Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

biodegradation in water: sediment simulation testing
Data waiving:
exposure considerations
Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of sediment is unlikely
Justification for type of information:
In accordance with column 2, section of REACH Annex IX, simulation testing on degradation in surface water is waived because the test substance is highly insoluble. In accordance with column 2, section 9.2 and section of REACH Annex IX, sediment simulation testing is waived. The Chemical Safety Assessment indicates the direct and indirect exposure of sediment is unlikely. ECHA Chapter R.7B and R.7C guidance states that if the PEC/PNEC ratio is below 1, then no risk for the compartment is indicated, that the information available may be sufficient to conclude the assessment, and there is no need to perform further tests. Additionally, ECHA Chapter R.7B guidance states that if the substance is not considered a PBT or vPvB candidate, then it is considered not necessary to conduct further testing on the compartment. Therefore, on the basis of a lack of potential exposure and low risk demonstrated by RCRs of less than 1 based on EUSES modelling, waiving is justified.
