How we scored it
Stearic acid + KOH neutralisation; fatty acid natural, potassium counterion natural. 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
The potassium salt of stearic acid, a fatty acid derived from vegetable oils or animal tallow. The neutralising base leaves only the natural potassium ion in the product.
