n-Octyl caprylate (octyl octanoate) is a fatty ester used primarily as a cosmetic emollient and diluent rather than an odorant. On a blotter it is nearly odorless, with at most a very faint oily-waxy background note. It contributes almost no olfactory character to a formula.AI · claude-opus-4-7

Colorless oily liquid.
Practically insoluble in water, soluble in alcohol and oils.
Weak, but persistent and sweet-herbaceous, almost tea-like odor.
The taste in concentrations below 5 ppm is oily-fruity, sweet, mildly green or herbaceous. Higher concentrations tend to produce bitter-herbaceous and unnatural notes.
This ester has been suggested for use in perfume compositions, but the author finds that there is no important use of it, nor any demand for this ester in perfumery.
It finds limited use in flavor compositions, mainly in Citrus complexes, Cherry, Grape, Pineapple, Plum and other fruit imitation flavors.
Produced by azeotropic esterification of n-Octanol with Octanoic acid.
