Route-dependent · ISO 16128

Is Rhodinyl Acetate natural?

It depends. Rhodinol is a natural geranium or rose fraction but is also made from synthetic citronellol; the acetyl group is petrochemical. Same ruling as Rhodinyl 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 rhodinylrhodinyl of natural origin + acetic acid from petrochemical synthesis0.78Rhodinyl fragment C10H19O 155.3/198.3 = 0.78.
syntheticrhodinyl and acetic 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

Rhodinyl Acetate C12H22O2 198.3 Da: rhodinyl fragment C10H19O 155.3 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 rhodinyl 0.78, 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

Rhodinol (geranium-oil fraction or synthetic citronellol) acetylated with acetic anhydride.

In plain English

A fragrance ester made from a rose or citronella-derived terpene alcohol and a manufactured acid. Gives products a rosy, fruity scent.
