Is Ammonium Caseinate natural?

INCI nameAmmonium Caseinate
CAS9005-42-9
FunctionAntistatic · Hair Conditioning
FeedstockAcid casein from milk dissolved with ammonia.

How we scored it

Casein (milk protein, natural) neutralised with ammonia. Sodium caseinate carries about 1.3% sodium, so the equivalent ammonium content is about 1% of the mass; ammonium from synthetic ammonia is petrochemical (site rule for ammonium counter-ions) → about 0.99.
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

Acid casein from milk dissolved with ammonia.

In plain English

Casein, a milk protein, dissolved using ammonia to form its ammonium salt. Used to help condition skin and hair and reduce static.

CosIng definition: Casein, ammonium salt
