I got an essential oil blend of Bergamot Grapefruit from WSP and cp'ed it about 3 weeks ago and it still smells amazing. I used moroccan red clay to see if that would hold the scent and I don't know if it was the clay or the blend of bergamot and grapefruit together. The scent is so strong that I can smell it when I walk into the laundry room (that is where all my soaps cure and sleep until bath time!) Maybe try the bergamot/grapefruit combo and throw in some clay for good measure???
