Additional information

A PNECaquatic of 0.0072 mg/l has been derived from 7.2 mg/l (EC50 value-48 h) for effects on daphnia in an acute toxicity test (the lowest short-term EC50 from each of three trophic levels (fish, daphnia and algae)), divided by an assessment factor of 1000.


No measured data are currently available for marine organisms. Therefore, the marine PNEC is derived from data obtained for freshwater species (EC50 = 7.2 mg/l), applying an assessment factor of 10000 to give PNECseawater = 0.00072 mg/l.


The intermittent releases PNEC is derived from lowest value obtained for freshwater species (EL50 = 7.2 mg/l), applying an assessment factor of 100 to give PNECwater,intermittent = 0.072 mg/l.


The PNEC for waste-water treatment is 10 mg/l based on the test concentration 100 mg/l for the toxicity control in ready biodegradability test not inhibiting degradatin and an assessment factor of 10 is applied.


No toxicity data are currently available for sediment-dwelling organisms. Therefore, it is not possible to determine a PNECsed based on measured data. According to the Technical Guidance Document, PNECsed can be calculated by the equilibrium partitioning method. Hence, PNECsed (freshwater) = 286.66 mg/kg will be used for risk characterisation.


No toxicity data are currently available for marine sediment-dwelling organisms and therefore, it is not possible to determine a PNEC sediment (marine water) based on measured data. According to the Technical Guidance Document, PNEC sediment (marine water) can be calculated by the equilibrium partitioning method. Hence, PNEC sediment (marine water) = 28.66 mg/kg will be used for risk characterisation.


No toxicity data are currently available for effects to soil. Therefore, it is not possible to determine a PNECsoil based on measured data. According to the Technical Guidance Document, PNECsoil can be calculated by the equilibrium partitioning method. Hence, PNECsoil = 57.16 mg/kg will be used for risk characterisation.

Conclusion on classification










Based on the short-term tests on aquatic organisms, the daphnia was the most sensitive to 2-ethylhexyl glycidyl ether in the three trophic level organisms. The EC50 of 7.2 mg/L is the key value for classification.


The test item attained 0 % degradation after 28 days and therefore, cannot be considered as readily biodegradable under the strict terms and conditions of OECD Guideline No. 301F. The log Kow is 3.83 and the calculated BCF value is 355.


Thus, the test substance shall not be classified in accordance with CLP (Regulation EC No.1272/2008) based on available information.
