How we scored it
Assembled from 7 natural amino acids (Arg, Gly, Leu, Lys, Phe, Pro, Tyr); synthesis leaves 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 amino acids sourced from fermentation or protein hydrolysis. No petrochemical mass is retained in the final peptide.
In plain English
A lab-assembled chain of natural amino acids used to condition skin. All its building blocks are natural amino acids, even though it's made synthetically.
CosIng definition: Decapeptide-17 is a synthetic peptide consisting of arginine, glycine, leucine, lysine, phenylalanine, proline and tyrosine
