How we scored it
Recombinant/synthesised peptide of 10 natural amino acids (Arg, Gly, Leu, Lys, Phe, Pro, Tyr); peptides built from amino acids are natural-origin regardless of synthesis route.
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
A biotech-produced peptide identical to a fragment of human endorphin, assembled from natural amino acids (fermentation/protein-hydrolysate sourced) via recombinant or synthetic coupling. Single route.
In plain English
A lab-made peptide designed to match a natural skin-conditioning protein fragment. Built from the same natural amino acids found in the body.
CosIng definition: sh-Decapeptide-9 is a recombinant human peptide produced synthetically to be identical to the protein, Endorphin. It contains 10 amino acids consisting of arginine, glycine, leucine, lysine, phenylalanine, proline and tyrosine
