Is Linalyl Cinnamate natural?

It depends. Linalool and cinnamic acid both have natural and synthetic sources, so the ester is route-dependent.

Why the score varies

This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.

Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Linalyl Cinnamate C19H24O2 284.4 Da: linalyl fragment C10H17O 153.2 Da is natural only from an essential-oil, balsam or turpentine source; the cinnamic acid fragment 131.2 Da is natural only when the acid is a fermentation or natural isolate. Routes: natural linalyl and natural cinnamic acid 1.00, natural linalyl 0.54, synthetic 0.00. Headline shows the best route.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Linalool (essential-oil isolate or synthetic) esterified with cinnamic acid (balsam or Perkin synthesis).

In plain English

A sweet, balsamic fragrance ingredient made by joining linalool with cinnamic acid. It is usually produced synthetically, although a version using naturally-extracted linalool exists.
