Is Cinnamyl Isovalerate natural?

It depends. Cinnamyl alcohol and isovaleric acid each have natural (balsam, fermentation) and dominant petrochemical (benzaldehyde, oxo-process) commercial routes.

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.

RouteFeedstockNOIShareNotes
synthetic esterification (dominant)petrochemical cinnamyl alcohol (ex-benzaldehyde) + oxo-process isovaleric acid0.00~90%
naturalstorax/balsam-derived cinnamyl alcohol + fermentation isovaleric acid1.00~10%
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

C14H18O2, 218 Da: cinnamyl alcohol + isovaleric acid ester. Both fragments have minor natural (balsam/fermentation) and dominant petrochemical (benzaldehyde/oxo) routes; not averaged. Headline shows the best route (1.00), as for every route-dependent entry on the site.
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

Predominantly made by esterifying petrochemical cinnamyl alcohol with petrochemical isovaleric acid. A minor natural route uses balsam-derived cinnamyl alcohol and fermentation isovaleric acid.

In plain English

A fragrance ingredient with a sweet, fruity-balsamic smell, made by combining two smaller molecules. It's usually produced synthetically, though a natural version exists made from plant resin and fermentation.
