How we scored it
Pentacyclic triterpene acid extracted directly from plant material (olive leaves, cloves); all carbon plant-derived. 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
Oleanolic acid is obtained by extracting olive leaf, olive pomace or clove buds, where it occurs naturally. It is used as extracted or after minor purification, with no petrochemical synthesis route.
In plain English
A skin-conditioning compound naturally present in olive leaves, cloves and many other plants, obtained by extracting it from that plant material. The whole molecule is plant-derived.
