How we scored it
Leaf extract: terpenoids, phenolics, flavonoids and other plant constituents all n = 1; extraction solvent leaves no mass. Natural mass 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 water or solvent extraction of turmeric leaves. No alternative route is in commercial use.
