Is Tridecyl Ethylhexanoate natural?

No. Tridecyl alcohol is an odd-chain oxo alcohol from petrochemical olefins and 2-ethylhexanoic acid is made from propylene, so no fragment is natural origin.

How we scored it

Tridecyl-O C13H27O is a branched oxo alcohol from butene or propylene oligomers (0); 2-ethylhexanoyl C8H15O from propylene oxo (0); total C21H42O2 326.6; 0/326.6 = 0.00.
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: isotridecanol from propylene or butene oligomers by hydroformylation, esterified with 2-ethylhexanoic acid from propylene-derived butyraldehyde. An odd-chain C13 alcohol has no commercial oleochemical route, so there is no natural alternative.

In plain English

A light emollient ester that softens skin and helps products spread. Both halves are made from petrochemical raw materials: tridecyl alcohol from propylene or butene oligomers, and 2-ethylhexanoic acid from propylene.
