Is Ammonium Cocoyl Sarcosinate natural?

Mostly. Coconut fatty-acid acyl group is oleochemical; sarcosine is usually made from petrochemical chloroacetic acid, and ammonia is natural-gas derived.

How we scored it

Coco (lauroyl-representative) acyl=183.3 Da natural; sarcosine fragment (petrochemical route)=88.1 Da + NH3 for the ammonium salt=17.0 Da, both petrochemical. 183.3/288.4=0.636->0.64.
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

Coconut-derived fatty acid is condensed with sarcosine, typically manufactured from petrochemical chloroacetic acid and methylamine, then neutralised with ammonia. The coco acyl route is well established and dominant.

In plain English

A foaming cleansing ingredient made from coconut-derived fatty acid combined with sarcosine, a small building block usually made synthetically, then neutralised with ammonia. Used in shampoos and cleansers to help create lather.

CosIng definition: Glycine, N-methyl-, N-coco acyl-, ammonium salts
