How we scored it
Where it comes from
Polyester made by condensing petrochemical adipic acid and trimethylpentanediol with a small amount of natural glycerin as the cross-linking branch point. Bio-based adipic acid exists but is not commercially significant; the true monomer ratio is unpublished, so 0.07 is an estimate.
In plain English
A synthetic polyester used as a skin-conditioning ingredient. It is made by joining adipic acid and trimethylpentanediol, both petrochemical, with a small amount of glycerin, which is usually obtained from plant oils.
CosIng definition: Hexanedioic acid, crosspolymer with 2,2,4-trimethyl-1,3-pentanediol and 1,2,3-propanetriol
