How we scored it
12-residue peptide of Ala, Arg, His, Gly, Lys, Phe, Tyr; all atoms are amino-acid atoms and no cap is stated, so natural mass equals total 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
Built by solid-phase peptide synthesis from amino acids obtained by fermentation or from protein hydrolysates. No petrochemical building block is part of the structure described by CosIng.
In plain English
A synthetic peptide, a chain of 12 amino acids, listed with an antimicrobial function. It is assembled in a laboratory by linking amino acids, which are obtained by fermentation or from plant and animal proteins.
CosIng definition: Oligopeptide-8 is a synthetic 12 amino acid peptide consisting of alanine, arginine, histidine, glycine, lysine, phenylalanine and tyrosine
