Calone (also known as Watermelon Ketone, Calone 1951; CAS 28940-11-6) is a signature “sea-breeze” molecule in modern perfumery. Since the late 20th century, it has defined clean, airy, and mineral facets that evoke wind over saltwater and sparkling spray.

Its scent profile is distinctly marine-ozonic with a gentle salinity, unfolding crisp watermelon rind and cool cucumber nuances. The opening feels bright and breezy, followed by a dewy, translucent green body and a characteristic oceanic minerality that keeps compositions fresh yet dimensional.

In formulas, Calone boosts diffusion and “lifts” citrus–aromatic accords, polishes woods–musks with a pristine clarity, and anchors the classic aquatic/blue style. It offers solid substantivity, carrying a cooling freshness from top into the heart and prolonging the clean impression.

Calone is widely used in fine fragrance, body mists, wash and care products, fabric care, room sprays, and candles whenever a clear marine–ozonic effect is desired. It is a reliable choice for “sea breeze,” “marine fresh,” and “coastal clean” concepts, as well as minimalist, transparent creations.

Technical notes: off-white crystals with strong, diffusive odor; soluble in ethanol and fragrance oils, insoluble in water. Store cool and dry, away from light; crystallization may occur at low temperatures-gently warm to return to liquid phase before use. For fragrance use only; do not apply undiluted to skin.
