Is Isoeugenyl Acetate natural?

It depends. Isoeugenol is route-dependent on the site (clove-oil eugenol or guaiacol synthesis); the acetyl group is petrochemical.

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 isoeugenylisoeugenyl of natural origin + acetic acid from petrochemical synthesis0.79Isoeugenyl fragment C10H11O2 163.2/206.2 = 0.79.

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

How we scored it

Isoeugenyl Acetate C12H14O3 206.2 Da: isoeugenyl fragment C10H11O2 163.2 Da is natural only from an essential-oil, balsam or turpentine source; the acetic acid fragment 43.0 Da is petrochemical in every commercial route. Routes: natural isoeugenyl 0.79, 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

Isoeugenol (isomerised clove-oil eugenol, or synthetic from guaiacol) acetylated with acetic anhydride.

In plain English

A fragrance ingredient with a spicy, floral, clove-like scent. It's made from clove oil's main compound, eugenol, rearranged and then capped with an acetic-acid-derived group.
