How we scored it
Whole molecule class is expressed vegetable oil (triglycerides); no petrochemical fragment present; natural botanical oil → 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
Expressed by cold-pressing the kernels of hazelnut (Corylus avellana) seeds. No alternative synthetic route exists; it is always a mechanically pressed natural oil.
In plain English
A light oil pressed from hazelnuts, used to soften and condition skin and hair. It comes straight from the nut kernel with no chemical modification, so it is entirely plant-derived.
CosIng definition: Corylus Avellana Seed Oil is the oil expressed from the nuts of the Hazelnut, Corylus avellana L., Betulaceae
