How we scored it

All monomers petrochemical: PPG-17, PPG-34 (polypropylene glycols), isophorone diisocyanate, dimethylolpropanoic acid -> 0/total = 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

Built from petrochemical polypropylene glycol chains and isophorone diisocyanate, both derived from crude-oil feedstocks. No renewable or mineral component is used.

In plain English

A film-forming ingredient used in styling and long-wear cosmetic products. It's a fully synthetic plastic-type polymer built from petrochemical polypropylene glycols and isocyanates.

CosIng definition: Polyurethane-4 is a copolymer of PPG-17, PPG-34, isophorone diisocyanate and dimethylolpropanoic acid monomers
