Question about VG

[Topdogie01]

I have a bottle of Glycerol, Reagent A.C.S. (500ml) and was wondering if it would be safe to use for vaping or not? and how does its purity compare to that of USP grade? ive seen some lists that say its ACS then regent, then USP grade.

If its Reagent ACS-1 looks fine:

Glycerol Glycerin Reagent Acs 1l by Scientific Strategies at the ICNC Industrial and Scientific Supplies




MUST BE usp grade for human consumption.

see, thats what i was thinking. but wouldnt a higher quality be better? trying to decide if i want to use it to vape or let wife use it for her homemade soaps and lotions.

but thinking that if acs grade is higher than usp, wouldnt it still be fine to use and possibly better than usp as its a higher grade?

(tired, lack of sleep due to insomnia and acid reflux)

 

[Topdogie01]

bump, any others to chime in?

Looked good to me. I just looked at the analysis summary and it seemed pretty good. There was not bubble headed robot waving pincers around intoning Warning Warning in my head when I looked at it.

 

[Topdogie01]

ok. wasnt sure how the acs compared to usp grades for vaping. since it seems acs is a higher purity from what i have read.

Mix up 5ml batch and give to somebody you don't like. As long as they don't fall out and start foaming at the mouth it's probably ok.

Seriously, wonder if it tastes different. You sampled it? Finger-Tongue test?

 

[Hoosier]

Not entirely sure myself. USP covers quite a bit, more than just purity, but it is the purity that we're usually worried about.

 

[psycheval]

1. A.C.S.

A chemical grade of highest purity and meets or exceeds purity standards set by American Chemical Society (ACS).

2. Reagent

High purity generally equal to A.C.S. grade and suitable for use in many laboratory and analytical applications.

3. U.S.P.

A chemical grade of sufficient purity to meet or exceed requirements of the U.S. Pharmacopeia (USP); acceptable for food, drug, or medicinal use; may be used for most laboratory purposes.


Reagent A.C.S. - This designates a high quality chemical for laboratory use. The abbreviation "A.C.S.," means the chemical meets the specifications of the American Chemical Society. A Certificate of Analysis is available upon request.

Reagent - The highest quality commercially available for this chemical. The American Chemical Society has not officially set any specifications for this material.

ive tasted a small drop of it and cant tell any difference to walco glycerin. was just wanting to check with more experienced users to see if they knew anything. guess i may be the first one to use it on the forms who is posting about it. didnt see any other threads on its use.

Way I read all that mumbo jumbo is this stuff is better quality than USP. It is as high quality as can be made(ACS). USP just meets the standards ACS exceeds them. You got my attention.

 

[Red_Bird]

From my understanding if it is USP and KOSHER vg it is the best you can use in the making of eliquid and consumption.

If it IS NOT KOSHER give it to the wife for soap.

I'd not use it if it were not kosher (and I'm not Jewish, lol).

HeHe. Confused now for sure! Just testing differences from what I'm finding. Don't know what those are. No doubt we know USP is ok but somebody that knows what they are looking for in each test is needed to explain the difference in the standards. May already be known at the ACS standard it's not necessary to test the same as USP because it's already included? Don't know.
Call the buddha.

Nope, they are different standards. USP allows more chlorinated compounds than ACS while ACS allows more sulfate compounds than USP. They differ slightly with lead too, very slightly. Both have good purity and the ACS is better overall, but there are differences with specifics. (The differences are fairly small though.)

I know USP also has standards for packaging, environment of the packaging area, handling, and expiration. I don't know enough about ACS to know if it covers factors other than purity. I don't see anything wrong with ACS, but I'm not sure the difference is worth the extra $. Now if the flavor is more neutral for the ACS, then I would be more likely to try the ACS myself.

My thoughts also.
