Calone

Calone (methyl benzo dioxepinone) is a synthetic molecule developed by Pfizer in 1966 that delivers a marine, aquatic, iodized olfactive profile, founding the marine-aquatic family in modern perfumery (Wikipedia EN, accessed 2026-05-27).
Also known as: Calone 1951, watermelon ketone, molécule marine (FR), marine accord

Definition

Calone (also written Calone 1951, trade name referencing its patent number; IUPAC: 7-methyl-2H-1,5-benzodioxepin-3(4H)-one) is a synthetic molecule originally developed by Pfizer for pharmaceutical research in 1966. Perfumers discovered its extraordinary marine-aquatic-iodized character in the 1980s. Its olfactive profile is marine-aquatic, iodized, slightly floral, fresh melon (Wikipedia EN, accessed 2026-05-27).

Calone remained commercially obscure until Yves Tanguy used it in New West for Aramis (1988), then Jacques Cavallier deployed it as the signature of L'Eau d'Issey for Issey Miyake (1992), which launched the marine-aquatic olfactive family (Fragrantica, accessed 2026-05-27).

Technical detail

Calone is extremely powerful: 0.01 to 0.1 % suffices to sign a composition. Above 0.5 % it becomes overwhelming and rubbery. Pricing ranges from approximately 220 to 380 euros per kilogram (2026). It teaches a textbook lesson on dosage at ISIPCA: a molecule that creates an entire olfactive family through its uniqueness (Basenotes wiki, accessed 2026-05-27).

Calone belongs to the captive molecule history: originally studied for pharma applications, repurposed by perfumers after recognizing its olfactive uniqueness. It demonstrated that a single synthetic could define a decade of fragrance output.

Examples

Key compositions using Calone:

  • L'Eau d'Issey (Issey Miyake, 1992, Jacques Cavallier): the founding marine, Calone at its most transparent and floral.
  • Acqua di Giò (Giorgio Armani, 1996): marine-fougère with Calone in the heart, dominant in 1990s masculine perfumery.
  • Cool Water (Davidoff, 1988): earlier deployment of the marine register, precursor to the aquatic wave.
