How we scored it
Myristic acid (C14 oleochemical) amide-bonded to Hexapeptide-16 (fermentation amino acids); both fragments natural → 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
Coconut or palm-kernel-derived myristic acid is coupled to a synthetically assembled hexapeptide made from fermentation amino acids. No petrochemical route is used.
In plain English
A skin-conditioning ingredient pairing a plant-oil fatty acid with a chain of six amino acids. Both components come from natural oils and fermentation, joined together during manufacture.
CosIng definition: Myristoyl Hexapeptide-16 is the product of the reaction of myristic acid and Hexapeptide-16
Structure
