It is CVS quality

Sold as pure glycerin, USP. Glycerin 99.5% anhydrous as a skin protectant. It is good stuff, others here use it and like it (that is where I got the recommendation).
As for the 2 year expirary, I call BS. That would be assuming I am opening it and slathering on my skin with dirty, nasty hands and the worst possible storage scenario. It is bacterostatic. Since I keep mine in a nice cool, dark closet and pour it into sterilized cylinders, I am going to use that bottle until it is empty or I notice a change in it. The bottles are clear, so if I notice a floater, odor or color change I think I can afford to dump it. It is easily replaceable. By buying it there on the 2 for 1 sales, I have more than I need any time soon anyway.
ETA: I am going to go out on a limb and assume it was made by either Humco or Proctor and Gamble and sold in bulk packaging by CVS. Humco bottles look exactly the same as the CVS though. I would think Humco gets it from P&G though.
