Is Triethoxycaprylylsilane natural?

No. A silane coupling agent used to coat pigments; like the silicones it is scored 0 by convention rather than by mass fraction.

FeedstockSilicon metal from quartz, octene (petrochemical) and ethanol,…

How we scored it

Organosilicon compounds (silicones and silanes) score 0 by this site's convention, whatever their side chains, so the octyl chain and the ethoxy groups are not credited; compare Stearoxytrimethylsilane.
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

Silicon metal from quartz, octene (petrochemical) and ethanol, combined by hydrosilylation and alkoxylation.

In plain English

A binding and surface-treatment ingredient that helps pigments and powders disperse evenly and resist water. It combines a coconut/palm-derived fatty chain with a silicon compound made using ethanol.
