Is Trimethylpentanediol/Adipic Acid Copolymer natural?

No. Both monomers, adipic acid and trimethylpentanediol, are conventional petrochemical building blocks with no significant bio-based cosmetic supply.

How we scored it

Adipic acid (petrochemical, cyclohexane oxidation) + 2,2,4-trimethyl-1,3-pentanediol (fully synthetic, isobutyraldehyde-derived) = 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

Adipic acid is manufactured from petrochemical cyclohexane; trimethylpentanediol is synthesized from petrochemical isobutyraldehyde. The resulting polyester has no natural-origin fragment.

In plain English

A synthetic polymer used as a skin-conditioning film-former in cosmetics. Built entirely from petrochemical building blocks.

CosIng definition: Hexanedioic acid, polymer with 2,2,4-trimethyl-1,3-pentanediol
