How we scored it

Na2B4O7 decahydrate; sodium and borate are both natural mineral 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 refined from natural borax mineral deposits or crystallised from natural brine sources. No petrochemical route is used.
