Safety Profile
GENERALLY SAFEWhat Does Linalyl cinnamate Smell Like?
Linalyl cinnamate opens with a bright, floral-lavender character that gradually reveals a warm cinnamon-like spiciness. As it dries down, the scent develops a soft balsamic sweetness reminiscent of antique wood polish. The evolution is like watching sunlight move across a spice market – first hitting the flower stalls, then warming the cinnamon bark, finally lingering on well-oiled wooden counters.

Chemistry, Properties & Perfumer Guide
The Chemistry
Linalyl cinnamate is an ester formed from linalool and cinnamic acid. While found in some essential oils, commercial production typically involves esterification of these two components. The synthetic route allows for precise control over stereochemistry and purity. As an ester, it’s relatively stable but can hydrolyze under extreme pH conditions.
