Heat, light, especially UV. Keep developers in cool, dark place.
Incidentally, speaking of 2,4 disubstituted benzophenone (from the
dichroic fog thread), this agent is commonly added to cosmetic
products to block UV during storage, to improve the packaging design
while securing keeping property. Whether adding it to XTOL is
beneficial? Maybe.
