How we scored it
12-amino-acid peptide (Asp, Leu, Lys only); amino-acid building blocks only, 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 synthetic peptide built from amino acids, used to condition skin. The amino acids are fermentation-derived, so it counts as fully natural-origin.
CosIng definition: Oligopeptide-26 is the synthetic peptide containing 12 amino acids consisting of aspartic acid, leucine, and lysine; Aspartic acid, dodecapeptide with leucine and lysine
