How we scored it
Cassava leaf extract: every constituent is plant-derived (n=1); extraction solvent leaves no mass in the substance. 1.0 x 100% = 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
Dominant feedstock is the leaf of cassava (Manihot esculenta, synonym M. utilissima) extracted with water or water-alcohol. No alternative route exists; any carrier solvent is declared as its own ingredient.
In plain English
A plant extract made by soaking cassava (tapioca plant) leaves in a solvent and filtering. It is listed as a skin-protecting ingredient. It comes entirely from the cassava leaf.
CosIng definition: Manihot Utilissima Leaf Extract is an extract of the leaves of the Tapioca, Manihot utilissima, Euphorbiaceae
