IMO, I would not waste Jojoba in Soap. The qualities will change drastically and you will not get any benefits from it as you would when rubbed directly on the skin. Avocado in soap however does make the suds more richer, so i would use that over jojoba in soap. edit: after all, the only thing you really can get from a soap, is a rich, creamy lather that leaves you smelling good and will not irritate or leave your skin dry. If you are trying to obtain vitamin and nutrients out of oils, then you need to preserve those for use in lotions and creams.
