recently I've come across something called ...biobased PG.....or plant derived PG.....I am not sure if this is some new marketing scam or not. my understanding was that PG was a byproduct of the biodesil process.....biodesiel seems like it is pretty much plant based...so I'm wondering if this is anything new....has anyone heard of this stuff and know anything about it,especially whether or not it causes the same sensitivity that our standard PG causes in some people.
