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

Cinnamyl Phenylacetate C17H16O2 252.3 Da: cinnamyl fragment C9H9O 133.2 Da is natural only from an essential-oil, balsam or turpentine source; the phenylacetic acid fragment 119.1 Da is petrochemical in every commercial route. Routes: natural cinnamyl 0.53, 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.
