ALDEHYDE C9 (NONYL ALDEHYDE) – aldehydic, waxy, floral note with hints of lemon peel, rose petals, and green cucumber

A waxy, citrusy, floral, green, rose, orris scent, with a fresh, slightly greenish lemon zest nuance and a cucumber-like richness. Used in floral and citrus blends. A classic aldehyde note: waxy, citrusy, floral, and green.
At higher concentrations, it is an important ingredient in citrus and rose notes. In small amounts, it adds intensity to a wide range of fragrances. It is one of the "classics" in the fatty aldehyde family. It adds freshness to floral compositions, such as rose and jasmine, and also lends warmth and elegance. When combined with citrus blends, the natural character of the perfume is enhanced and becomes more diffused. This aldehyde is used very widely in perfumery compositions, but always in moderate quantities. Residual amounts, often less than 0.1%, are used in rose, lily, peony, iris, geranium, citrus, orange blossom, jasmine, tuberose, opopanax, and many other fragrances. The aldehyde imparts very natural "floral wax" or "petal" notes and gives the perfume an incredible "elevation." It is often part of the "aldehyde base," which in turn can be found in top note compositions. It solidifies in the cold, liquefying again at a temperature of 6°C.
A very strong and diffused fragrance, rich and floral, with a medium-lingering waxy note. With proper dilution, the rich notes become more pleasant, floral-waxy, more rosy and sweet, fresh like neroli.
At concentrations below 5 parts per million, it has a refreshing, citrusy, and waxy taste. This aldehyde is widely used in perfumery compositions, but always in small quantities. In food flavorings, the aldehyde is used to imitate citrus fruits, especially lemon and mandarin. The concentration in the finished product is very low, typically 0.2 to 6 parts per million.
