How we scored it
Whole steam-distilled essential oil; no synthetic fragments; distilled botanical oils are 1.0 by rule.
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
Produced by steam distillation of tea tree leaves, mainly from Australian plantations. No alternative synthetic route exists.
In plain English
