How we scored it
Water = 1.0 per this site's method; dissolved sea minerals also count as 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
Collected directly from the sea or inland salt-water bodies, then filtered for cosmetic use. No synthetic alternative is used; this is a natural raw material by definition.
In plain English
Simply sea water, drawn from the ocean or salt lakes. Provides moisture and dissolved minerals, and acts as a solvent base for other ingredients in a formula.
CosIng definition: Sea Water is water obtained from the sea or from inland bodies of salt water
