I believe the answer is:
odourless
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">unscented</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 odourless that I've seen before include "devoid of smell" , "Without so much as a whiff" , "having no hint of whiff" , "without bouquet" , "Unscented" .)
