Is Polyurethane-32 natural?

No. Every monomer (butanediol, ethylenediamine, two diisocyanates, aminoethyl sulfonate) is a petrochemical building block with no natural route.

How we scored it

All five monomers (1,4-butanediol, ethylenediamine, HDI, IPDI, aminoethyl aminoethanesulfonate) are petrochemical = 0/MW = 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

Manufactured by step-growth polymerisation of petrochemical diols, diamines and diisocyanates into a urethane-urea copolymer. No natural-feedstock route exists for this synthetic film-former.

In plain English

A synthetic polymer that helps bind or hold a formula's ingredients together, built entirely from petrochemical building blocks like diisocyanates and glycols.

CosIng definition: Polyurethane-32 is a copolymer of 1,4-Butanediol, ethylenediamine, hexamethylene diisocyanate, isophorone diisocyanate, and sodium N-(2-aminoethyl)-3-aminoethane sulfonate monomers
