How we scored it
12-amino-acid peptide (Ala, Cys, Leu, Lys, Pro, Ser, Tyr only); amino-acid building blocks, no caps. 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.
In plain English
A lab-made peptide of amino acids used to condition skin. Since amino acids come from fermentation, it counts as fully natural-origin.
CosIng definition: Oligopeptide-19 is a synthetic 12 amino acid peptide consisting of alanine, cysteine, leucine, lysine, proline, serine and tyrosine
