How we scored it
Extract of plant cell biomass, all plant-derived (n = 1). Culture-medium sugars and minerals are natural; growth regulators and solvents leave no mass. 1.0 / 1.0 = 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
Cells from Centella asiatica leaf tissue are cultured in sterile bioreactors on a nutrient medium, harvested and extracted with a solvent. Supplier media differ, but any synthetic growth regulators are trace and ignored.
In plain English
An extract made from Centella asiatica (gotu kola) leaf cells grown in tanks of nutrient solution rather than harvested from the plant. The EU ingredient database lists it as an antioxidant and skin-protecting ingredient. The cells are extracted with a solvent.
