This ^^^...
Propylene glycol replaced Ethylene glycol in many antifreezes.
Propylene glycol is in many of the foods we eat - from ice cream to salad dressings. We likely ingest more of it than we realize. Ask a vaper about propylene glycol, it's the primary ingredient in many electronic cigarette juices.
It's also in many dog foods, but most people don't read the ingredients.
