I know that there's a lot of different types of things that fall under the 'wax' umbrella, but they all seem, eventually, to various degrees, to 'dry out'.

For example, this other SE question (and several answers) discuss the wax gasket in a toilet drying out.

I assume (perhaps mistakingly!) that this is not actually a loss of water molecules -- so what is really happening?

    $\begingroup$ Many waxes have a broad range of chain lengths. As the shorter chains disappear or cross link you can see changes in mechanical properties. $\endgroup$ – Jon Custer Feb 7 at 16:24
