How we scored it

Ester of decyl alcohol (C10, natural) + oleic acid (C18, natural); both oleochemical fragments → 1.00.
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.

How it’s made

Fischer esterification of oleic acid with decyl alcohol. Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Made by esterifying natural decyl alcohol, coconut-derived, with natural oleic acid from vegetable oils such as olive or sunflower. No petrochemical variant is used commercially.

In plain English

A lightweight, silky emollient that helps products glide onto skin. Both its building blocks come from natural coconut and vegetable oil fatty acids.
