How we scored it
Dipeptide identity not given; two amino acids (fermentation or hydrolysate) plus ionic chloride from HCl (mineral); no caps or petrochemical atoms assumed. 1.00.
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
Two fermentation-derived amino acids are coupled by peptide synthesis, with protecting groups and coupling agents leaving no mass, and isolated as the hydrochloride. A residue made solely by chemical synthesis would lower the value.
In plain English
A short chain of two amino acids supplied as its hydrochloride salt and used as a skin-conditioning ingredient in serums and creams. The peptide is assembled from amino acids that are made by fermentation.
CosIng definition: Dipeptide-8 HCl is the hydrochloride salt of Dipeptide-8
