How we scored it
Palmitoyl C16H31O (palm or coconut fatty acid) amide-bonded to collagen peptides; both building blocks natural, leaving groups carry no mass; 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
Dominant route: collagen hydrolysate is acylated with palmitoyl chloride made from palmitic acid under alkaline conditions; the chloride leaves as salt. No petrochemical fragment is retained.
In plain English
Collagen broken down into small peptides and bonded to palmitic acid, a fatty acid from palm or coconut oil. It gives a conditioning, cleansing ingredient that softens and reduces static in hair and skin products. The collagen usually comes from animal or fish by-products.
CosIng definition: Collagen, hydrolyzed, 1-oxohexadecyl derivatives
