How we scored it
Na2O4S is a simple inorganic mineral salt; sodium and sulfate are both natural-origin mineral fragments. 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
Produced either by mining natural mineral deposits (mirabilite/thenardite) or as a by-product salt from mineral-acid neutralisation. Either route is mineral, natural-origin material.
In plain English
A mineral salt used to bulk out and thicken formulas. It's the same type of sulfate salt found naturally in mineral deposits.
Structure
disodium;sulfate
