How we scored it

Copolymer of adipic acid, a diisocyanate, ethylenediamine, hexanediol, neopentyl glycol and a sulfonate amine monomer, all petrochemical: 0/100=0.00.
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

Polyurethane-35 is a fully synthetic polyester-polyurethane built from petrochemical isocyanate, glycol and diamine monomers. No natural-origin production route exists for this film-forming polymer.

In plain English

A synthetic film-forming polymer used to bind and coat, built entirely from petroleum-derived chemical building blocks. It has no plant, mineral or animal origin.

CosIng definition: Polyurethane-35 is a copolymer of Adipic Acid, dicyclohexylmethane diisocyanate, ethylenediamine, Hexandiol, Neopentyl Glycol and sodium N-(2-aminoethyl)-3-aminoethanesulfonate monomers
