Oxygen Notes

Oxygen Notes are abstract, synthetic accords crafted to evoke the sensation of clean air, atmospheric freshness, and expansive openness. Not a scent in the literal sense—since oxygen is odorless—these notes are created using ozonic and marine molecules that mimic the crispness of high-altitude air, the purity of wind-swept coastlines, or the chill of freshly opened space. In fragrance, Oxygen Notes deliver a distinct airy lift, often described as cool, slightly metallic, watery, or effervescent. Used primarily in top notes, they bring a transparent brightness and a sense of lightness that modernizes florals, invigorates citruses, and adds a spacious clarity to the overall composition.

History & Production: First popularized in the 1990s with the rise of aquatic and ozonic fragrances, Oxygen Notes are typically constructed from synthetic molecules like Calone, Ozonal, Aldehydes, or Iso E Super in low concentrations. These materials are used to simulate the scent of oxygen-rich air after a thunderstorm, or the rush of wind across sea cliffs. While sometimes labeled as “ozone” or “air accord,” Oxygen Notes are prized in contemporary perfumery for their ability to add breathability, modernity, and serenity, especially when paired with marine accords, citrus, white florals, or aromatic herbs. They create a feeling of weightless clarity, like a deep, refreshing breath in a wide open landscape.
