Is Polyester-10 natural?

No. All four monomers - hexanediol, neopentyl glycol, adipic acid, pyromellitic dianhydride - are commercially petrochemical feedstocks.

How we scored it

Hexanediol 0 + neopentyl glycol 0 + adipic acid 0 + pyromellitic dianhydride 0 (all petrochemical condensation monomers) → 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

Polyester-10 is a condensation polymer made from petrochemical hexanediol, neopentyl glycol, adipic acid and pyromellitic dianhydride. No commercially significant bio-based route exists for this monomer combination.

In plain English

A synthetic polymer that forms a flexible film on skin or hair. It is built from petroleum-derived building blocks in a chemical plant, not extracted from any plant or animal source.

CosIng definition: Polyester-10 is the product of the thermal condensation of Hexanediol, Neopentyl Glycol and Adipic Acid and pyromellitic dianhydride
