Is Ethylhexyl Pelargonate natural?

Mostly. Pelargonic acid is taken as oleochemical (cleavage of oleic acid), while 2-ethylhexanol is a petrochemical oxo alcohol made from propylene.

How we scored it

C17H34O2, 270.5 Da: nonanoyl C9H17O 141.2 natural (oleic-acid cleavage); 2-ethylhexoxy C8H17O 129.2 petrochemical (oxo alcohol). 141.2 / 270.5 = 0.52.
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

Pelargonic (nonanoic) acid from ozonolysis of vegetable oleic acid is esterified with petrochemical 2-ethylhexanol. Some pelargonic acid is made by oxo chemistry from octene, which would give 0.00; supplier note.

In plain English

A light, fast-spreading emollient ester that gives skin a smooth, non-oily feel and helps dissolve other oils. It is made by joining pelargonic acid, normally from vegetable oil, to 2-ethylhexanol, which comes from petrochemicals.
