How we scored it
Palmitoyl C16 (oleochemical) amide-linked to a tripeptide of fermentation-derived amino acids; coupling reagents and protecting groups leave no mass. 1.00 (sequence not resolved).
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 is peptide synthesis from fermentation-derived amino acids with palmitic acid from palm or palm kernel oil attached at the N-terminus. No non-natural amino acid is expected, but the exact sequence was not confirmed.
In plain English
A small lab-made chain of three amino acids with a palmitic acid fatty tail attached. The palmitic acid tail makes the peptide more oil-soluble, so it can be used in creams as a skin-conditioning ingredient. The amino acids and fatty acid come from fermentation and palm oil.
