UPDATE:
My aim is to compile a list of juice and flavorings that
may cause
potential problems as far as cracking
polycarbonate tanks. Anything listed here
may cause your polycarbonate tank to crack. I just ordered 3' of polycarbonate tubing. I am going to cut the tubing and use it in my tanks to try out some questionable flavors. This way, I won't be upset if I crack one, but I'll have an answer on some of these variables.
I am primarily focused on the polycarbonate tanks, although this info can easily apply to other tanks.
I have heard good things about the new ce2's with thicker tubing.
I have also heard that the ce2 "syringe mod" can take just about anything. YMMV. There is also a wonderful thread ongoing here on how to make your own "syringe tank mod".

Also, bear in mind that different vendors may use different ingredients to make the same flavors. So, a flavored e juice you get from one vendor that is safe for yout tank may not be safe from another vendor, or vice versa. For instance, I have no trouble at all with VaporGod strawberry kiwi, but Mrs. T's strawberry shortcake can
potentially crack you polycarbonate tank. Clear as mud, huh?
Some of these are premixed juices, some are flavorings that DIY'ers use. Contributions have been made by myself and other members. So far we have:
Any juice that has:
Sour flavors
Malic acid
Citrus acid
Cinnamon like "atomic cinnamon" types, not warm cinnamon like cinnamon coffe cake, this is okay
Wintergreen juice or flavoring
TPA ripe banana flavoring
TPA honeysuckle flavoring
TPA maraschino cherry flavoring
TPA cherry blossom flavoring
TPA root beer flavoring
Mrs. T's strawberry shortcake, snickerdoodle
KBV Hummingbird nectar
mimosa(because of the orange)
cola(because of cinnamon)?
Vapor Renu Teaberry, cherry vanilla (possibly most of their flavors)
Vapor Renu Mt. Dew baha blast and Strawberry limeade
Oil based/e liquid that conains essential oils, when mixed with pg/vg, creates esters which will crack plastics
E liquids that contain triacetin, used in vg liquids to carry flavor more effectively
Vapalicious Gooey Butter Cake
Nutmeg
Clove oil
Mt. Dew flavoring
TPA Cinnamon Danish flavoring
Sassafras
Rawrvapor Hawaii Sunrise
I just noticed that Perfumer's Apprentice lists triactetin as in ingredient in some of their flavors, so be sure to check that out.
With so many folks using tanks nowadays, let's all contribute here!!
Disclaimer: These are not "bad" juices. They just have the
potential to cause cracking in tank systems using polycarbonate tubing.
