I used to think EOs were stronger/had more staying power scent-wise, but now I'm learning that no, it takes just as much of an (expensive!) EO to scent soap as the cheaper FOs. I am therefore now leaning toward using my EOs almost exclusively in my balms and lotions and such, as their (alleged) therapeutic qualities can really shine there. Between going through saponification and being a wash-off product, I wonder how much therapeutic benefit (beyond scent) is really left most of the time from an EO. Thoughts on this?
