Is Ethylhexyl Isononanoate natural?

No. Both the alcohol and the acid are made via petrochemical oxo-synthesis from propylene/butene streams.

How we scored it

2-Ethylhexanol (oxo-process, petrochemical) esterified with isononanoic acid (oxo-process from diisobutylene, petrochemical). No natural fragment.
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

Ester of 2-ethylhexanol and isononanoic acid, both produced by hydroformylation (oxo process) of petrochemical olefins. No natural-origin route is used commercially for either fragment.

In plain English

A light, fast-absorbing emollient ester made from two synthetic petrochemical building blocks, 2-ethylhexanol and isononanoic acid. It gives lotions and sun-care products a silky, non-greasy feel.
