How we scored it
CosIng defines this as a grape callus-cell-culture extract (botanical extract, =1.0); attached PubChem formula (linoleic acid, C18H32O2) does not represent a cell-culture extract and is disregarded per description authority.
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
Produced by growing grape callus (undifferentiated plant stem cells) in culture and extracting the resulting biomass. No alternative synthetic route exists.
In plain English
