How we scored it
Coconut fatty acid chloride (Cl leaves as HCl, no mass retained) + proline (fermentation amino acid) -> amide; both remaining fragments natural = 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
Made by acylating proline (from protein hydrolysis/fermentation) with coconut fatty acid activated as its acid chloride. No significant petrochemical route is used for either building block.
In plain English
A hair- and skin-conditioning ingredient made by reacting a coconut-derived fatty acid with the amino acid proline.
CosIng definition: Cocoyl Proline is the product obtained by the condensation of coconut acid chloride and Proline
