How we scored it

Oleic acid C18H34O2 (282.5) minus OH = 265.5 natural; isodecanol C10H22O (158.3) minus H = 157.3 petrochemical oxo-alcohol; 265.5/422.7=0.63.
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 oleic acid, from vegetable oils, with isodecyl alcohol, a branched synthetic alcohol from the petrochemical oxo process. No natural route to isodecyl alcohol is commercially used.

In plain English

An emollient ester of oleic acid, from natural fats and oils, and a synthetic branched alcohol, used to soften and smooth skin in lotions.
