How we scored it
9-residue peptide (arginine, glycine, leucine, lysine, phenylalanine, proline, tyrosine); amino acids natural = 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
Synthesized from arginine, glycine, leucine, lysine, phenylalanine, proline and tyrosine, amino acids from fermentation or protein hydrolysis. No petrochemical mass remains in the assembled peptide.
In plain English
A small chain of nine amino acids assembled in a lab from natural amino-acid building blocks. Used in skin care to help control oiliness and support the skin barrier.
CosIng definition: Nonapeptide-11 is the synthetic peptide consisting of arginine, glycine, leucine, lysine, phenylalanine, proline and tyrosine
