How we scored it
Seed extract: all counted mass is Citrus junos seed metabolites (n=1, e.g. limonoids and flavonoids); 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 yuzu seeds, grown mainly in Japan and Korea. No commercially significant non-plant route exists.
