Запах

At 1% the odour is waxy, aldehydic and citrus, with a fresh, slightly green lemon-peel nuance and a cucumber fattiness. Other descriptions give an orange-rose odour, and a floral, waxy, green one. Another describes a strong, sharp, fatty odour with a rose-orange note. Nonanal is less metallic or soapy than shorter-chain aldehydes such as hexanal and has a more rounded citrus tone.

Докладно

Nonanal has the chemical formula C9H18O, written CH3(CH2)7CHO. Its CAS number is 124-19-6.

Nonanal is found in at least 20 essential oils, including rose oil, citrus oils and several species of pine oil. It also occurs in plant sources such as citrus peels, cassava and rice.

Nonanal is insoluble in water but soluble in alcohol, fixed oils and propylene glycol. Commercial material is specified at 92 to 100% assay, with 2-methyloctanal at 4 to 8% as a secondary component.

Nonanal is among the key products of ozone reacting with many indoor building and furnishing materials.

У парфумерії

Nonanal is used very extensively in perfume formulations, but in very small volume. Trace amounts, often less than 0.1%, are used in rose, lily, peony, orris, geranium, citrus, orange blossom, jasmine, tuberose, opopanax and many other fragrance types. It supplies natural flower-wax or petal notes and gives a perfume great lift. It often forms part of an aldehydic base, which in turn may form part of a top-note composition. At higher levels it is an important ingredient in citrus and rose notes, and in trace amounts it adds bloom to a wide range of fragrance types. It boosts freshness in floral compositions such as rose and jasmine. In combination with citrus blends, it enhances the natural character of the fragrance and makes it more diffusive. In flavours it gives an intense orange character to citrus and other flavours.
