Is Neryl Isobutyrate natural?

It depends. Nerol is sold both as an essential-oil isolate and as a synthetic; isobutyric acid is petrochemical, as for the site's other isobutyrates.

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 + isobutyric acid from petrochemical synthesis0.68Neryl fragment C10H17O 153.2/224.3 = 0.68.
syntheticneryl and isobutyric 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 Isobutyrate C14H24O2 224.3 Da: the neryl fragment C10H17O 153.2 Da is natural only from a natural source; the isobutyric acid fragment 71.1 Da is petrochemical in every commercial route. Routes: natural neryl 0.68, 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 isobutyric acid.

In plain English

A fruity, rose-like fragrance ingredient made by combining nerol, a floral plant terpene, with isobutyric acid; the nerol may come from essential oils or be made synthetically.
