How we scored it
Nonapeptide (9 residues) from alanine, glutamine, glycine, proline, threonine; amino acids natural, coupling 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 synthesised from standard amino acids obtainable via fermentation or protein hydrolysis. No petrochemical route for the final peptide.
In plain English
A lab-made peptide built from natural amino acids, used to condition hair and protect skin.
CosIng definition: Nonapeptide-13 is the synthetic peptide consisting of alanine, glutamine, glycine, proline and threonine.
