I would still freeze the oil if there isn't room in the refrigerator for it
They suggested best practice is to keep it at 50* F rather than freezing it. If there is no need to freeze it I wouldn’t personally do so.
Agreed. If there's room in the refrigerator, it's better off there.
I suspect that some damage may be done to flavour components of the oil for consumption, and there's something niggling at the back of my mind about increasing or triggering oxidation (by freezing and thawing), but for the life of me I can't remember what the context of that was.
But for soaping? It might be a useful solution for bulk purchases. I'm going to have a closer look at the idea and see if I can find out a little more about the physical changes to the oil from freezing
