Quick Clot expiration

[Arklatex]

I was looking through some of my stuff and noticed that several of my Trauma Kits were past the expiration. Looking online the quick clot website says not to use expired products. The same site claims the active ingredient is kaolin. Apparently it is a mineral and inorganic. Other sites claim *opinions* the stuff lasts forever so long as it's sealed and in a stabil temperature. Anybody know what the shelf life, if any, is for this stuff?
