How we scored it
12-amino-acid peptide (Ala, Asn, Gln, Ile, Leu, Lys, Pro only); amino acids are fermentation-derived, coupling chemistry 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 fermentation/hydrolysate amino acids. No alternative route changes this.
In plain English
A lab-made chain of 12 amino acids that helps protect skin. Its building blocks are amino acids from fermentation, so it is fully natural-origin by mass.
CosIng definition: Oligopeptide-13 is a synthetic 12 amino acid peptide consisting of alanine, asparagine, glutamine, isoleucine, leucine, lysine and proline
