PG, VG, and dehydration

[mrtiedye]

From what I have gathered, one of the more common uses of both PG and VG is as a moisturizer in cosmetics. Their chemical make-up somehow allows them to trap moisture from the air and retain it in your skin, making you all silky and smooth.

So why does vaping these liquids make our throats dry out? Shouldn't it have the opposite effect? Am I am overlooking something obvious? Any chemists out there that can break this down to Sesame Street level for me?

EDIT: To make things even more confusing, letting PG come in contact with your skin makes your skin dry and irritated? But it is used in cosmetics for the exact opposite reason, because it makes your skin more moist?

I am far from an expert as I am VERY new to vaping, but I seem to find that I get the "dry throat" feeling more with flavors I am vaping than from the PG or VG. I tend to like herb and spice flavors such as peppermint, cinnamon and clove. I find that those flavors will cause me to feel like I am experiencing a dry throat more so than a dessert flavor, coffee or fruit flavor. Also, the higher the nicotine level, the more I feel dryness in my throat. So, I agree with you, maybe one of the folks on here that mix their own juices know more about this and can explain it.

I'm not a doctor and I don't play one on TV.

But as I understand it the same thing happens in your blood stream. Water is bound up with the PG/VG and is not allowed to flow freely in cells.

As my user name states, I'm no expert. I read both PG & VG are humectants. Here's some info on them: What is an Humectant?

Both will absorb moisture from your body, leaving you dry, dry, dry, which I suspect is because you exhale the vapor with that moisture. Being some other form in make-up and lotion, they stay on your skin and absorb ambient moisture. Just my logical guess.

I think it is used in food and cosmetics to retain moisture...so it draws moisture in. When inhaled...it removes moisture by drawing moisture in as it does in food products...just my best guess.

Thanks for your replies. Although I still haven't found anything solid on the subject, what JustAGuy said makes sense. Since the PG and VG attract water, as we exhale it, it takes the water from our throat and lungs with it.

What zoiDman said kind of makes sense with the skin irritation resulting from spillage. By itself, it just soaks up all the moisture and keeps it all to its greedy little self. But when mixed with other chemicals, it helps them collect moisture and replenish your skin.

Hmmm, as JustAGuy said, this is all just logical guesses. I do feel a little closer to understanding what is going on here. I just hope we are going in the right direction. Thanks so much for all of your input.

mrtiedye (I made some of that in school ), it may interest you to know that cigarettes also contain humectants, along with another 598 additives. When you burn it, it releases possibly another 4,000 chemicals...from Wiki. This is got to be better.

p.s. check the Health forum on ECF for more.

Getting nicotine on your skin is irritating - it is a known skin irritant. And vaping medium or high nicotine in 100% PG can be irritating. PG lets through the most flavor, and the most of nicotine's TH and irritation. VG dulls/smooths everything PG lets through and adds thicker visible vapor. But VG is thick and doesn't work well in many methods of vaping. Reservoir cartos and tanks like 20-30% VG, a it thicker may be OK especially if you or the vendor thins it. And I find stuffing cartomizers work well longer with thin juices so I use 20% or less VG in these.

BTW vaporized PG is used for inhalation therapy in hospitals, even for lung transplant patients. It is also concert fog.

Could It have anything to do with nicotine content?

I'm not sure how to link to another thread on my phone, but if anyone is interested in something (besides drinking water of course) to help with the dry throat, look for a thread called "dehydration advice" in the medical subforum
