Route-dependent · ISO 16128

Is Rhodinyl Formate natural?

It depends. Citronellol (rhodinol) comes from rose/citronella oil extraction or synthetic hydrogenation routes; formic acid used is typically 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
naturalcitronella/rose oil citronellol + petrochemical formic acid0.84~35%
syntheticsynthetic citronellol + petrochemical formic acid0.00~65%, 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 citronellol+formic acid. Natural-citronellol route: 155/184=0.84. Synthetic-citronellol + petrochemical formic acid: 0.0. Headline shows the best route (0.84), 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

Citronellol is sourced either by extraction from citronella or rose oil, or by synthetic hydrogenation of petrochemically- or turpentine-derived intermediates; the synthetic route is the larger-volume commodity supply.

In plain English

A rose-like fragrance ingredient made from citronellol joined with formic acid. It can come from natural rose or citronella oil, but most supply is made synthetically.
