How we scored it
91-amino-acid synthetic peptide from 17 standard amino acid types (incl. hydroxyproline); all residues natural, coupling/host 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
Synthesised (or produced recombinantly) from the 20 standard amino acids plus hydroxyproline, all obtainable via fermentation or protein hydrolysis. No petrochemical route for the final peptide.
In plain English
A large, lab-made peptide built from natural amino acids, used to condition skin. Its size makes the exact production route less certain.
CosIng definition: Oligopeptide-4 is a synthetic 91 amino acid peptide consisting of alanine, arginine, aspartic acid, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tyrosine and valine
