A soft, powdery iris/violet-like note with a warm woody undertone. Neo-Irones is a Firmenich blend of iso-methyl ionones and irone-type molecules that gives a natural, buttery orris character — less sharp than pure methyl ionone, with a suede-like smoothness that develops a delicate powdery drydown.AI · claude-opus-4-7
