Is Glyceryl Ethylhexanoate Dimethoxycinnamate natural?

Mostly not. Glycerin core is natural; the methoxycinnamoyl groups derive from petrochemical aromatics (anisole/anisaldehyde) and 2-ethylhexanoic acid from propylene oxo chemistry.

How we scored it

Glycerol core C3H5O3 89.1 Da natural; 2 x 4-methoxycinnamoyl C10H9O2 161.2 each and 2-ethylhexanoyl C8H15O 127.2 petrochemical. 89.1 / 538.6 = 0.17.
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

Glycerin from vegetable-oil processing is esterified with two 4-methoxycinnamic acid units (from anisaldehyde condensation) and one 2-ethylhexanoic acid (propylene oxo process). No natural-origin source of the cinnamate or ethylhexanoate is commercially significant.

In plain English

A UV-absorbing ingredient used in sunscreen products to absorb UVB light. It is a glycerin backbone carrying two methoxycinnamate groups and one 2-ethylhexanoate group, built mainly from petrochemical-derived aromatics and 2-ethylhexanoic acid.
