I was referring to the word, topical, which includes any of the exposed mucous membranes, but we'd be getting into semantics on that one :D

And as an aside, yes, your eye is considered topical use. Uses have to be specific, and warnings specific, if a topical product cannot be used on (given the example) your eyes.

Existing tests (primarily for PG in this link) can be found here: Propylene Glycol Research Study Results and here (generic pv safety): Studies suggesting PV safety

USP does not apply to use in any way. However, USP grade materials are whats used for any tests. It applies to purity, consistency, quality, etc. FDA tests for use, USP tests for quality.

USP Grading has been tested as safe to use for medical purposes in inhaled forms (think asthma inhalers). Not the quantity, etc, we are using it at, but PG and VG are not bio-cumulative, and only can cause temporary respiratory irritation. The word "safe" as used is "safe" to our knowledge...

Well then, I guess its a good thing thats not what he was doing. Which would be obvious if you read it.

.... Please look at whats in quotes. As in, what is inside quotes, EXACTLY. Unchanged. Not separate. As in, put together EXACTLY as what was written. I said, a bottle is not allowed to say quote USP Vegetable Glycerin, unquote. It can be VG, and say that it is VG, but if it says USP...

There are three bottles. Purple with a yellow label. Clear with a purple label. Clear with a white label. You're being a jackass. I mean hell, everyone goes to work carrying their bottle of glycerin, right? :rolleyes: I'm done with this thread.

Look past the first two google links.

Like I said, there are three types of bottles. Google it if you'd like. EDIT: I'm at work. I don't carry it with me. Look for the clear bottle with the white label.

You'll notice that it does not say "USP GLYCERIN" anywhere on the front of that label. You'll also notice that the one you posted is one of three styles of NOW brand glycerin bottles, if you care to look. Now. Again. It CAN NOT SAY "USP VEGETABLE GLYCERIN" Only "USP GLYCERIN" As the...

LOL I don't know if I have any more in me for this subject, tbh :)

Wow. I'm done. I'm going to start banging my head into the table soon. Below "NOW" ---- HERE ---- Above "Vegetable" Unless they've changed their label very recently (like in the past week or so), where I put "HERE" it says "USP GLYCERIN" omg no really? wow! *sigh*

Nightshadow, thats a web site, not the label on the product. Buy it, read the label. It will say "USP Glycerin". This has even been touched on by pharmacists. What you're reading is the marketing materials, essentially. They can say what they want, the label MUST say "USP Glycerin" not...

Its been a long while since ive had an issue... pretty much nothing since quitting smoking.

Or skincare products, various foods.... etc. :)

Eleven... And my favorite line? We know not everyone can easily quit, even with a good PV. For a smoker using (what we know to be) a lesser quality model to cut down, that says something. And from studies from these same anti-smoking groups that hate the e-cig, every single cigarette you...

Yup - but kosher and vegan being philosophical issues (or allergy issues, in case of peanut/pork/etc).... glycerin is glycerin. Claiming USP Glycerin is "toxic" and "dangerous" and "glycerin should not be used, only VG!" is just plain silliness.

You're right, that should be added onto the last sentence. But to meet USP requirements, that should not be a factor.

Which is why those with nut allergies should not be using glycerin - its been covered in the new members section, the health section, etc.
