How we scored it
Palmitic acid C16H32O2 (natural, oleochemical) neutralised with K (natural mineral counter-ion) - whole salt natural, no petrochemical fragment.
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
Made by saponifying vegetable-oil-derived palmitic acid with potassium hydroxide. No petrochemical route is commercially used for this fatty acid salt.
In plain English
