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
natural phenethylphenethyl of natural origin + tiglic acid from petrochemical synthesis0.59Phenethyl fragment C8H9O 121.2/204.3 = 0.59.
syntheticphenethyl and tiglic acid both from petrochemical synthesis0.00No natural carbon.
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Phenethyl Tiglate C13H16O2 204.3 Da: the phenethyl fragment C8H9O 121.2 Da is natural only from a natural source; the tiglic acid fragment 83.1 Da is petrochemical in every commercial route. Routes: natural phenethyl 0.59, 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

Phenethyl alcohol (rose-oil or fermentation grade, or benzene + ethylene oxide) esterified with synthetic tiglic acid.
