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

Manufactured by condensation of petrochemical-derived ketones into the cyclopentenone ring. No commercially significant natural-extraction route exists despite trace natural occurrence in jasmine.

In plain English

A synthetic fragrance ingredient with a fruity, jasmine-like, slightly musky scent. It's manufactured from petroleum-derived chemicals to recreate a note found in trace amounts in real jasmine.
