Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 column 2 of REACH annex IX, further soil degradation testing (required in section 9.2.1.3) does not need to be conducted as the chemical safety assessment does not indicate a need for further investigation. Low exposure is guaranteed, as no sludge application from STP on soil will be done and aerial deposition is negligible.
Furthermore, in the biodegradation test (see section 5.2.1), the substance 1,6-Dichlorohexane is classified as not readily biodegradable in the 10-d-window and after 61 days according to OECD guideline no. 310. However, the biodegradation of the test item came to 54 % after 61 days showing biodegradation with longer exposure times. Thus, further tests on biodegradation will not improve the quality of the risk assessment.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
