100% natural origin · ISO 16128

Is Oligopeptide-7 natural?

Yes. Peptide bonds join amino acids of fermentation or protein-hydrolysate origin; coupling reagents and protecting groups leave no mass in the final peptide.

INCI nameOligopeptide-7
FunctionAntimicrobial
FeedstockBuilt by solid-phase peptide synthesis from alanine, lysine…

How we scored it

23-residue peptide of Ala, Lys and Phe only; 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 alanine, lysine and phenylalanine 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 23 amino acids made only from alanine, lysine and phenylalanine, 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-7 is a synthetic 23 amino acid peptide consisting of alanine, lysine and phenylalanine
