How we scored it
Extract of olive leaf cells grown in culture: cell metabolites, lipids and sugars are plant-cell-derived (n=1); culture medium and solvent leave no mass. The CAS given is olive oil; the description governs. Total 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
Dominant route is plant cell culture: olive leaf cells are grown in a bioreactor on a sugar-and-mineral medium, then extracted. No alternative route is commercially significant.
