How we scored it
Mixed inorganic salts from evaporated seawater; all mineral-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
Maris Sal is produced by evaporating natural seawater to leave its mineral salts. There is no synthetic alternative; it is always a natural mineral mixture.
In plain English
Sea salt, made of the natural mineral salts found in seawater, used as a skin-conditioning ingredient.
CosIng definition: Naturally occurring substances, inorganic salts derived from sea water
