How we scored it
17-residue peptide of Ala, Arg, Ile, Lys, Phe and Val only; no acyl cap named, no formula supplied. All atoms from amino acids: 1.00.
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
Amino acids from sugar fermentation or protein hydrolysis are joined by solid-phase peptide synthesis. No alternative route changes the value.
In plain English
A short chain of 17 amino acids (alanine, arginine, isoleucine, lysine, phenylalanine and valine) used as an antimicrobial ingredient. The amino acids come from fermentation or plant protein and are linked together in a factory.
CosIng definition: Oligopeptide-9 is a synthetic 17 amino acid peptide consisting of alanine, arginine, isoleucine, lysine, phenylalanine and valine
