How we scored it
11-residue peptide of Asp, Cys, Gln, Gly, His, Phe, Ser, Thr, Tyr; no cap listed in CosIng; all residues natural amino acids (cysteine S is amino-acid sulfur); full mass natural, 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
Fermentation-derived amino acids are coupled by solid-phase peptide synthesis into the 11-residue chain. No alternative route is significant.
In plain English
A synthetic chain of eleven amino acids used to condition skin. It is assembled in a lab from amino acids that are normally produced by fermentation or protein hydrolysis.
CosIng definition: Oligopeptide-44 is a synthetic 11 amino acid peptide consisting of aspartic acid, cysteine, glutamine, glycine, histidine, phenylalanine, serine, threonine, and tyrosine
