How we scored it
Peptide bond assembly from 7 amino acids (Arg,Cys,Gln,Glu,His,Thr,Val); only condensation water lost, all mass amino-acid derived → 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
Decapeptide-18 is made by linking the seven named amino acids, commercial fermentation or protein-hydrolysate products, via solid-phase peptide synthesis. No petrochemical route exists for this peptide.
In plain English
A lab-made chain of natural amino acids used to condition and smooth skin. The building-block amino acids come from fermentation or protein processing, then are joined together synthetically.
CosIng definition: Decapeptide-18 is a synthetic peptide consisting of arginine, cysteine, glutamine, glutamic acid, histidine, threonine and valine
