1-Nonanal is used very extensively, but
also very sparingly in volume, in perfume
formulations. Trace ambunts, often less than
0.1 %, are used in Rose, Lily, Peony, Orris,
Geranium, Citrus, Orangeblossom, Jasmin,
Tuberose, Opopanax and many other fragrance types, The aldehyde will supply very
natural "flower-wax" or "petal"-notes, and
give tremendous "lift" to a perfume.
It often
forms part of an "aldehydic base" which in
turn may form part of a topnote composition.
In flavor compositions, the aldehyde is used
for imitation Citrus, particularly Lemon and
Mandarin. Concentrations are very low, normally about 0.2 up to about 6 ppm in the
finished product.
