How we scored it

Behenic acid acyl C22H43O 323.6 Da (oleochemical, natural) + tridecyl-oxy C13H27O 199.4 Da (petrochemical oxo alcohol); total C35H70O2 522.9 Da → 0.62.
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.
