How we scored it

Commercial route: catalytic hydrogenation of coumarin made from phenol-derived salicylaldehyde (Perkin synthesis) — all carbons petrochemical → 0.0.
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

Produced by hydrogenating coumarin, itself synthesised from phenol-derived salicylaldehyde and acetic anhydride. Trace natural occurrence in some plants is not a commercial extraction source.

In plain English

A sweet, tonka-bean-like fragrance ingredient. Almost always made synthetically from petrochemical starting materials rather than extracted from plants, despite occurring naturally in trace amounts.
