Additional information

This substance is a reaction mass of dipropylene glycol dibenzoate (DPGDB) and diethylene glycol dibenzoate (DEGDB). No testing has been performed on the reaction mass itself but data are available for DPGDB and DEGDB individually. All the studies were performed according to international test guidelines and in compliance with GLP.  The acute toxicity studies were carried out on 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. The most sensitive endpoint result obtained for these components has been used as the key value to evaluate hazard and is highlighted below.

The key value is:

Aquatic toxicity to aquatic invertebrates EC50 = 3.05 mg/L (DEGDB)
