How we scored it
Peptide of Ala, Asn, Cys, His, Leu, Thr and Trp only, all proteinogenic (Cys 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 ten amino acids used as a skin-conditioning ingredient. Its building blocks are ordinary amino acids produced by fermentation or protein breakdown.
CosIng definition: Decapeptide-20 is the synthetic peptide consisting of alanine, asparagine, cysteine, histidine, leucine, threonine and tryptophan
