Would you brush your teeth with anti-freeze from your car's radiator?

Absolutely NO, WHY include this ingredient in toothpaste if it is considered harmful??

You are confusing PROPYLENE Glycol with ETHYLENE Glycol. Propylene glycol is not toxic. Ethylene glycol is the substance in engine coolant which will damage internal organs, especially the kidneys.

Check out the MSDS for both substances for further information.
