How we scored it

Cedrol (C15H25O-, 221Da, natural, cedarwood-isolated) + acetyl cap (C2H3O, 43Da, petrochemical acetic anhydride) = 222/264 approx 0.84.
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

Cedrol is obtained by fractionating cedarwood essential oil, then acetylated with acetic anhydride. The acetyl group is the only petrochemical mass in the molecule.
