The note, when evoked, presents a piercingly sharp, almost metallic, and intensely clean aroma. It carries a distinct, somewhat abrasive quality, often described as sterile, bright, and invigorating, yet with an underlying chemical sharpness that can prickle the nose. Its texture is more akin to a sensation than a tactile feel – it's cool, almost 'wet' and transparent, with an effervescent quality that tingles. The intensity is typically high upon initial perception, radiating with a singular, unmistakable clarity. It projects quite strongly, announcing its presence distinctly, but its longevity as a primary 'note' is usually fleeting, existing more as an impactful top-note effect or a sharp, transient heart accord that swiftly transitions. It doesn't evolve in a traditional sense; rather, it either dissipates quickly, leaving a clean impression, or recedes into the background to support other aquatic or aldehydic elements.
