In the realm of specialized chemicals, understanding the properties and applications of key ingredients is fundamental for both industrial processes and creative product development. Watermelon Ketone, known by its CAS number 28940-11-6 and chemically as 8-methyl-1,5-benzodioxepin-3-one, is a prime example of such an ingredient, widely recognized for its dual utility in fragrance creation and industrial applications.

Chemically, Watermelon Ketone is a synthetic organic compound. Its empirical formula is C10H10O3, with a molecular weight of 178.18 g/mol. It typically presents as a white crystalline powder with a melting point in the range of 38-40°C. Its stability is good when stored in a cool, dark, and dry place, protected from heat and light, ensuring its efficacy over time. High purity, often exceeding 99.0% by HPLC, is a critical specification for its use in demanding applications.

The most notable characteristic of Watermelon Ketone is its potent and unique olfactory profile. It is characterized by fresh, watery, clean melon, green, marine, and ozone notes. This distinctive scent makes it an invaluable component in the perfumery industry, particularly for creating aquatic, oceanic, and airy fragrance compositions. It has been a foundational ingredient in defining the marine fragrance trend since the 1990s, adding a signature freshness and diffusion to countless popular perfumes.

Beyond its significant role in perfumery, Watermelon Ketone also serves important industrial functions. It is utilized as an analytical standard for quality control and research purposes. Furthermore, its properties make it suitable for use as a solvent and humectant in the manufacturing of various products, including plasticizers, pharmaceuticals, polyester resins, and polyurethane resins. This versatility underscores its importance across different segments of the chemical industry.

For businesses seeking to purchase Watermelon Ketone, understanding its safety profile is also essential. While generally considered safe for use in fragrance applications within recommended levels (e.g., up to 0.5% in fragrance concentrate as per IFRA guidelines), it is classified as harmful if swallowed and can be irritating to skin and eyes. Proper handling, adherence to safety data sheets, and responsible disposal are therefore crucial.

Sourcing high-quality Watermelon Ketone from reliable manufacturers is key to ensuring product integrity and cost-effectiveness. Suppliers in China, such as ourselves, specialize in producing this chemical at high purity levels and offer competitive pricing for bulk orders. When procuring, buyers should look for suppliers who can provide comprehensive technical data, consistent quality, and efficient logistics, making the purchase process smooth and reliable.

In summary, Watermelon Ketone (CAS 28940-11-6) is a multifaceted chemical with a distinctive sensory appeal and practical industrial applications. Its role in modern fragrances and its utility in various manufacturing processes highlight its importance in the chemical market. Engaging with a trusted manufacturer ensures access to a premium product that meets exacting standards.
