How we scored it

Alternating isobutylene/maleic-anhydride copolymer; both monomers petrochemical (butene, maleic anhydride from benzene/butane oxidation) → 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

Made by alternating copolymerisation of isobutylene and maleic anhydride, both derived from petroleum feedstocks. No natural-origin route exists commercially.

In plain English

A film-forming ingredient used in hair styling products for hold. Made from petrochemical isobutylene and maleic anhydride.

CosIng definition: 2,5-Furandione, polymer with 2-methyl-1-propene
