How we scored it
C18 unsaturated fatty acid, oleochemical origin within the C8-C22 range = 1.0.
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
