1,3-Nonanediol acetate (mixed esters) (CAS 1322-17-4) — Green Middle Note Fragrance Ingredient
1,3-Nonanediol acetate (mixed esters)
CAS 1322-17-4
What Is 1,3-Nonanediol acetate (mixed esters)?
1,3-Nonanediol acetate is a synthetic fragrance ingredient used in perfumes and personal care products. It contributes fresh, green, and slightly fruity nuances to formulations. This molecule helps create modern, clean scent profiles in body washes, deodorants, and fabric softeners where a long-lasting freshness is desired.
Safety Profile
GENERALLY SAFEWhat Does 1,3-Nonanediol acetate (mixed esters) Smell Like?
1,3-Nonanediol acetate presents a crisp, dewy green character with subtle melon-like undertones. The opening is fresh and slightly aqueous, reminiscent of cucumber skin or young bamboo shoots. As it develops, a soft muskiness emerges, lending body without heaviness. The dry-down reveals a clean, almost laundry-like quality with exceptional tenacity on fabric. Its odor profile bridges fruity freshness with woody-musky depth, making it versatile for modern green-floral compositions.

Chemistry, Properties & Perfumer Guide
The Chemistry
1,3-Nonanediol acetate belongs to the ester class, synthesized through esterification of 1,3-nonanediol with acetic acid. The mixed esters form a complex of positional isomers that influence its odor profile. While purely synthetic in commercial use, related structures occur naturally in some fruits and vegetables. The acetate group enhances volatility compared to the parent diol, while the nine-carbon chain provides optimal hydrophobicity for fabric substantivity.

Odor & Flavor
| Functional Groups | esteralcoholether💻 RDKit |
| “The title material is intended to be a Jasmin base material. It can introduce the oily-herbaceous undertones, characteristic of Jasmin absolute, but not available from one single chemical. It is used very widely for that purpose at concentrations from 1% up to 5% or in exceptional cases higher. It is very popular in soap perfumes where its stability and diffusive power increase the "odor value" of the soap fragrance.”📖 Arctander | |
| 1,3-Nonanediol acetate, mixed esters has an intense, floral odor reminiscent of jasmine. -📖 Fenaroli | |
Flavor Notes (Arctander)
| “This material is also used in flavor composi- tions, and its effect in berry complexes or fruit blends is quite interesting. The concentration is usually very low, because it is a powerful flavor, perceptible well below 1 ppm. From 0.3 to 1.5 ppm is normal in finished products.”📖 Arctander |
