Propylene glycol ethers (PGEs) are comprised of mono-, di-and tri-PGEs and several of their
acetate esters. The nature of the range of applications that use PGEs suggests that there is a
potential for both intentional and unintentional entry of the materials into the environment.
Selected physical/chemical properties, fate characteristics, aquatic toxicity data and
calculated environmental concentrations were used to assess potential risks from the
manufacture, handling, use, and disposal of PGEs. In general, the PGEs are low to …
