How we scored it
Peptide N-capped with hexadecanoyl (palmitoyl, C16 fatty acid) per the IUPAC fragment; amino acids and the palmitic-acid cap are both natural. 737/737 = 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
Made by attaching a palmitic-acid (coconut/palm oleochemical) fatty chain to a synthetic amino-acid peptide. No petrochemical fatty-cap route is used.
In plain English
A small peptide fitted with a natural palm-oil-derived fatty tail to help it absorb into skin. Both the amino acids and the fatty tail come from natural sources.
CosIng definition: Oligopeptide-34 is a synthetic peptide containing 13 amino acids consisting of arginine, aspartic acid, isoleucine, glutamine, leucine, serine, threonine, and tryptophan
