How we scored it

Crosslinked copolymer of methyl methacrylate and ethylene glycol dimethacrylate; both monomers petrochemical (acrylate family, glycol) → 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

Polymerised from petrochemical methyl methacrylate crosslinked with ethylene glycol dimethacrylate. No natural monomer route exists.

In plain English

A film-forming plastic-type polymer made from petrochemical acrylic building blocks, crosslinked into a network. Entirely synthetic, chemically similar to Plexiglas.

CosIng definition: 2-Propenoic acid, 2-methyl-, 1,2-ethanediyl ester, polymer with methyl 2-methyl-2-propenoate
