Hi there
i have managed to get my hands on some AR grade Glycerin and Propylene Glycol from a chemical and lab equipment Supplier...
does anyone know if this is suitable for vaping ?
the Bottles labeling states the following :
Glycerin AR (2.5 liter)
Assay - Min 99.5%
Chloride - 0.0005%
Heavy Metals - 0.0002%
Sulphite - 0.001%
Propylene Glycol AR (2.5 liter)
Boiling Range/95% between 185' & 189'
chloride - 0.02%
Sulphate - 0.06%
Acidity - 0.3ml N%
i saw online that VG (USP) can have up to 5ppm of Heavy Metals, while the AR only shows 2ppm of Heavy Metals, so seems better ?
I found this Chemical Grade level chart online...
AR stands for Analytical Reagent, which would be the Reagent option in this chart
Chemical Grades
Below is a list of chemical grades in order of purity, from highest to lowest.
ACS
Highest quality; often equals or exceeds the latest purity standards set by the American Chemical Society (ACS). This is the only universally accepted standard. Chemicals are of the highest purity attainable.
Reagent
Purity is generally equal to ACS grade. This grade is suitable for analytical work and is more than adequate for general lab use.
USP
A grade of sufficient purity to pass certain tests prescribed by the US Pharmacopoeia (USP); acceptable for drug use. USP grade may be used for most laboratory purposes.
NF
A grade of sufficient purity to meet the standards of the National Formulary (NF).
Lab
An upper-level intermediate quality. Exact impurities may not be known; however, lab grade is usually pure enough for most educational laboratories.
Pure
Purified, pure, or practical grade; a lower-level intermediate quality.
Although this grade does contain impurities, it is usually pure enough for use in educational laboratories.
Technical
A good-quality grade used industrially. Use caution when substituting for reagent-grade or lab-grade chemicals.
in conclusion... are these chemicals suitable for vaping ?
any info would be much appreciated
Attached are pictures i took from the labels
