PG and ink

[ranmanver]

My point in posting this is to let everyone know about another use for propylene glycol. I work in the printing industry. We use propylene glycol in our waterbased inks to slow the drying down if the ink is drying too fast. I looked at the bottle we have of PG and there is no USP certification on it. Also looked at the MSDS (material safety data sheet) and it said not to inhale the vapors. I have been vaping PG since i started vaping three months ago and i don't know of any side effects other than i seem to have a little more sex drive (which could also be related to no analogs). I tried some VG based juices and they made me sick to my stomach. I talked to the ink rep who sells us the PG and asked him if it was USP certified and he said he didn't know which prolly means i won't be "borrowing" any to cut my juice. It must have a few other additives in it. The rep is supposed to get me some more info on what is in the PG they sell us. If anyone else has already posted this info i apoligize.
