How we scored it
Botanical extract (n = 1): flavonoids, tannins, terpenoids and sugars all plant-derived; no synthetic fragment. 1.0 / 1.0 = 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 route is solvent extraction (water, glycerin or ethanol-water) of fleabane flowers; the solvent is not part of the INCI ingredient. No commercially significant synthetic route exists.
In plain English
