How we scored it

Mg 24.305 Da, metallic element from magnesium minerals: 24.305 / 24.305 = 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 silicothermic (Pidgeon) reduction of dolomite, mainly in China, or electrolysis of magnesium chloride from brines. No petrochemical route exists.

In plain English

Magnesium metal, usually a fine powder, listed in cosmetics for abrasive, antioxidant, reducing and skin-conditioning roles. It is refined from dolomite or from magnesium salts in brines and seawater.

CosIng definition: Magnesium is a metallic element.
