I am totally addicted to ZUM goatmilk Mint soap, they say it is only spearmint essential oil that makes the awesome fragrance, but I just don't know, I made some and used spearmint with olive, coconut and palm with some castor (just like ZUM does) and mine wasn't as awesome smelling as theirs... I have GOT to make some like theirs, I cannot afford to keep buying those small bars for $4 from the local health food store...any suggestions? after a month or so , mine had an "off" smell,,,used all new oils, don't know what the problem was...
