How we scored it

Built from perfluoropolyether, isophorone diisocyanate and a synthetic hydroxy-acid (DMPA) neutralised with triethylamine. Entirely petrochemical/fluorochemical; 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

A fluorinated polyurethane condensed from a perfluoropolyether, isophorone diisocyanate and dimethylolpropionic acid. No natural-origin route exists.

In plain English

A synthetic fluorinated polyurethane film-former used for water- and oil-repellent finishes on hair and skin. Made entirely from fluorochemical and petrochemical building blocks.

CosIng definition: Polyurethane-27 is a complex polymer that is formed by the reaction of Polyperfluoroethoxymethoxy Difluorohydroxyethyl Ether and isophorone diisocyanate (IPDI) to form a prepolymer. The prepolymer is further reacted with the triethylamine salt of 3-hydroxy-2-(hydroxymethyl)-2-methyl-1-propionic acid
