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 esterifying alpha-terpineol, typically produced from turpentine (pine) oil, with petrochemical propionic acid. A minority of terpineol supply is made from petrochemical myrcene.
