The note, primarily derived from the resin of the sweetgum tree (often referred to as Styrax or Storax in perfumery), presents a multifaceted olfactory profile. It opens with a warm, rich balsamic sweetness, reminiscent of vanilla and benzoin but with an underlying leathery, slightly smoky complexity. There's a subtle spicy facet, often suggesting cinnamon or clove, alongside a soft, creamy woodiness. Occasionally, depending on the extraction and processing, one might detect a faint green, almost camphoraceous or medicinal edge, especially if components of the leaves or bark are present. Its texture is smooth, almost viscous, with a gentle, enveloping projection that settles into a tenacious, comforting warmth. It functions predominantly as a robust heart or base note, grounding compositions and providing exceptional longevity.
