How we scored it
Extract of cultured stock-flower callus: cell mass is plant material (n=1); culture medium and extraction solvent leave no mass in the substance. 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 biotechnology: Matthiola incana callus grown in sterile culture and then extracted with water or glycerin-water. No alternative route exists; the exact carrier is not specified, hence medium confidence.
In plain English
An extract of plant cells grown in a laboratory from tissue of the stock flower (Matthiola incana), rather than from the harvested plant. It is listed for antioxidant, humectant, hair-conditioning and skin-conditioning uses. The material is plant-derived.
CosIng definition: Matthiola Incana Callus Culture Extract is the extract of a culture of the callus of Matthiola incana, Brassicaceae
