How we scored it
Sesquiterpene isolated from citrus peel oil (or bio-fermentation); no petrochemical synthesis route is commercially significant.
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
Predominantly recovered by fractional distillation of orange peel oil, a low-cost byproduct of citrus juice production; increasingly also produced by fermentation. No petrochemical synthesis is commercially used, as natural supply is abundant and cheap.
In plain English
A citrusy-smelling compound recovered from orange peel oil left over from juice-making, used in fragrance and as the source material for grapefruit-scented nootkatone. It comes entirely from oranges.
