approximately -12.9 °C (8.8 °F).
However, its key function in antifreeze is to lower the freezing point of water. When mixed with water, the freezing point of the solution drops significantly.
Here is a common example:
A 50% ethylene glycol / 50% water mixture by volume will freeze at around -37 °C (-34 °F).
This property is why it is so effective at preventing engine coolant from freezing in cold climates.
