How we scored it
Palmitoyl cap (oleochemical), seven amino acids (fermentation or hydrolysate) and Cu ion (mineral) are all natural origin; no acetyl cap. 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
Palmitic acid from palm or coconut oil is coupled to a heptapeptide assembled from fermentation-derived amino acids, then complexed with copper from mineral sources. Protecting groups and coupling reagents leave no mass, and the sequence is assumed to use natural amino acids only.
In plain English
A copper-peptide complex: a seven-amino-acid peptide carrying a palmitic acid tail and bound to copper, used for skin conditioning. The fatty acid comes from palm or coconut oil, the amino acids from fermentation, and the copper from mineral sources.
CosIng definition: Copper Palmitoyl Heptapeptide-14 is the copper salt of the product formed by the reaction of palmitic acid and Heptapeptide-14.
