How we scored it
Copper salt of lysine + proline amino acids; Cu counter-ion natural-origin, whole complex 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
Produced by complexing copper with the amino acids lysine and proline, which are obtained by fermentation or protein hydrolysis. No petrochemical fragment is present in the final complex.
In plain English
A copper complex of two amino acids, lysine and proline, used to condition skin. Both the amino acids and the copper are considered natural-origin.
CosIng definition: Copper Lysinate/Prolinate is the copper salt of a mixture of Proline and Lysine
