Is Linalyl Isobutyrate natural?

It depends. Linalool has both essential-oil and petrochemical sources; isobutyric acid used is essentially always petrochemical (oxo-synthesis).

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
naturalessential-oil linalool + petrochemical isobutyric acid0.68~20%
syntheticpetrochemical linalool + petrochemical isobutyric acid0.00~80%, dominant
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Ester of linalool+isobutyric acid. Natural-linalool route: 153/224=0.68. Synthetic-linalool + petrochemical isobutyric acid: 0.0. Headline shows the best route (0.68), as for every route-dependent entry on the site.
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

Most commercial linalyl isobutyrate is made from synthetic, petrochemically-produced linalool and isobutyric acid. A smaller share uses essential-oil-extracted linalool.

In plain English

A fruity fragrance ingredient made by joining linalool with isobutyric acid. It is mostly produced synthetically, though a version using naturally-extracted linalool exists.
