Since its discovery, the world of fragrance has been periodically transformed by the introduction of groundbreaking aroma molecules. Among the most influential is Watermelon Ketone, also known commercially as Calone, a synthetic compound identified by the CAS number 28940-11-6. This molecule single-handedly defined the aquatic and marine fragrance category that surged in popularity in the 1990s and continues to be a cornerstone of modern perfumery. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer of specialty chemicals, is proud to produce high-purity Watermelon Ketone, empowering creators across the globe to innovate with this iconic scent.

The Olfactory Revolution of Watermelon Ketone

First synthesized in the 1960s, Watermelon Ketone, or more formally 7-Methyl-2H-1,5-benzodioxepin-3(4H)-one, did not see widespread use until the late 1980s. Its emergence marked a significant departure from the traditional floral, oriental, and chypre fragrance families. It delivered something entirely new: an intensely fresh, diffusive, and powerful 'sea-breeze' note. The scent is complex and evocative, characterized by several facets:

Marine & Ozonic: The primary and most recognizable quality is a fresh, airy, and slightly salty scent that strongly evokes the ocean shore and ozone.
Watery & Fruity: As its name suggests, it possesses a distinct aqueous and fruity undertone, reminiscent of fresh-cut watermelon or melon rind. This quality adds a juicy, refreshing crispness.
Floral & Green: Beneath the dominant marine notes lie subtle floral and green overtones, which provide lift and complexity, often compared to lily-of-the-valley.

This unique profile made Watermelon Ketone an indispensable tool for perfumers aiming to create scents that felt clean, invigorating, and expansive. It became the signature note in numerous iconic fragrances, defining a generation of perfumery and establishing the 'aquatic' or 'oceanic' genre as a global phenomenon.
