How we scored it

Piroctone (fully synthetic branched pyridinone) as its ethanolamine (olamine) salt; both fragments petrochemical, no natural route = 0.0.
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

Piroctone is manufactured entirely by organic synthesis from petrochemical building blocks and neutralised with ethanolamine, itself made from ethylene oxide and ammonia. No natural route exists for either fragment.

In plain English

An anti-dandruff ingredient that helps control flaking, used in its amine-salt form. Made entirely through chemical synthesis from petrochemical starting materials, with no natural source.

CosIng definition: Piroctone Olamine is the amine salt that conforms to the formula:
