Is Propylene Glycol Dioleate natural?

Mostly. The propylene glycol backbone is petrochemical; both oleic-acid ester groups are natural, oleochemical-derived.

How we scored it

PG backbone (petrochemical) 74.08 Da + 2x oleoyl (natural C18 fatty acid) 530.92 Da → 530.92/605.0 = 0.88.
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 petrochemical propylene glycol with oleic acid from vegetable oils such as sunflower or olive. No natural route exists for the propylene glycol portion.

In plain English

An emollient that softens skin, made by combining propylene glycol (a synthetic glycol) with oleic acid, a fatty acid typically from vegetable oils.
