Polyester-5

Polyester-5 is a synthetic copolymer composed of diethylene glycol, 1,4-cyclohexanedimethanol, and simple esters of isophthalic acid and sulfoisophthalic acid. It is primarily used as a film-forming and viscosity-controlling agent in cosmetic formulations. It appears frequently in setting sprays, mascaras, and hair sprays to help adjust texture and provide a film on the skin or hair.
