How we scored it
Vegetable oil: triglycerides of seed-derived fatty acids and glycerol, all n=1, so 1.0. No synthetic fragments.
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
Seeds of Pistacia lentiscus grown around the Mediterranean are pressed to expel the fixed oil. No synthetic route exists.
In plain English
