Jojoba is a shrub or small tree, Simmondsia californica, of the family Buxacea, and is a native plant of southwestern North America. It has edible seeds that contain a valuable liquid wax. Recent interest in the plant was stimulated by possibilities for using the wax during cold rolling of aluminum sheets. According to these studies, staining and viscosity deficiencies make jojoba unsuitable as a rolling oil for aluminum; however, tests are being continued to determine other possible applications.
