Ozonic notes, also known as air, aquatic, or marine notes, are designed to evoke the fresh, clean, and airy character of the atmosphere, sea breeze, or fresh rain. These synthetic notes are commonly used in contemporary perfumery to convey a sense of freshness, lightness, and purity. Ozonic notes are often found in fresh, citrus, floral, and aquatic compositions, adding a modern, crisp, and invigorating quality to fragrances.

Ozonic notes have a clean, fresh, and slightly metallic aroma with airy, watery, and almost clean linen nuances. Their scent is light and crisp, with subtle mineral and green undertones that create a sense of open air or a fresh, oceanic breeze. The overall profile is cool, invigorating, and transparent, evoking the sensation of a fresh breeze or mist. Ozonic notes enhance the brightness and freshness of fragrances, offering a crisp, ethereal quality that feels rejuvenating and pure.
