Is Polyurethane-34 natural?

No. Every building block, the diols, diacid, diisocyanate and synthetic amines, is a petrochemical commodity chemical with no natural-origin fragment.

How we scored it

All monomers petrochemical: hexanediol, neopentyl glycol, adipic acid, hexamethylene diisocyanate, aminoethyl-aminoethanesulfonic acid, ethylenediamine. No natural fragment present. 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 polyurethane resin built entirely from synthetic petrochemical diols, diacid, diisocyanate and amine monomers. No natural feedstock is used in any step.

In plain English

A synthetic film-forming polymer used to bind and hold ingredients together, for example in mascaras or styling products. It is built entirely from man-made chemical building blocks, not plant or mineral matter.

CosIng definition: Polyurethane-34 is a complex polymer that is formed in a multi-step reaction. A copolymer of Hexanediol, Neopentyl Glycol, and Adipic Acid is reacted with hexamethylene diisocyanate. The resulting polymer is further reacted with N-(2-aminoethyl)-3-aminoethanesulfonic acid and ethylenediamine
