How we scored it
Caffeic acid + hydroxytyrosol + glucose + rhamnose joined by glycosidic/ester bonds; all four building blocks plant-derived, extraction adds no petrochemical mass.
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
Extracted from plant sources such as olive leaves, Buddleja or Verbascum species using aqueous or hydro-alcoholic solvents. No commercial synthetic route exists.
In plain English
A natural antioxidant plant compound found in olive leaves and many other plants, used to protect and brighten skin. Obtained by extraction from plant material.
