How we scored it
Dipeptide of cysteine and lysine; amino acids are natural-origin and coupling reagents leave no mass, so 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
Chemically synthesised by coupling the amino acids cysteine and lysine, both obtainable from fermentation or protein hydrolysis. No petrochemical alternative route.
In plain English
A small peptide made from two natural amino acids, cysteine and lysine, used to condition skin.
CosIng definition: Dipeptide-11 is the synthetic peptide consisting of cysteine and lysine
