How we scored it
Whole botanical extract = 1.0 by this site's convention; the PubChem formula/IUPAC (linoleic acid, C18H32O2) reflects a single marker fatty acid, not the extract itself, and is disregarded per the CosIng description.
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
Made by extracting grape skins, typically a byproduct of winemaking. No alternative synthetic route exists for a botanical extract.
In plain English
An antioxidant extract made from the skins of grapes, often left over from winemaking. Used in skincare to help protect the formula and skin from environmental stress.
CosIng definition: Vitis Vinifera Skin Extract is an extract of the skin of the Grape, Vitis Vinifera L., Vitaceae
