How’s it going Jame? As you know, oud oil is a mixture of a bunch of things and is not just 1 molecule. Probably not even just 1 type of oil. I’ve had oils start to solidify like olive oil does sometimes if you put it in the fridge. Particularly hindis and in the winter. It will melt again right away if you hold the vial.
I don’t think that just because something smells like perfume that this means it’s fake. There are many common perfume “ingredients” that are either meant to smell exactly like oud oil or are molecules that are found in oud oil.
Oud has molecules in it that are responsible for the scent of berries? As well as some that are common in florals, vetiver, sandalwood. It’s a complex product. Really a “perfume” in its own right.
