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 geranylgeranyl of natural origin + phenylacetic acid from petrochemical synthesis0.56Geranyl fragment C10H17O 153.2/272.4 = 0.56.

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

How we scored it

Geranyl Phenylacetate C18H24O2 272.4 Da: geranyl fragment C10H17O 153.2 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 geranyl 0.56, 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

Geraniol (natural or synthetic) esterified with petrochemical phenylacetic acid.

In plain English

A rose-honey fragrance ingredient made by combining a synthetic terpene alcohol with a petroleum-derived acid. It is produced in a factory, not isolated from rose oil.
