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 Lycium ruthenicum plant material is 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 whole Lycium ruthenicum plant (black wolfberry), listed for hair and skin conditioning. It is a mixture of plant compounds, and its makeup depends on the plant part, solvent and supplier.
CosIng definition: Lycium Ruthenicum Extract is the extract of the whole plant, Lycium ruthenicum
