Is Cocodimonium Hydroxypropyl Hydrolyzed Keratin natural?

Mostly. Peptide backbone traces to hydrolysed keratin (wool/feather protein); coco-alkyl chain traces to coconut fatty alcohol; the hydroxypropyl linker traces to propylene oxide.

How we scored it

Assume ~1000 Da average peptide (natural) plus one quat site: hydroxypropyl (58 Da, petrochemical) + N(CH3)2 (~28, petrochemical) + coco C12H25 (169, natural) + Cl (35, natural). Natural (1000+204)/1290 = 0.93.
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

Hydrolysed keratin (from wool or feathers) is reacted with a coconut-derived alkyl dimethyl quaternary-ammonium reagent joined via a propylene-oxide-derived hydroxypropyl linker. The protein backbone dominates the molecule's mass, keeping natural-origin content high.

In plain English

A conditioning ingredient made from hydrolyzed keratin protein (often from wool or feathers) modified with a coconut-derived fatty group so it clings better to hair. Mostly protein-derived, with a small synthetic linker.

CosIng definition: Cocodimonium Hydroxypropyl Hydrolyzed Keratin is the quaternary ammonium
