How we scored it
Myristoyl C14H27O (~211 Da, oleochemical) plus a nonapeptide of amino acids (fermentation or hydrolysate); amide links only, no acetyl cap. Sequence not supplied: 1.00.
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: solid-phase peptide synthesis from fermentation-derived amino acids, then coupling to myristic acid from palm kernel or coconut oil. Reagents and resins leave no mass in the product.
In plain English
A fatty-acid-linked signal peptide: nine amino acids joined to myristic acid, used in skin-conditioning products. The fatty tail comes from coconut or palm kernel oil and the amino acids from fermentation or protein sources.
CosIng definition: Myristoyl Nonapeptide-3 is the product of the reaction of myristic acid and Nonapeptide-3
