How we scored it
Palmitic acid (natural C16 fatty acid) amide-bonded to Dipeptide-18 (natural amino acids); the acid-chloride leaving group (Cl) leaves no mass. 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
Palmitic acid (from vegetable/animal fat) is coupled to a peptide of natural amino acids via an acid-chloride reaction; the chloride leaves as HCl. No petrochemical route reported.
In plain English
A peptide ingredient attached to a natural fatty acid tail, used to help control product thickness. Built from natural fat-derived and amino-acid building blocks.
CosIng definition: Palmitoyl Dipeptide-18 is the product obtained by the reaction of palmitoyl chloride and Dipeptide-18
