How we scored it
35 natural amino acids joined by peptide bonds; synthesis reagents leave no mass in the final product — 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
Chemically synthesized from the listed amino acids (fermentation-derived) via standard peptide-coupling chemistry. No alternative route is significant.
In plain English
A synthetic chain of 35 amino acids formulated to help protect skin, used in protective and anti-aging skincare.
CosIng definition: Oligopeptide-17 is a synthetic 35 amino acid peptide consisting of alanine, arginine, asparagine, aspartic acid, glutamine, glutamic acid, glycine, isoleucine, leucine, lysine, threonine and proline
