How we scored it
Palmitic acid (natural C16 fatty acid) amide-bonded to Tetrapeptide-7 (four natural amino acids); both fragments trace to natural feedstocks.
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
The palmitic acid portion comes from vegetable oil or animal fat. The tetrapeptide portion is assembled from amino acids, which are produced by fermentation or protein hydrolysis, both natural processes.
In plain English
A skin-conditioning ingredient combining palmitic acid, a fatty acid from plant oil or fat, with a chain of four amino acids. Both parts trace back to natural fat and fermentation-derived building blocks.
CosIng definition: Palmitoyl Tetrapeptide-7 is the reaction product of palmitic acid and Tetrapeptide-7.
