Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
According to Annex IX, column 2, section 9.2.1.4. of Regulation (EC) No 1907/2006 the generation of sediment data is not required since the substance has a low water solubility, and, therefore, exposure of sediment organisms is considered unlikely.
However, a chronic sediment ecotoxicology study was undertaken for EPA data requirements and is reported here.
The sediment design was chosen to represent the simulative exposure in the environment due to the substance low solubility and affinity to bind in the sediment (as the result bear out).
The chronic sediment toxicity study demonstrated that there was no negative impact on the non-biting midge exposed to Amides, C16, branched and non-linear over a period of 28 days following a sediment spike dose at the highest level tested, 788 mg/kg dry sediment (achieved concentration) or 1000 mg/kg dry sediment (nominal concentration). Furthermore, the sediment was shown to be the most environmentally relevant compartment following release in the aquatic environment and as the organisms dwell within the sediment until adult emergence, the chronic sediment study is assumed to be the most environmentally protective.
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.
