Propylene Glycol

[Claasy]

I found USP grade pg on ebay at $1 an ounce, with $3 flat shipping nomatter how much you buy. Would this be a good match for me? I'll mostly just be vaping a bit on the weekends, not every day, so no need to be buying gallons of the stuff. How much do you think I should buy though, and is this even worth it? I have no idea how much I'd be going through.

Also, there's one thing thing that confuses me in the title. It says
100% Pure PROPYLENE GLYCOL Cigar Humidor Solution 50/50

What does the 50/50 mean?

I'd post the link, but I don't have enough posts yet to do so. I found it by searching for 'propylene glycol' on ebay, then selecting 'buy it now only', and 'lowest price shipping included'. It was the first on the list.


Either way, here's a snippet from the listing:

100% Propylene Glycol


This is the same Glycol we use in our top quality gel humidifiers. This is Propylene Glycol to be used for make solutions for your fine cigars. This is NOT Dipropylene Glycol used in making scents etc.


We are selling it in a 100% solution so you can dilute it to make whatever solution you need. We will always send it in a bottle larger than the amount you order so you can make you solution by simply adding water to the bottle we send

I would stay away from any mixtures listed as 50/50, that is more than likely 50% PG and 50% (something else). If you are unsure about the source, request an MSDS sheet.

Most Propylene Glycol USP is ~99.5%.

the 50/50 is PG Propylene Glycol and the other 50% is distilled water. In my opinion this is not a good combo for DIY mixing for electronic cigs. My mixes rarely use distilled water if any.

But in the description it says "100% solution so you can dilute it to make whatever solution you need"
