Is Magnesium Bromide natural?

Yes. Magnesium and ionic bromide are mineral-origin ions from brines, with no carbon-bound halogen or organic part.

How we scored it

Mg 24.3 Da + 2 Br 159.8 Da (ionic bromide, mineral) = 184.1 Da; all mineral, natural origin = 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

Bromine recovered from brines such as the Dead Sea is combined with magnesium oxide or hydroxide from magnesite or seawater. No organic or petrochemical route is significant.

In plain English

A mineral salt of magnesium and bromide used to adjust the thickness of some products. It is obtained from salt-lake or sea brines.
