High Altitude French Lavender was a best seller for my wholesale customer in Mobile for 10 years.
MMS Tahitian Vanilla flew off the table at an event I did in my early days in an office building. It discolors to fudge brown.
I named it "
Bora Bora".
50/50 Lavender/Anise sold out when a gal bought a bar on her lunch hour and came back at 4 PM to take the 5 remaining bars.
Rose Geranium EO is fresh, clean, unisex, and unique because not many soapers use it as a single note fragrance. Because it is expensive, consider blending it with a folded orange EO.
NOTE:
Oakmoss (10%) can be used to anchor most single note EOs at 1-5% of the blend to "stick" the scent (i.e. longer lasting) in soap. It is known to be a "sensitizer" if you use too much but it is considered, not only safe, but effective at that low % of use.
