Conclusion on classification

For the environmental classification of Triglyme the lowest acute value for aquatic species (EC50 (48h) Daphnia of 5000 mg/L) has to be taken into account (see Section 6.1.3). Due to the low Log Kow of -0.52 (see IUCLID Section 4.7), bioaccumulation is unlikely. Triglyme is not readily biodegradable.

According to the criteria used by DSD 67/648/EEC and 2008/1272/EC Triglyme has not to be classified as dangerous to the environment.
