How we scored it
Ethanol (assumed fermentation-derived) esterified with oleic acid (natural C18 fatty acid); both fragments natural, 1.0.
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 fermentation ethanol, from corn, sugarcane or grain, with oleic acid from vegetable oils. A minor petrochemical ethanol route exists but is not dominant in cosmetic supply.
In plain English
An emollient and fragrance ester made by combining ethanol, typically fermentation-derived, with oleic acid from natural fats and oils.
