Octyl cinnamate (2-ethylhexyl cinnamate) is a very mild, faintly sweet balsamic-oily material with a soft cinnamic undertone. It is largely used as a UV filter rather than for its odor, but on a blotter it reads as a low-key waxy, slightly powdery cinnamic warmth with minimal projection.AI · claude-opus-4-7

Colorless, slightly viscous liquid.
Insoluble in water, soluble in alcohol and oils.
Very mild, but sweet and tenacious, balsamic odor. The sweetness is more herbaceous-spicy than fruity, and it is often described as Opopanax-like.
This ester has been suggested for use in perfume compositions, and it has occasionally been used in heavy Oriental fragrance types such as 'Shamilar' types, where Castoreum, Opopanax and heavy-sweet wood odors are connected to rich, sweet florals with a strong emphasis upon balsamic fixative notes, also including Vanillin.
Produced by azeotropic esterification of n-Octanol with Cinnamic acid. Also by alcohol interchange reaction with Methyl cinnamate.
