How we scored it
Where it comes from
The itaconic acid comonomer is made by fermenting glucose with Aspergillus terreus, a well-established bio-based route; the majority vinylpyrrolidone and vinyl acetate components are petrochemical. Exact commercial monomer ratio is proprietary.
In plain English
A film-forming polymer used in hairspray, made mostly from petroleum-based building blocks with a small amount of a fermentation-derived acid mixed in.
CosIng definition: Butanedioic acid, methylene-, polymer with ethenyl acetate and 1-ethenyl-2-pyrrolidinone
