How we scored it

Copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate, quaternised with diethyl sulfate; all monomers petrochemical. 0.0.
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

A synthetic copolymer built from petrochemical N-vinylpyrrolidone and dimethylaminoethyl methacrylate monomers, then quaternised with diethyl sulfate. No natural feedstock is used at any stage.

In plain English

A film-forming, anti-static polymer used in hairsprays, gels and conditioners to help hair hold style and resist static. Built entirely from synthetic petrochemical monomers (a methacrylate and a vinylpyrrolidone), quaternised with a petrochemical alkylating agent. Fully petroleum-derived.

CosIng definition: 2-Propenoic acid, 2-methyl-, 2-(dimethylamino)ethyl ester, polymer with 1-ethenyl-2-pyrrolidinone, compd. with diethyl sulphate
