How we scored it
Peel extract: all counted mass is Citrus depressa peel metabolites (n=1, e.g. flavonoids such as nobiletin and tangeretin); solvents ignored. 100% / 100% = 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
Dominant route is solvent extraction of shikuwasa peel, grown mainly in Okinawa and Taiwan. No commercially significant non-plant route exists.
In plain English
