How we scored it
Copper ion (mineral, natural origin) plus a tripeptide of amino acids (fermentation or protein hydrolysate); coupling reagents and protecting groups leave no mass; all mass natural, 1.0 / 1.0 = 1.00. Sequence not verified.
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
Amino acids from fermentation or hydrolysed protein are coupled into the tripeptide, which is then complexed with a copper salt. Reagents and protecting groups leave no mass in the final complex.
In plain English
A copper complex of a short peptide, used in skin-care products as a skin-conditioning ingredient. The peptide is assembled in the lab from amino acids and then bound to copper. The building blocks are amino acids from fermentation or protein sources plus a copper salt.
CosIng definition: Copper Tripeptide-34 is the complex formed by copper with Tripeptide-34.
