Additional information
Conclusion on classification
Fish is the most sensitive species to
dimethyl glutarate with an LC50 (96h) of 30.9 ppm. Short-term effects of
the substance towards daphnia and algae were found greater than 112 ppm
and greater than 85 ppm respectively, based on read across to DBE (EC#
906-170-0). Thus, dimethyl glutarate (DMG) is considered as harmful to
the aquatic organisms.
Dimethyl glutarate is readily biodegradable and has a pKow of 0.49.
