How we scored it
Leaf extract: all mass is plant-derived compounds; extraction solvent leaves 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
Leaves of the sal tree are extracted with water or an alcohol/glycol solvent and concentrated. No synthetic route exists, and any carrier solvent is declared separately on the label.
In plain English
An extract of the leaves of the sal tree, a large hardwood of South Asia, used as an astringent that gives skin a tightening feel. It is made by extracting the leaves with a solvent.
