Lifespan of leather balm, gum tarcaginth, and dye

[crimsonking]

So I was going through some old leather stuff and found I still had some brown dye, leather balm and gum tarcaginth (spelling?).  My question is I know they are at least 5-7 years old are any of these still good?  Some of them are still in the plastic bag they were mailed to me in and unopened while others have been open but had lids on the the whole time.
