Is PPG-3 Myristyl Ether Neoheptanoate natural?

Mostly not. Myristyl alcohol is assumed oleochemical coconut or palm kernel origin, while propylene oxide and the synthetic neoheptanoic acid are petrochemical.

How we scored it

Myristyl-O C14H29O 213 Da natural; 3 PO units C9H18O3 174 Da + neoheptanoyl C7H13O 113 Da petrochemical; total 501 Da; 213.4 / 500.8 = 0.43.
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

Myristyl alcohol from hydrogenated coconut or palm kernel fatty acids is propoxylated with three propylene oxide units and esterified with neoheptanoic acid made from olefins and carbon monoxide. Ziegler-derived myristyl alcohol is a possible petrochemical variant, so a supplier note is advised.

In plain English

A light, silky emollient that helps products spread and gives a dry, light skin feel. It joins myristyl alcohol from plant oils with three propylene oxide units and a branched seven-carbon acid, both made from petrochemicals.
