How we scored it
C10H18O 154.3; terpene skeleton from tea tree oil or pine turpentine terpenes (b), no petrochemical C2-C5 build-up. 154.3 / 154.3 = 1.0.
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
Fractionated from tea tree (Melaleuca alternifolia) oil, where it is the main component, or synthesised from turpentine-derived terpenes. No petrochemical C5-block route is in commercial use.
