100% natural origin · ISO 16128

Is Manganese Dioxide natural?

Yes. Manganese and oxygen come from the mineral pyrolusite or from manganese salts, which count as natural-origin minerals under ISO 16128.

How we scored it

Mn 54.9 + 2 O 32.0 = 86.9 Da; all mineral, natural origin under ISO 16128: 86.9/86.9 = 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 source is mined pyrolusite ore, crushed and purified. Synthetic grades made from manganese sulfate by electrolysis or oxidation are also mineral-derived and give the same value.

In plain English

A dark mineral powder listed in cosmetics as an antioxidant. It occurs naturally as the ore pyrolusite and is also produced industrially from manganese salts.
