How we scored it
Sesquiterpene isolated by fractional distillation of pine turpentine oil; no petrochemical route is commercially used.
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
Recovered by fractional distillation of turpentine oil from pine oleoresin, where it is a major natural component. No synthetic petrochemical route is commercially significant.
In plain English
A woody-smelling compound distilled directly from pine tree resin (turpentine), used in perfumery and skin conditioning. It comes entirely from pine trees.
