How we scored it
Cultured plant-cell material built from sucrose and mineral nutrients (n=1); growth regulators and medium additives leave no mass. 1.00 / 1.00 = 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
Larix decidua leaf cells are grown in laboratory or bioreactor culture on a sugar and mineral medium, then harvested and extracted. No synthetic route exists; hormones and other medium additives leave no mass in the extract.
In plain English
An antioxidant and skin-protecting ingredient made from European larch (Larix decidua) leaf cells grown in laboratory culture rather than cut from trees, then extracted. It is a mixture of cell contents, and its makeup depends on the culture and supplier.
CosIng definition: Larix Decidua Leaf Cell Extract is the extract of a culture of the leaf cells of Larix decidua, Pinaceae
