Description of key information

This substance is a reaction mass of dipropylene glycol dibenzoate (DPGDB), diethylene glycol dibenzoate (DEGDB) and triethylene glycol dibenzoate (TEGDB). No aquatic toxicity testing has been performed on the reaction mass itself but data are available for DPGDB, DEGDB and TEGDB individually. All the studies were performed according to international test guidelines and in compliance with GLP.  Short-term toxicity to invertebrates studies were carried out on each of the components of the reaction mass using Daphnia magna.  These data demonstrate that the components of the reaction mass have similar environmental profiles with all EC50 values in the same order of magnitude, >1.0 mg/L and <10 mg/L.  A long-term toxicity to invertebrates study (OECD 211) of the component DPGDB is available. The long-term toxicity to invertebrates test conducted with the component DPGDB is believed to be representative of the reaction mass and fulfills this endpoint for the reaction mass substance.
