Does Emofin Powder go bad?

Found an old, unopened pack of Emofin (over 13 years old for sure). Use or dispose? Any experiences?

(there was a url link here which no longer exists)
See post 182, part A is probably PPD plus Metol with some Bisulfite preservative, it should keep if not exposed to air but only a small wager is warranted.

Thanks for the answer. I guess I won't risk it right now then, because the bags are really only paper... Maybe when I have an unimportant test film at hand...
