How we scored it
Dried, ground plant tissue (n = 1) with no chemical modification; no reagent or solvent mass in the product. 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 harvesting, drying and milling birch leaves to a fine powder with no chemical conversion. No commercially significant alternative route exists.
In plain English
A fine powder made by drying and grinding the leaves of the birch tree (Betula pubescens, historically called Betula alba). It is listed as an exfoliating ingredient, giving a scrubbing action, and is plant material without chemical modification.
