How we scored it
Myristic acid (natural C14 fatty acid) amide-bonded to Pentapeptide-17 (amino-acid peptide, natural). 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
Myristoyl Pentapeptide-17 is made by attaching myristic acid, typically from coconut or palm kernel oil, to a synthetic peptide built from natural amino acids. Both building blocks are natural-origin.
In plain English
A peptide ingredient used to condition and support skin, made by joining a coconut-derived fatty acid to a small chain of amino acids. Both components come from natural, fermentation- or plant-based sources.
CosIng definition: Myristoyl Pentapeptide-17 is the product of the reaction of myristic acid and Pentapeptide-17
