How we scored it
Extract of cultured plant tissue (n = 1); medium sucrose and minerals are natural, trace growth regulators leave no meaningful mass. 1.0 / 1.0 = 1.00.
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 biotechnological culture of coneflower callus on a sucrose-based medium, followed by water or glycerin extraction of the cells. No commercially significant synthetic route exists.
In plain English
An extract of plant tissue (callus) grown in a laboratory from narrow-leaved coneflower, Echinacea angustifolia, used to condition skin. The tissue grows on a sugar-based nutrient gel, and the extract holds its natural plant compounds.
CosIng definition: Echinacea Angustifolia Callus Extract is the extract of the callus of Echinacea angustifolia grown in culture.
