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 from natural clay deposits formed from weathered volcanic ash, then purified by washing and milling. No synthetic route exists.
