Is Tridecyl Erucate natural?

Mostly. The C22 fatty acid is natural; tridecyl alcohol is an odd-carbon oxo alcohol made from petrochemical olefins. Same method as Tridecyl Stearate.

How we scored it

Erucic acid acyl C22H41O 321.6 Da (oleochemical, natural) + tridecyl-oxy C13H27O 199.4 Da (petrochemical oxo alcohol); total C35H68O2 520.9 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.

Where it comes from
