I mean plenty of things would work. Even if something is soluble in the solution going into solution doesn't mean breaking chemical bonds but that the objects themselves prefer to interact with the solvent not other objects.

So long as your container is chemically bonded throughout like say a perfectly crystalline cut diamond container (fancy I know) it would be fine. The solvent wouldnt eat through the diamond.

Also you could feeeze the solvent.

The freezing is a good strategy though manufacturing might still be an issue.

You could always make an easily convertible "precursor" to store and sell instead. Sorta a "just add water" (or air, or what-have-you). Or some 2 part compound
