How we scored it
Peptide of Arg, Asn, Gly, Ile and Met only, all proteinogenic (Met counted natural); no caps listed: 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
Made by solid-phase peptide synthesis from amino acids produced by fermentation or protein hydrolysis. Sequence and terminal groups are not given, and no alternative route is known.
In plain English
A short laboratory-made chain of seven amino acids used as a skin-conditioning ingredient. Its building blocks are ordinary amino acids produced by fermentation.
CosIng definition: Heptapeptide-7 is a synthetic peptide consisting of arginine, asparagine, glycine, isoleucine, and methionine
