How we scored it

C13H18O aryl aldehyde: benzene ring, tert-butyl and propanal chain all petrochemical; no natural or mineral atoms; 0/190 = 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.

Where it comes from

Dominant route: 4-tert-butylbenzaldehyde (from toluene and isobutylene) undergoes crossed aldol condensation with acetaldehyde and selective hydrogenation. No natural-origin route is commercial.
