How we scored it
Palmitoyl C16H31O 239 + Lys-Thr residue 246 = 485 Da (C26H51N3O5); all fragments natural, so 485/485 = 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
Dominant route couples fermentation-derived lysine and threonine by peptide synthesis and acylates with palmitic acid from palm or coconut oil. Protecting groups and coupling agents leave no mass in the product.
In plain English
A fatty-acid-linked peptide: palmitic acid joined to two amino acids, lysine and threonine. It is used as a skin-conditioning ingredient. The fatty acid comes from palm or coconut oil and the amino acids from fermentation.
CosIng definition: Palmitoyl Dipeptide-7 is the reaction product of palmitic acid and Dipeptide-7
Structure
(2S,3R)-2-[[(2S)-6-amino-2-(hexadecanoylamino)hexanoyl]amino]-3-hydroxybutanoic acid
