How we scored it

Aldol condensation of benzaldehyde with octanal; both are predominantly petrochemical commercial feedstocks and the molecule is not isolated from any essential oil = 0.0
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.

How it’s made

Aldol condensation (base). Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Manufactured by aldol condensation of benzaldehyde with octanal, both typically petrochemical-derived (oxo-synthesis). It does not occur in extractable amounts in any commercial essential oil.
