How we scored it
K+ (mineral ion, natural) + aspartate C4H6NO4 (fermentation amino acid) = 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
Made by reacting a potassium base with fermentation-derived L-aspartic acid. No significant alternative route exists.
In plain English
A potassium salt of the amino acid aspartic acid, used for skin conditioning. The potassium is mineral and the aspartic acid comes from fermentation.
