Calone was an accident in a drug lab.
In 1966 chemists at Pfizer, led by J. J. Beereboom, were working on benzodiazepine-related structures, the chemical family behind tranquillisers. One compound they made, 8-methyl-1,5-benzodioxepin-3-one, turned out to be no use as medicine and remarkable as a smell. It went into the books under the internal code Calone 1951.
What it smells of is sea air over cut melon. Ozonic and cold on top, a green watermelon-rind edge underneath, a faint floral background behind that. It is also extremely loud. Perfumers usually keep it at or below 0.8 per cent, because above that it will take over a formula entirely.
For two decades almost nobody used it. The turn came in 1989, when Aramis New West for Her was built with calone at 1.2 per cent, an unheard-of dose at the time. The aquatic decade followed: CK Escape, Kenzo pour Homme, Hugo, and then in 1996 Giorgio Armani's Acqua di Giò pour Homme, created by Alberto Morillas with Annick Menardo and Christian Dussoulier, which put calone in the heart next to sea notes and jasmine and became one of the best-selling men's fragrances ever made.
Then Pfizer's patent expired and the molecule went everywhere. It reappeared under other trade names, Oceanone, Aquamore, Calone 161, and moved out of fine fragrance into air freshener, fabric softener and washing-up liquid. By the end of the decade the public had been thoroughly overdosed, and houses started dialling it back.
It never actually left. Modern fresh and marine fragrances still run on calone, at lower doses and blended with ambergris-style molecules to soften the ozone. So when a bottle promises you the sea, this is the molecule doing the promising, and no part of it has ever been near a beach.
The most famous calone fragrance is also the one we get asked for most. Aqua De Gio is our take on Armani Acqua di Giò, and Invicto, our take on Paco Rabanne Invictus, runs a similar marine accord over grapefruit. Both are UK-made sprays at 35% concentration.
