How we scored it
Extract of Artemisia annua callus (plant cell culture) grown on a typically sucrose-based medium: all biomass carbon is natural-origin sugar. 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
Callus (undifferentiated plant cells) of Artemisia annua is grown in culture on a nutrient medium, typically sucrose and mineral salts, and then extracted. No commercially significant alternative route; extraction of the field-grown plant is a different ingredient.
In plain English
An extract of Artemisia annua (sweet wormwood) cells grown in laboratory culture rather than harvested from the field. It is listed for use as an antimicrobial, antioxidant, hair-conditioning, skin-conditioning and skin-protecting ingredient.
CosIng definition: Artemisia Annua Callus Extract is the extract of the callus of Artemisia annua grown in culture, Compositae
