How we scored it
Plant callus cells grown on a sugar and mineral medium; every atom in the biomass is plant-derived (n = 1). Hormones and solvents leave no 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 plant cell culture: Brassica rapa callus is grown on a sucrose-based nutrient medium in flasks or bioreactors, then harvested and extracted. No commercially significant alternative route exists; supplier carriers are declared separately and not counted.
In plain English
An extract of turnip (Brassica rapa) cells grown in a laboratory nutrient culture instead of in a field, then harvested and extracted. It is listed as an antimicrobial, antioxidant, humectant (water-binding) and hair-conditioning ingredient. It is a plant-cell extract, not a synthetic compound.
CosIng definition: Brassica Rapa (Turnip) Callus Extract is the extract of the callus of Brassica rapa grown in culture, Brassicaceae.
