ALDEHYDE C18 (gamma-nonalactone) – lactonic, creamy and fruity note with hints of coconut, warm milk and ripe peach

Colorless or very pale straw yellow, oily liquid.
Practically insoluble in water, soluble in alcohol and oils.
Creamy, coconut-like fragrance, delicately fruity (when heavily diluted) and floral-musky with excellent persistence. A powerful, widely used lactone, reminiscent of dried coconut. It strikes a balance between coconut and peach notes.
Creamy and nutty flavor at a concentration of approximately 50 parts per million, delicately fruity and sweet at concentrations of 1 to 5 parts per million.
This substance is one of the most commonly used lactic acid compounds in perfumery and flavorings. Its applications range from the finest luxury perfumes to the cheapest odor maskers, from gardenia floral bases to coconut candy flavorings, and more. Its intense sweetness and long-lasting effect are often combined with undecanolide (also known as C-14 aldehyde) in gardenia, tuberose, honeysuckle, plumeria, jasmine, and many other heavy floral compositions. Modern perfumes with musky and lactone accents may include this compound, creating a fixative effect of overwhelming sweetness, while new versions of oriental perfumes can be created using sandalwood, styrax, and this lactone as a base. Perfumers often underestimate its potency (unless they have fragrance experience), and the lactone can stand out strongly in perfumes, unpleasantly dominating the aroma.
In flavorings, lactone finds an even wider application and often at much higher concentrations.
In addition to coconut, this material is used to imitate almond bitterness, fruit blends (fixative), berry complexes, nut variations, American cherry flavoring, etc. The concentration in the finished product can range from 10 to 50 parts per million.
