The note presents as brilliantly clean, crisp, and cool, an olfactory sensation akin to pristine, unadulterated air after a refreshing rain or atop a desolate mountain peak. It is profoundly ozonic, carrying an expansive, almost boundless quality, often with a subtle, shimmering metallic edge that speaks of modernity and clarity. Its texture is weightless, transparent, and ethereal, like cool mist or polished glass. It possesses a high-pitched, almost crystalline luminescence, often described as embodying shades of "blue" or "white." The intensity can range from a delicate, barely-there whisper to a piercing, invigorating burst. As it evolves, it typically maintains its core fresh and clean character, serving primarily as a tenacious top or heart note, offering significant lift and projection without adding warmth or heaviness. It's the scent of spaciousness itself, devoid of overt sweetness or earthiness.
