I finished a move and had my powder supply stored in my garage in Florida for about a year. I was starting a new project that called for some Vitavuori N133 and was happy that I had an old jug of it.
I dreaded finding a strong smell coming from the mostly empty 8lb factory container (maybe 1 lb left). It smelled sharp - something like either chlorine or ammonia. I dumped the powder in the toilet and flushed it thinking all is well. I started filling the empty jug with water and a brownish / yellowish vapor started coming out. It's unclear whether it was powder in suspension or some reaction with the water. I immediately sealed the container and took it outside. I may have inhaled a little. Even though I don't have a cough, my lungs don't exactly feel good.
When I inspected the cardboard box that the powder was stored in, I found it slightly discolored and brittle. It seems pretty clear to me now that vapors escaped and were degrading the cardboard. The label confirmed that the powder was from 2004.
I strongly suggest inspecting old batches of powder and keeping them stored somewhere where they can't cause damage (not inside the house!).
