How we scored it
Disodium carbonate mineral salt; carbonate and sodium are natural origin regardless of mining vs Solvay synthesis. 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
Sodium Carbonate is obtained either by mining natural trona/soda-ash deposits or via the Solvay process from salt and limestone. Both routes yield the same mineral salt.
In plain English
A mineral salt, also called soda ash, either mined or made from salt and limestone. Used to adjust pH and add bulk to powder formulas.
