Dolomite has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Mined mineral composed of calcium, magnesium and carbonate, all counted as natural origin. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

Is Dolomite natural? NOI 1.00

How we scored it

CaMg(CO3)2 mineral; calcium, magnesium and carbonate are all natural-origin.

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

Mined and milled from natural dolomite rock deposits. No synthetic manufacturing route is used.

In plain English

A mined mineral, calcium magnesium carbonate, used as a mild abrasive and opacifier in scrubs and powder products.

CosIng definition: Dolomite is a mineral constituted of calcium magnesium carbonate
