Is Isotridecyl Isononanoate natural?

No. Both the branched alcohol and branched acid are oxo-process petrochemical products, not oleochemicals.

How we scored it

Isotridecanol (oxo-process branched alcohol) esterified with isononanoic acid (oxo-process branched acid); both petrochemical = 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

Manufactured by esterifying isotridecanol with isononanoic acid, both branched C9-C13 building blocks made industrially from propylene/butene via oxo (hydroformylation) chemistry. No natural-origin route exists for either fragment.

In plain English

A lightweight, silky oil made by combining two branched synthetic building blocks (isotridecanol and isononanoic acid), both derived from petrochemical feedstocks. Used as an emollient for a smooth, non-greasy skin feel.
