How we scored it
Palmitoyl C16H31O from vegetable oil plus a peptide of amino acids from fermentation; condensation water lost; all fragments natural, so 1.0. Peptide sequence unresolved.
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 couples palmitic acid from vegetable oil to a peptide built from fermentation-derived amino acids. A C-terminal amide or non-proteinogenic residue in the unresolved sequence would lower the value slightly.
In plain English
A signalling-peptide ingredient with a palmitic acid fatty tail, used to soften and condition skin and nails. The peptide is assembled from amino acids and the fatty tail comes from vegetable oil.
CosIng definition: Palmitoyl Oligopeptide-70 is the product of the reaction of palmitic acid and Oligopeptide-70
