How we scored it
Botanical extract from cultured tea-plant cells; the listed formula (C22H18O11) reflects one polyphenol marker compound, not the whole extract, which is scored 1.0 as a plant-derived extract.
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
This extract is produced by growing callus cells cultured from the tea plant, Camellia sinensis, then extracting the culture. The attached formula appears to describe a single marker polyphenol rather than the full extract.
In plain English
A skin-conditioning extract grown from lab-cultured tea plant cells rather than harvested tea leaves. It still originates from the tea plant, Camellia sinensis.
CosIng definition: Camellia Sinensis Callus Culture Extract is the extract of a culture of the callus cells of the Tea, Camellia sinensis, Theaceae
