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

Made by neutralizing castor-oil-derived ricinoleic acid with a zinc mineral source. Both the fatty acid and metal ion are natural origin.
