How we scored it
Polyester polyol + IPDI (both petrochemical) capped with bis-hydroxypropyl dimethicone (silicone = 0.0 by this site's convention); no natural fragment identified.
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 from a petrochemical polyester polyol and isophorone diisocyanate, end-capped with a silicone (dimethicone) segment. No natural-origin component is present.
In plain English
A synthetic film-forming polymer that combines a polyester resin, a petrochemical diisocyanate, and a silicone component.
CosIng definition: Polyurethane-47 is a copolymer made by reacting a polyester polyol with isophorone diisocyanate (IPDI) and then bis-hydroxypropyl dimethicone.
