Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Relevant key information for classification
Biodegradation: not rapidly biodegradable
- Not readily biodegradable: < 10% - 24% degradation (OECD 301 D, 301 F, DGXI/400/84 EEC 19984, L251, 1984.09.19, Part C, EEC 1984)
- Simulation test in freshwater/sediment system (OECD 308): DT50 = 6630 days
- Simulation test in soils (OECD 307): no decline was observed.
- Bioaccumulation (OECD 305): Lipid normalized growth corrected kinetic biomagnification factor (BMFKgL for 18% lipid food content) = 0.055519
Aquatic acute data
The test item is poorly soluble, thus, according to column 2 of Annex VII and VIII, only long-term studies are relevant.
Aquatic algae: ErC50 (72 h) >100% v/v of a saturated solution (OECD 201, Pseudokirchneriella subcapitata, nominal)
Aquatic chronic data
Aquatic algae: NOEC (72 h) > 100 mg/L (OECD 201, Pseudokirchneriella subcapitata, nominal)
Fish: no effect was observed in a saturated solution- NOEC (33 d) >= 0.021 µg/L (measured)
Aquatic invertebrates: no effect was observed in a saturated solution – EC10 (21 d) > 0.052 μg/L (measured)
Classification justification according to CLP
Based on the data above, the substance is not rapidly degradable in the environment. The substance is characterized by a poor water solubility and high log Koc leading to a low bioavailability. Due to these properties, dietary route is the only way for bioaccumulation or biomagnification. A biomagnification study has been performed that lead to a rapid elimination of the substance from fish tissues. The bioaccumulation potential of the substance is then considered as low.
No toxicity was observed in any available aquatic test. Thus, no classification is required for (Z)-N-octadecyldocos-13-enamide (CAS No. 10094-45-8) according to the Regulation (EC) No.1272/2008 and all further amendments (ATPs).
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.
