Couple of loose notes here...
Fatty chains hanging out on a razor are prone to oxidizing because, remember, they're also in an atmosphere that is about 21% oxygen.
There have been some reports of camellia oil polymerizing. As Onimaru says, not good for long-term storage unless you're taking the blade out and re-oiling it. I assume that during the re-oiling, the old oil gets wiped away.
Oils formulated for firearms are going to be the best bet, I think. They're designed to spread thin and not turn to gunk over time.
