Is Hydrogenated Styrene/Butadiene Copolymer natural?

No. Classic synthetic elastomer: both styrene and butadiene are petrochemical cracker products.

How we scored it

Styrene (benzene-derived) copolymerised with butadiene (petrochemical, from steam cracking), then hydrogenated; no natural fragment.
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

Hydrogenated Styrene/Butadiene Copolymer is manufactured from styrene (benzene-derived) and butadiene, both petrochemical products of steam cracking, then hydrogenated. This is a fully synthetic film-forming/thickening polymer with no natural feedstock.

In plain English

A synthetic polymer used to thicken products and form films, similar to synthetic rubber. Made entirely from petroleum-derived building blocks.

CosIng definition: Ethenylbenzene, polymer with 1,3-butadiene, hydrogenated
