Ethanol 96% And Propylene Glycol Storage Conditions

[whatevr]

Finally going to pick up a bottle of Ethanol 96% for preparing RU and other topicals.
Wondering how and where it should be stored, or does it matter?
Room temperature, fridge, in darkness?

Also, same question for propylene glycol.

Thanks

Supposedly RU gets degraded by light and air so i store the powder in the freezer completely sealed with aluminum foil and ziploc (maybe overkill but w/e) and i store my 4 day solution in a dark cabinet. Ethanol can be left at room temp i'm pretty sure and my bottle of PG says to store it in a cool, dry well ventilated place
