How we scored it
Plant extract: all constituents derive from plant biomass (n=1); extraction solvent leaves 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
Harvested Lepidium apetalum seeds are extracted with water, ethanol or glycerin-type solvents, then filtered. No synthetic route exists; a carrier such as propylene glycol is a separate INCI line and is not scored here.
In plain English
An extract of the seeds of Lepidium apetalum, a mustard-family plant used in East Asian herbal traditions. CosIng lists it with skin-lightening ('bleaching') and skin-conditioning functions. It is a mixture of plant compounds, and its makeup depends on the solvent.
CosIng definition: Lepidium Apetalum Seed Extract is an extract of the seeds of Lepidium apetalum, Brassicaceae
