How we scored it
Assembled from 8 natural amino acids (Arg, Asp, Cys, Gly, His, Ile, Lys, Trp); coupling reagents leave no mass. 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
Solid-phase synthesised from individual amino acids, each derived from fermentation or protein hydrolysis. Coupling reagents and protecting groups leave no atoms in the final peptide.
In plain English
A lab-made chain of natural amino acids used to condition skin. Though assembled synthetically, every building block is a natural amino acid, as with other cosmetic peptides.
CosIng definition: Decapeptide-13 is a synthetic peptide consisting of arginine, aspartic acid cysteine, glycine, histidine, isoleucine, lysine and tryptophan
