How we scored it
Pentacyclic triterpene acid extracted/purified from Centella asiatica; natural plant fragment = 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
Purified from extracts of the Asiatic pennywort plant (Centella asiatica) by extraction and purification. Not manufactured from petrochemical starting materials.
In plain English
A skin-conditioning compound purified from the Centella asiatica (gotu kola) plant, related to asiaticoside. It is isolated directly from the plant rather than synthesised.
