How we scored it
12-residue peptide of proteinogenic amino acids (Asn, Asp, Ile, Leu, Met, Phe, Ser, Thr); no acetyl or lipid cap is named; peptides = 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
Dominant route: solid-phase or solution peptide synthesis from fermentation-derived L-amino acids; protecting groups and coupling agents leave no mass. No alternative route is commercially significant.
In plain English
A short peptide, a chain of twelve amino acids, used to condition skin. It is built from natural amino acids (asparagine, aspartic acid, isoleucine, leucine, methionine, phenylalanine, serine and threonine) that are made by fermentation or protein hydrolysis.
CosIng definition: Oligopeptide-55 is a synthetic peptide composed of 12 amino acids consisting of asparagine, aspartic acid, isoleucine, leucine, methionine, phenylalanine, serine, and threonine
