Nicotine degradation over time

[RollandOfGilead]

Stumbled across this and though I would share it. Will be very interesting to see the results in a year or two.

Sounds like I should invest in a mini fridge.

Cool..... I'm trying to lower my nic over time anyway.....
seems that in the words of Mick Jagger and the Rolling Stones: "Tiiiiiiiiime IS on my side, yes it is!"

From early results, it's pretty minimal for "regular" storage, capped bottle at room temp hasn't dropped too much. I don't imagine too many people are leaving their juice in the window, let alone without a cap on. I'm curious what type of bottles they're using, amber/cobalt glass or plastic? Good to know my DIY supplies aren't going to be dropping any time soon regardless.

That or just buy 48mg and plan on it being 36mg in the year 2016.

This is the way to go lol, 50$ on Kijiji, it even has a beer rack lmfao..

Hoog isn't really monitoring Nic degradation with the open bottle. He's monitoring moisture absorption from the atmosphere diluting the sample.

I would think the "moisture" would evaporate faster or just as fast as it is "absorbed".

I'm mostly interested in the results for the closed bottles in the "fridge" or "office". This will determine if keeping them in a drawer is detrimental enough for me to invest in a mini fridge.

The open bottles are examples for people who steep this way(i think) not something that i can imagine any one does for months on end.

Pure PG and VG absorb water vapor from the air.
Takes time, but they will eventually dilute.

Plastic is more pourous than glass also. I'd have REALLY liked to see the same conditions but with a glass line up also (I assume they're just using the standard frosted plastics, but don't know for sure)

I would have liked to se some brave soul do a taste test as well.

Nic degrading or not, I feel like the brew inside the open-sunny-window bottle is just NASTY by month 2. Blergh.

Probably not as bad as nic juice stored in the bottom of someone's closet in plastic bottles (with their running shoes)
Neither PG or Nicotine are inert molecules. Long term exposure to the oxygen in air will initiate some chemical reaction.
Water vapor in the air will be absorbed due to the hygroscopic properties of PG. If left open, the water absorbed will reach an equilibrium point depending on the temperature and relative humidity of the air.
At a 70 degree F room temperature, and 50% RH the equilibrium point is about 80% w/w PG.
Water absorption goes up with a higher RH.

Thanks for the link, my nicotine bottle is now in the fridge!
