How we scored it

Glycerol (natural) triesterified with three oleic acid units (natural, vegetable oil); condensation water not counted → 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 vegetable glycerin with oleic acid, the main fatty acid in olive oil. No petrochemical route is used commercially.

In plain English

The main component of olive oil: a skin-conditioning and thickening ingredient made from glycerin and three units of oleic acid, a fatty acid abundant in olive and other vegetable oils.
