Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water and sediment: simulation tests
Administrative data

Description of key information
Waiver. In accordance with Column 2 of REACH Annex IX, the simulation test on ultimate degradation in surface water and the sediment simulation test (required in Sections 9.2.1.2 and 9.2.1.4 respectively) do not need to be conducted as direct or indirect exposure of sediment is minimal.

Additional information
Waiver. In accordance with Column 2 of REACH Annex IX, the simulation test on ultimate degradation in surface water and the sediment simulation test (required in Sections 9.2.1.2 and 9.2.1.4 respectively) do not need to be conducted as direct or indirect exposure of sediment is unlikely. Exposure potential is expected to be minimal as the substance is an intermediate product and manufactured and utilized only at one location in the EU and handled under strictly controlled conditions. Also, the substance’s low hydrophilicity is demonstrated by the very low log octanol-water partition coefficient (Log Kow) of 0.465 at a neutral pH. The solubility of HMBDA has also been determined to be very low, making testing difficult. Therefore, no testing is necessary based on minimal exposure and low solubility. Identification of degradation products (required in Section 9.2.3) is also not necessary.
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.
