How we scored it
Suspension of cultured peppermint meristem cells: cell mass is plant material (n=1); culture medium and growth additives leave no mass in the substance. 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 route is plant-cell biotechnology: Mentha piperita meristem cells grown in sterile liquid culture and harvested. The suspending liquid is typically aqueous or glycerin-based but is not specified, hence medium confidence.
In plain English
A suspension of plant cells grown in a laboratory from the growing tip (meristem) of peppermint, instead of harvesting the whole plant. It is listed as a skin-conditioning ingredient. The cells are plant-derived.
CosIng definition: Mentha Piperita (Peppermint) Meristem Cell Culture is a suspension of the cultured meristem cells of Mentha piperita.
