<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">oil used in cosmetics</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for jojoba that I've seen before include "Seedy desert native" , "desert plant" , "North American shrub whose oil is used in cosmetics" , "plant oil" , "Cosmetic oil" .)
