Is Glycol Palmitate natural?

Mostly. Palmitic acid from vegetable oil esterified with petrochemical ethylene glycol; only the fatty-acid portion counts as natural.

How we scored it

Palmitoyl (natural, oleochemical) C16H31O 239.4 Da; ethylene glycol fragment (petrochemical, ethylene oxide route) 61.1 Da → 239.4/300.5 = 0.80.
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

Made by esterifying palmitic acid, a fatty acid from palm or other vegetable oils, with ethylene glycol derived from petrochemical ethylene oxide. No significant bio-based ethylene glycol route is used commercially.

In plain English

A wax-like ester made from palmitic acid, a fatty acid from vegetable oils, combined with ethylene glycol. Used to thicken and add pearly opacity to lotions and shampoos, and to help emulsify oil and water.
