Additional information

PNEC values were established for freshwater and marine environments based on the QSAR estimated 48 hr LC50 of 23.1 mg/L for green algae. The QSAR estimated LC50 was supported by somewhat higher values from acute fish and Daphnia studies. PNEC values were not derived for sediment and soil based on the findings of the Chemical Safety Assessment for Based on the findings of the Chemical Safety Assessment for 1,6 -Hexanediol Diglycidylether.

Conclusion on classification

With acute aquatic EC/LC50 values of less than 100 mg/L,1,6 -Hexanediol Diglycidylether requires the Risk Phrases R52/53, "Harmful to aquatic organisms, and may cause long-term adverse effects in the aquatic environment". .
