As expensive as it is, I would never use it in a wash off product. If you did want to use it in soap, best to use HO and add the oil after the cook so its not ruined by the lye.
It would probably be better in a whipped body butter.
1ml of absolute is around 30$ I wonder how many soap bars you could properly scent with 1ml. I would assume 8 x 140gr bars. So yeah I know this is some luxurious stuff.
