How we scored it
Solvent extract of pyrethrum flowers: pyrethrins and other metabolites are plant-made; extraction solvent and carrier leave no mass. Natural 100% / total 100% = 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 of pyrethrum flower heads. No synthetic route exists for the extract itself; synthetic pyrethroids are separate substances.
