How we scored it
Botanical extract of defatted seed (n = 1): proteins, sugars, glucosinolates and polyphenols all plant-derived; no synthetic fragment. 1.0 / 1.0 = 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 solvent extraction of woad seed after the oil has been pressed or removed, with the solvent not part of the ingredient. No commercially significant synthetic route exists.
In plain English
An extract of woad (Isatis tinctoria) seeds from which the oil has first been removed, used to condition skin. It holds the seed's remaining natural plant compounds, such as proteins, sugars and polyphenols, drawn out with a solvent.
CosIng definition: Defatted Isatis Tinctoria Seed Extract is the extract of the dried, defatted seeds of Isatis tinctoria, Brassicaceae.
