Calone® presents a cool, watery profile combining marine ozone with a soft honeydew–melon facet. The aroma is transparent and expansive rather than sweet, with a lightly metallic, ozonic edge. At low levels it reads fresh and clean; at higher levels it becomes distinctly aquatic and dramatic.

Calone® functions as a top-to-heart note or freshness modifier, shaping space and lift.

Recommended concentration: 0.02–2% (very potent; start low)

Particularly effective in:
Aquatic and marine fragrances
Fresh florals and citrus structures
Modern aromatic and “clean” profiles

Blends well with:
Citrus notes (bergamot, lemon, grapefruit)
Muguet and fresh floral materials
Musks, Iso E–type woods, and light ambers

Supplied as crystaline powder and typically pre-dissolved in alcohol (e.g. 10%) before use for accurate dosing and ease of blending

Suitable for non-perfumery applications such as candles and home fragrance at low levels

Small dosage changes noticeably affect aquatic intensity and diffusion.
