How we scored it
Essential oil of plant-biosynthesised terpenoids (1,8-cineole, camphor, alpha-pinene, borneol), all n=1, so 1.0 (b).
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
Rosemary leaves and stems, grown in Spain, Tunisia, Morocco and elsewhere, are steam-distilled. Synthetic camphor or cineole can be blended into adulterated oils but are not part of the INCI-defined distillate.

Rosemary essential oil, steam-distilled from the leaves and stems of the rosemary shrub. It is listed for antioxidant and skin-conditioning roles and has a herbal scent. Its main components, such as 1,8-cineole, camphor and alpha-pinene, are made by the plant.
