 Excuse me, but I don't think anyone wants to ingest propylene glycol for any reason. Propylene is one of the alternatives to the super-toxic ethylene glycol, yet is not near at "pet friendly" as originally thought, and advertised.

Propylene glycol  used as a food additive? I've never heard of it, but I'd want it out of my Cheerios thats for sure.
