Is Acrylates/Stearyl Methacrylate/VP Copolymer natural?

Mostly not. Only the stearyl alcohol part of stearyl methacrylate is oleochemical; vinylpyrrolidone, acrylic acid and methacrylate backbones come from petrochemical acetylene, propylene and isobutylene.

How we scored it

Assumed 30% stearyl methacrylate (C22H42O2 338.6; stearyl-O 269.5 natural, methacryloyl 69.1 petrochemical), 40% vinylpyrrolidone, 30% acrylic units: 0.30 x 269.5/338.6 = 0.24.
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

Dominant route: free-radical copolymerisation of petrochemical vinylpyrrolidone and (meth)acrylic monomers with stearyl methacrylate made from oleochemical stearyl alcohol. Composition is not published, so the stearyl share is an assumption; no alternative route is known.

In plain English

A synthetic polymer built from acrylic monomers, stearyl methacrylate and vinylpyrrolidone. It forms a flexible film, helps hold hair, and stabilises or thickens emulsions. Nearly all of it comes from petrochemical monomers; only the stearyl chain is plant-derived.

CosIng definition: Acrylates/Stearyl Methacrylate/VP Copolymer is a copolymer of vinylpyrrolidone, stearyl methacrylate, and one or more monomers of acrylic acid, methacrylic acid or one of their simple esters.
