How we scored it
12-residue peptide from alanine, arginine, aspartic acid, histidine, leucine, proline, threonine and tryptophan; no caps declared; protecting groups 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
Dominant route: solid-phase peptide synthesis from fermentation-derived protected amino acids. No alternative route is commercially significant.
In plain English
A made-in-the-lab chain of 12 amino acids (alanine, arginine, aspartic acid, histidine, leucine, proline, threonine and tryptophan), used to condition skin. The amino acids come from fermentation or protein hydrolysis.
CosIng definition: Oligopeptide-71 is the synthetic peptide containing 12 amino acids consisting of alanine, arginine, aspartic acid, histidine, leucine, proline, threonine and tryptophan.
