How we scored it
Cocoyl (coconut fatty acid, natural) amide-linked to hydrolyzed casein (milk protein, natural), neutralized with potassium (natural mineral counter-ion) → 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 from coconut fatty acid chloride reacted with hydrolyzed casein (a milk protein), then neutralized with potassium hydroxide. No alternative route is in common use.
In plain English
A conditioning ingredient made by attaching coconut-derived fatty acid to hydrolyzed milk protein (casein), then neutralizing with potassium. Used in hair and skin products for a conditioning effect.
CosIng definition: Potassium Cocoyl Hydrolyzed Casein is the potassium salt of the condensation product of coconut acid chloride and Hydrolyzed Casein
