How we scored it
Plant cell-culture extract: compounds made by the cells are n = 1; medium nutrients, growth regulators and solvent are reagents that leave no mass. Natural mass 100% = 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
Dominant route is plant cell suspension culture in a bioreactor, followed by cell lysis and extraction. Extraction of field-grown bilberry leaves would also be natural origin.
In plain English
An extract from bilberry (Vaccinium myrtillus) leaf cells grown in a culture tank rather than harvested from plants, used to condition skin. The cells are grown on a sugar and mineral medium, then broken open and extracted.
CosIng definition: Vaccinium Myrtillus Leaf Cell Extract is the extract of a culture of the leaf cells of Vaccinium myrtillus, Ericaceae.
