Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with section 2 of REACH Annex XI the study does not need to be conducted based on weight of evidence.

Key value for chemical safety assessment

Additional information

Testing for sediment toxicity is not considered necessary because:

In accordance with Section 1.2 of REACH Annex XI (testing does not appear scientifically necessary (based on weight of evidence)), the toxicity to sediment organism study does not need to be conducted based on weight of evidence. This is due to

- The substance has a log Kow below 3 and is not expected to exhibit high adsorption or binding (please refer to Sections 4.7 and 5.4.1 of the IUCLID technical dossier for further information).

- It is expected that test organism exposure could not be consistently maintained for test substance in a bioavailable form, or primary degradation products, for the duration of a long-term test, due to very rapid biodegradation and mineralisation of bioavailable alcohol in a sediment-water system (please refer to Section 5.2.2 of the IUCLID technical dossier for further information) 

PNECsediment has been calculated from PNECfreshwater on the basis of the equilibrium partitioning method.
