i looked into it once, and i dont think you can extract the THC into that. But it does mix with alcohol readily, and alcohol has a lower boiling point, so if you extract into alcohol, then mix with propylene glycol, and then evaporate the alcohol off, then you should be left with a pretty clean product, whatever that may mean as far as propylene glycol is concerned.
