How we scored it

Formula C85H143N29O21 (1907 Da) fits an uncapped peptide of the nine listed amino acids; every atom is amino-acid derived, so natural mass 1907 / total 1907 = 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 amino acids obtained by fermentation or from protein hydrolysates. No petrochemical building block is part of the structure given by the formula.

In plain English

A synthetic peptide, a chain of about 15 amino acids, used as a skin-conditioning ingredient. It is assembled in a laboratory by linking amino acids, which are obtained by fermentation or from plant and animal proteins.

CosIng definition: Oligopeptide-6 is a synthetic peptide consisting of alanine, arginine, asparagine, aspartic acid, isoleucine, leucine, lysine, phenylalanine and threonine
