Conclusion on classification

For Tetraglyme the lowest acute value for aquatic toxicity is related to Daphnia EC50 (48h) Daphnia of 5000 mg/L and for the chronic toxicity it is the Daphnia NOEC reproduction (21d) of 320 mg/L. Both values - acute and chronic -are above the toxicity level of 100 mg/L which may trigger an environmental classification.

This means that according to the criteria used by the Dangerous Substance Directive (DSD) 67/648/EEC and the 2nd ATP of Classification Labelling and Packaging Regulation (CLP) 2011/286/EC Tetraglyme has not to be classified as dangerous to the environment neither for short-term nor for long-term effects.
