Propylene glycol used to be in vehicle antifreeze.
Propylene glycol has covalent bonds.
The chemical formula of propylene glycol is C3H8O2.
Propylene glycol was proposed as an air germicide; it is also an ingredient in antibacterial solutions.
Propylene glycol in fireball
Any substance that lowers the freezing point of water such as ethylene glycol or propylene glycol which are commonly added to water
Most of them contain propylene glycol.
Propylene glycol.
Ethylene glycol
Yes, Ethylene glycol and Propylene glycol are very similar chemically, therefore, can be mixed without any bad consequences for the engine.
I don't know tbh.
You could determine its boiling point. The boiling point of ethylene glycol is 197.3 oC, and the boiling point of propylene glycol is 188.2 oC.
