Is Polyurethane-17 natural?

No. Every monomer — diols, diisocyanate, triethanolamine and ethylenediamine — is a petrochemical synthetic building block; none derive from plant, animal or mineral feedstocks.

How we scored it

All monomers petrochemical: pentanediol, neopentyl glycol, adipic acid, dicyclohexylmethane diisocyanate, DMPA, triethanolamine, ethylenediamine. 0/total=0.00.
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

Polyurethane-17 is built from petrochemical diols and an aliphatic diisocyanate, then salted with synthetic triethanolamine and extended with ethylenediamine. All monomers are conventional petrochemical polyurethane chemistry with no natural-origin route.

In plain English

A synthetic polymer used to form a flexible film on skin, hair or nails. Built entirely from petrochemical diols, a saturated diisocyanate, and synthetic amines through multi-step industrial polymerisation.

CosIng definition: 2-Methyl-2,4-pentanediol, polymer with 2,2-dimethyl-1,3-propanediol, hexanedioic acid, methylenedicyclohexanediisocyanate and 2,2-di(hydroxymethyl)propanoic acid, hydrolysed, tris(2-hydroxyethyl)amine salts, reaction products with 1,2-ethanediamine
