How we scored it
Guava leaf volatile oil: terpenes such as caryophyllene, cineole and pinene are plant-made; no added fragment, natural mass equals total mass, 1.0.
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

In plain English
