Is Butylene/Ethylene/Styrene Copolymer natural? NOI 0.00

Q: Is Butylene/Ethylene/Styrene Copolymer natural?

Butylene/Ethylene/Styrene Copolymer has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. Butylene, ethylene and styrene are all petrochemical feedstocks; hydrogenation adds no natural mass to the polymer. An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

How we scored it

All monomers (butylene, ethylene, styrene) petrochemical by default; hydrogenated backbone; no natural fragment → 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

This copolymer is built from petrochemical butylene, ethylene and styrene monomers, then hydrogenated. All feedstocks derive from petroleum cracking.

In plain English

A synthetic rubbery polymer built from petrochemical butylene, ethylene and styrene gases, then hardened by hydrogenation. Used to control thickness and texture in cosmetic formulas.

CosIng definition: Butylene/Ethylene/Styrene Copolymer is a polymer of butylene and ethylene and styrene monomers terminated by hydrogenation
