Storage & shelf life of DIY componets
I'm wondering what the best way is to store PG, VG, Nicotine, and flavors. Also what is their shelf life. I'd hate to buy more chemicals than I can use before they go bad. I could make enough room to freeze them if that would extend their life, but is that necessary?

RE: Storage & shelf life of DIY componets
Good question. I bought a gallon each of VG and PG in October, and have a ton left. It is at room temperature in a dry, dark place. Hoping that's OK.

RE: Storage & shelf life of DIY componets
The diluents have a shelf-life of a year or two. Keeping them in a freezer will increase this but VG at -25C is a royal pain in the butt to work with. I keep my working stock of diluents on the kitchen work top. Nicotine I freeze and keep 30-60ml at room temperature as working stock.

Flavours I keep in a cool dark toolbox in the cupboard under the stairs.

I tend to get through ingredients at a faster rate than most - I've shipped out a couple of litres of juice in the last month. Shelf-life isn't really an issue for me Smile

So what's the max for pg and vg if kept in the freezer ? out of interest, saying that i can't see me keeping enough to last any longer than two years lol

RE: Storage & shelf life of DIY componets
What's exactly meant by shelf life? Does it taste funny? Is it unsafe? What makes it expired?

RE: Storage & shelf life of DIY componets
Well I just ordered everything, PG,VG, 100mg Nicotine, four flavors, and ten 10ml blunt tip syringes. I already have about 15 bottles so didn't order more of them. I bought small quantities to see how fast I use them. Got 1 liter each of VG and PG, 250ml of 100mg nicotine, and 1oz each of four different flavors. At least it's a start and I'll see how it goes.

My guess (and only a guess) is that biological growth as in mold or bacteria would be the main problem. The bugs can spoil just about anything that does not kill them.

Let us know how make out.  The way I'm going thru juice, I can see myself as a home chemist.

RE: Storage & shelf life of DIY componets
PG is widely used as an antibacterial. If it is clean, I'd reckon it'd last a decade or more.

Any "expiry" date on it is probably CYA rather than anything else.

Some things on general sale have a wildly optimistic "Best Before" date. Coffee and flour come to mind.

Coffee really does not store at all well.

Neither does store-bought flour.
