The unscented one is referred to as RBD coconut oil. That stands for:
They need to do this because the coconut is often old, black and rancid when they make this type of oil. It needs to go through many steps to make it usable as a food.
For this reason I would never buy the unscented oil (what a great marketing gimic, to call it unscented). The scented ones are made using fresh coconuts and are much better for you.
