Your grasp of chemistry makes this so much easier to discuss pwmeek. Although USP PG is classified by the FDA as a sugar alcohol that is not to say that it is either a Fructose or Sucrose based sugar nor is it related to ethanol or alcohol used in beverages. PG does shares the same molecular base as sugars, monosaccharide being C
6-H
12-0
6, disaccharide C
12-H
12-O
6 and PG C
3-H

While structurally different than a monosaccharide or disaccharide its shared molecular formula I believe results in a very similar effect when subjected to heat. In this case it would be the heat from the atomizer. As I mentioned, is it truly carmelization? No. But I dont know what other word or analogy one could use or draw upon. Or if indeed there is such a word which could best describe this effect.
Experience shows us that after
vaping a carto for a couple of days the polyfill does indeed lose the ability to absorb e-liquid at the initial rate it once did. It can only be surmised that subjecting the e-juice to heat has a causal effect on the polyfill. This conclusion can be drawn since we know that juice can be stored in a cartomizer for months unused without affecting the absorbent qualities of the polyfill material.
Of the major flavor suppliers like Bickford, Capella, Flavourart, or Loranns, only Loranns states that its flavoring oils are sugar free. The other flavor suppliers do note that they utilize sugars in their flavorings primarily dextrose i.e. glucose. Given that there may or may not be sugar in your juices and the defined molecular base of PG
.what would or should one call the adverse effect of absorbency to the polyfill material after use? The best I can come up with is the analogy provided in my replies.
