Safety Profile
GENERALLY SAFEWhat Does Ocimenyl acetate Smell Like?
Ocimenyl acetate opens with a crisp, dewy greenness reminiscent of crushed tomato leaves and freshly cut herbs. The heart reveals a delicate fruity nuance akin to underripe pears, floating above a clean woody-amber base. Over time, it settles into a transparent muskiness that amplifies adjacent floral materials without overpowering them.
Chemistry, Properties & Perfumer Guide
The Chemistry
Ocimenyl acetate is an ester derived from ocimenol, a monoterpenoid alcohol. Industrially produced via esterification of ocimenol with acetic anhydride under controlled conditions. The synthetic route ensures consistent quality and avoids natural variation. Molecular structure features an acetate group attached to a branched terpene backbone, contributing to both volatility and tenacity.
