Exact same Product supplied by many Vape suppliers only in different packaging.
USP GRADE! I have Bottles from Wizard and a smaller one from Walmart - Both Smell, Vape, taste identical.
Your .5 other is for FDA approval but can be as simple as moisture absorbed. If stated as 100% any discrepancy would shut down production.
Apparently not the same in all cases, or it wouldn't smell like baby powder.
I wasn't being argumentative. However, you can get it by the gallon too...from vaping stores...
If you want it to smell like babypowder (like the OP said it did, not me)...go ahead.
When they manufacture it for hand cream, there's no guarantee even if it says USP. Just FYI on USP alone on the label....it means the manufacturer claims to adhere to USP standards...that it's made according to quality standards, but it doesn't indicate purity as in 100% VG. For example, I'm sure it's high quality hand cream/lotion. The USP doesn't test/confirm it though unless it says USP Verified.
If it smelled like bably powder...I wouldn't vape it. But you wish to argue, fine. You can vape it.
Just for fun, here's another link copied from another thread on this:

PG and VG by the gallon, for example.
EDIT: And from above too. lol. good 1 Jfaria1891.
If you like what you use, fine. But I just don't think that USP means that it's intended for consumption (food grade) unless it's a food product.
