How we scored it

Na2SiF6 inorganic mineral salt; Na, Si and F are all mineral-origin, extending this site's counter-ion convention to fluorosilicate.
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 from mineral fluorosilicic acid (a byproduct of phosphate rock and silica processing) neutralized with sodium. It is an inorganic mineral salt throughout.

In plain English

An inorganic mineral salt of sodium, silicon and fluorine used for its astringent/mineral properties. It is produced from mineral processing rather than plant or animal sources.
