How we scored it
Palmitoyl cap (palm or coconut fatty acid) plus three amino acids (fermentation or protein hydrolysate); no acetyl or other synthetic cap, so all atoms are natural origin. 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 palm or coconut oil is coupled to a short peptide assembled from fermentation-derived amino acids. The peptide sequence is assumed to use only natural amino acids.
In plain English
A short peptide (three amino acids) joined to palmitic acid, used to condition skin. The fatty acid comes from palm or coconut oil and the amino acids are made by fermentation or from protein hydrolysates.
CosIng definition: Palmitoyl Tripeptide-37 is the product obtained by the reaction of palmitic acid and Tripeptide-37
