Not sure if it is still the case, but several years ago there was some chemical used in some flavour concentrates which caused cracking/crazing/clouding in some plastic clearos/tanks.
I recall cinnamon being super bad for it... also common in some citrusy flavours.
Do these flavours still cause this problem with some plastics? Or have they changed the formulas? Any info on whether or not the flavours that do this are worse for our health than other flavours that don't crack tanks?
I have a few old flavour concentrates, doublers and triplers left over from 5-6 years ago.
Recently returned to vaping after reverting back to cigarettes for a few years - most of my old juices both diy/bought have gone really dark colours so they will be thrown out... basically anything with nic has gone dark. But I have no-nic doublers/triplers and a few flavour concentrates some PA/loranns or others. They look/smell fine and taste test a drop on the tongue they seem fine..
I notice I have barely untouched bottles of PA mountain dew and a "lime tripler" bought from vape king Australia. Was just about to mix up a small bottle of citrusy goodness when I vaguely remember WHY I have barely touched these 2 flavours - they cracked tanks. Even though I LOVED these flavours I could only use them in cartos. Should I use it in my glass tank? or throw it all out?
I remember losing a few syringes to TFA Banana Ripe, would pull it into the syringe and it done something to the rubber inside and they would completely seize up.
From A Guide to Chemical Resistance of Polycarbonate:
When polycarbonate is attacked by a chemical it usually takes one of three forms. ... Lexan polycarbonate is affected in this way by partial solvents such as low molecular weight aldehydes and ethers, ketones, esters, aromatic hydrocarbons and perchlorinated hydrocarbons.
If your talking about TFA citrus punch don't vape that, it has vitamin e oil and is flammable. They have a second formulation "citrus punch II" that is safe
yeah.. the bottle I have is label "Mountain Dew", which was later renamed Citrus Punch because copywrite or whatever.
Dammit.. well I def won't be vaping this stuff then.. perhaps I'll keep it for baking... few drops in some cream cheese cupcake frosting might be nice. lol.
does Citrus Punch v2 taste the same?
I couldn't tell you I only have the first version, I didn't know until I was vaping citrus punch SFT at 5% and started to get dizzy and see spots and after looking more into the flavor I believe it is the vitamin e. just figured I would try and save someone else the pain, I ordered LB's mountain dew type, hopefully that works out because I really want a dew type vape
By PA I assume you mean TPA/TFA?
I'd be surprised if the concentrates are still good after 6 years, you'd have to try them.
They cracked plastic, not glass, so if you want to use them, use them. I suggest if you are concerned about the chemical makeups, to check the list in the sidebar. It's there so you can make your own mind up.
FWIW I have gobs of flavors which are 5+ years old. Some of these (mostly FW) have gone dark brown and get tossed. The majority, however, are still fine for vaping.

You haven't been around long, then. Tank crackers are a thing, and juices sold online used to have a warning if they were crackers. We should start to see cracker warnings again now, what with the rise of the pod people. It's mostly about PMMA (acrylic) and polycarbonate. If you want a good demonstration of the phenomenon, grab a CE4 or an old Kayfun with a plastic window section and throw in some of Mad Murdock's Radiator Pluid. Don't put your device in your pocket unless you really want a pocketful of anise-and-grapefruit goodness. Cinnamon, citrus and anise flavours were the worst offenders; your friendly neighbourhood DIY community recipe site should include cracker warnings on its flavour pages.
Glass/pyrex/quartz tanks aren't affected, although there are some things that will eat some synthetic o-rings. Neither is PEI (Ultem) or PEEK. POM and Teflon are resistant as well, so your drip tips will be okay if they're made of one of those plastics.
