How we scored it

All monomers petrochemical: isophorone diisocyanate, dimethylol propionic acid, bisphenol A, propylene oxide, ethylene oxide, PPG. No natural fragment.
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

Synthesised from petrochemical isocyanate, bisphenol A, and alkylene oxide monomers into a polyurethane film-former. No natural-origin route exists for this polymer class.

In plain English

A synthetic film-forming polymer made entirely from petroleum-derived building blocks. Used in hair products to coat strands and help hold style.

CosIng definition: Isophorone diisocyanate, dimethylol propionic acid, and 4,4'-isopropylidenediphenol reacted with propylene oxide, ethylene oxide and PEG/PPG-17/3 copolymer
