How we scored it
12 natural amino acids (incl. cystine) joined by peptide bonds; synthesis reagents leave 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
Chemically synthesized from the listed amino acids (fermentation-derived) via standard peptide-coupling chemistry. No alternative route is significant.
In plain English
A lab-made short peptide formulated to condition and support the skin, used in moisturizing and anti-aging products.
CosIng definition: Oligopeptide-18 is a synthetic 12 amino acid peptide consisting of alanine, cystine, leucine, lysine, proline, serine and tyrosine
