Is Acrylamide/Sodium Acrylate Copolymer natural?

Mostly not. The polyacrylate/polyacrylamide backbone is petrochemical; only the sodium counter-ion on the acrylate unit counts as natural mass.

How we scored it

Assumed 1:1 acrylamide (71 Da)/sodium acrylate (94 Da) repeat unit; only Na+ (23 Da) counts natural; 23/165=0.14
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 by radical copolymerisation of petrochemical acrylamide and sodium acrylate monomers. No natural-origin route exists for the polymer backbone.

In plain English

A synthetic polymer made from petroleum-derived building blocks, used to form a film on hair or skin and reduce static.

CosIng definition: 2-Propenoic acid, sodium salt, polymer with 2-propenamide
