Route-dependent · ISO 16128

Is Neryl Propionate natural?

It depends. Nerol is route-dependent; propionic acid is petrochemical, so even the natural-nerol route keeps a petrochemical propionyl group. Same ruling as Neryl Formate.

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 nerylneryl of natural origin + propionic acid from petrochemical synthesis0.73Neryl fragment C10H17O 153.2/210.3 = 0.73.
syntheticneryl and propionic 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

Neryl Propionate C13H22O2 210.3 Da: the neryl fragment C10H17O 153.2 Da is natural only from a natural source; the propionic acid fragment 57.1 Da is petrochemical in every commercial route. Routes: natural neryl 0.73, 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

Nerol (essential-oil isolate or synthetic) esterified with petrochemical propionic acid.

In plain English

A floral, fruity fragrance ingredient made from nerol (a rose-like terpene alcohol) and propionic acid. Used purely to add scent to cosmetics and personal care products.
