Aside from contamination and precipitation, you should be fine.

I agree. The ingredients are quite stable (or have a high metastability as a chemist would call it) and can exist long under normal conditions.
...except casandra's that belong to the funniest, most interesting and imaginative (or over-imaginative?) ones, I suppose.
