How we scored it
Extract of cultured glasswort callus cells: all mass is plant-cell compounds built from the sugar-based culture medium. Medium additives leave no mass. Natural 1.0 / total 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
Glasswort callus cells are grown in culture on a nutrient medium, then extracted with water or an alcohol/glycol solvent. No alternative route exists; an extract of field-harvested glasswort would score the same.
In plain English
An extract made from cultured cells (callus) of glasswort, a salt-marsh plant, grown in a laboratory nutrient medium. It is used as an emollient (skin softener) and hair conditioner, and consists of the plant cells' own natural compounds.
