These and the rest of your comment are wonderful details,
@not_ally . I really appreciate them. What I want to end up with eventually is a list of fairly simple fragrances that stick in cold process soap--
@Mobjack Bay 's links are going to be helpful too I think.
Some of the scents I know I want are:
* litsea
* orange, if there is one that sticks
* other citrus, if orange doesn't stick
* rosemary
* ginger (which is absolutely bonkers expensive but I still want to have it for my fanciest moments)
* cedarwood
* something floral that isn't lavender
* fir, pine, spruce, something in that family
* salt or ozone or petrichor
