Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Testing on long-term toxicity to sediment organisms has been judged to be not necessary in accordance with column 2 of REACH Annex X and also in accordance with section 3 of REACH Annex XI. In accordance with column 2 of REACH Annex X 9.5.1,the Long-term toxicity to sediment organisms is not proposed because the results of the chemical safety assessment do not indicate any need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. 

Key value for chemical safety assessment

Additional information

Due to the lack of ecotoxicological data for sediment organisms an estimation of the PNEC for sediment was performed using the equilibrium partitioning method (EPM) as recommended in the Guidance on information requirements and chemical safety assessment Chapter R.10 (ECHA, 2008).

On this basis the chemical safety assessment demonstrates that for all uses, the exposure levels estimated for the sediment compartment do not exceed the appropriate PNEC values, the resulting RCR values are all below 0.1 providing a high margin of safety for sediment dwelling organisms.
