How we scored it
Peptide built from 5 amino acid types (Arg/His/Lys/Phe/Trp); amino acids are fermentation/hydrolysate products, synthesis reagents 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
Synthesised by chemically linking amino acids (arginine, histidine, lysine, phenylalanine, tryptophan) obtained from fermentation or protein hydrolysis. No alternative route noted.
In plain English
A lab-made chain of eight amino acids used to condition skin. Built from the same amino acids found in proteins, though assembled synthetically rather than extracted.
CosIng definition: Octapeptide-5 is the synthetic peptide consisting of arginine, histidine, lysine, phenylalanine and tryptophan
