The note possesses an intensely pungent, sulfuric, skunky, almost overwhelmingly green and onion-like aroma. It is incredibly diffusive and potent, requiring extreme dilution even for experienced perfumers. At high concentrations, it is repulsive, but when carefully managed it can impart a surprising depth and complexity, adding a vegetal, almost savory quality. Projection is enormous, and longevity is exceptionally tenacious.
