Is Cocodimonium Hydroxypropyl Hydrolyzed Casein natural?

Mostly. A natural protein hydrolysate carrying a small number of quaternary ammonium groups. The peptide, any fatty chain and the chloride are natural; the methylated nitrogen and the hydroxypropyl linker are petrochemical.

INCI nameCocodimonium Hydroxypropyl Hydrolyzed Casein
FunctionAntistatic · Hair Conditioning
FeedstockProtein hydrolysate reacted with a glycidyl or chlorohydroxypropyl…

How we scored it

Per ~1,000 Da of peptide (natural protein hydrolysate) one quaternary group: coco alkyl (lauryl proxy) C12H25 169.3 Da (natural) + chloride 35.5 Da (mineral) natural; N + 2×CH3 44.1 Da and hydroxypropyl C3H6O 58.1 Da petrochemical; 1204.8/1306.9 = 0.92. Substitution level is supplier-dependent; the same model is used for every quaternised protein in this wave.
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

Protein hydrolysate reacted with a glycidyl or chlorohydroxypropyl quaternary ammonium reagent.

In plain English

A conditioning ingredient made from milk-protein hydrolysate (casein) modified with a coconut-derived, positively-charged group. Used in hair and skin products to help conditioning and reduce static.

CosIng definition: 2-Hydroxy-1-propanaminium, N,N-dimethyl-N-(coco-alkyl)-, 3-hydrolyzed casein derivs., chlorides
