Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

PNEC aquatic values were not generated because testing indicates the substance has negligible solubility in water and is not toxic to 3 aquatic organisms. Negligible water concentrations are expected based on minimal partitioning to water in the environment and high binding to particulates with subsequent settling. No hazard was identified for water or air. The PNEC STP is 1 mg/L, based on a NOEC of 10 mg/kg sludge. The PNEC freshwater sediment is 100 mg/kg dw, based on 2 long term tests in sediment organisms, while the PNEC marine sediment is 10 mg/kg dw using these results. The PNEC soil is 156 mg/kg soil dw based on data in 3 trophic levels.

Conclusion on classification

Classification of DBDPEthane as an environment hazard is not justified.
