How we scored it

Zn(C6H5O4S)2: Zn + 2x SO3 = 226Da (natural, mineral) + 2x phenolic ring C6H5O = 186Da (petrochemical) = 412Da total. 226/412 = 0.55.
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 sulfonating petrochemical phenol, then neutralizing with zinc oxide or zinc carbonate (mineral-derived). The phenol ring itself has no natural commercial route.

In plain English

An antimicrobial, astringent and deodorant ingredient combining zinc with a sulfonated phenol compound. The zinc and sulfonate portions are mineral-derived; the phenol ring is a synthetic petrochemical building block.
