The note unfolds with an immediate, assertive presence, a dense, viscous olfactive texture that is both slick and slightly granular. It presents as a heavy, dark oil, with dominant facets of mineralic petroleum, a distinct metallic tang reminiscent of hot steel or iron filings, and a subtle underlying warmth that suggests friction and industrious work. There's a greasiness, not of butter or fat, but of inert, non-organic lubrication, often accompanied by a faint, almost electrical ozone or burnt rubber nuance at its heart. Its projection is typically strong and linear, anchoring compositions with an unwavering industrial tenacity. As a base note, it possesses exceptional longevity, clinging to the skin or fabric for hours, gradually softening into a muted, earthy-metallic hum, sometimes revealing a surprising, faint sweetness akin to creosote or asphalt after a summer rain. It lacks the typical aromatic lift of a top note, emerging instead as a foundational, grounding element.
