How we scored it
Steam-distilled essential oil: anethole, fenchone, limonene and other volatiles are all isolated from the plant; terpenes natural under b. Natural mass fraction 1/1 = 1.00.
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
Dominant feedstock is fennel (mostly seed) steam distilled to a volatile oil. No commercially significant synthetic route exists for the oil itself; constituents such as anethole are sold separately under their own INCI names.
In plain English
A fragrance ingredient with a sweet, aniseed-like smell. It is the volatile essential oil steam distilled from the fennel plant.
CosIng definition: Foeniculum Vulgare Oil is the volatile oil obtained from the whole plant, Foeniculum vulgare.
