How we scored it
Essential oil (petitgrain) of bitter orange leaves and twigs: linalyl acetate, linalool, terpineol and other terpenoids, all plant-made (n = 1). Natural mass / total mass = 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 bitter orange leaves and twigs, steam-distilled, with Paraguay the largest supplier and smaller output from the Mediterranean. No synthetic route exists for the oil.
