How we scored it
Inorganic iron hydroxide mineral; iron, oxygen and hydrogen are mineral-origin, analogous to iron oxides named. 72.85/72.85 = 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
Produced from iron mineral/ore sources through mineral processing. No petrochemical alternative exists.
In plain English
A mineral-based ingredient that helps protect a formula from light degradation. It's made from iron ore through mineral processing, not from petroleum.
