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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
PNECaqua (freshwater) and PNECaqua (marine water) were derived based on long-term test results obtained in the frame of aquatic plant and invertebrate long-term tests. As fish is not expected to have a greater sensitivity than the other tested trophic levels, an assessment factor of 10 is therefore proposed for deriving the PNECs.
PNECaqua (intermittent release) is based on the lowest value obtained in the frame of acute ecotoxicity tests.
PNECstp has been derived based upon the Baumann, 1992, study which provided a EC50 result of >100 mg/l. As it is not possible to derive a PNEC value from a greater than value, expert judgement has been applied and an EC50 value of 100mg/l is therefore considered the worst case for toxicity to microorganisms.
PNECsediment and PNECsoil values cannot be derived at the current time due to a lack of physical chemical information (Koc, solubility and vapour pressure).
PNEC oral is not derived as the substance has been demonstrated to be non bioaccumulative.
Conclusion on classification
Based on the results of the acute Daphnia study it is considered that the appropriate classification for DOTE is Aquatic Chronic 3 (H412: Harmful to aquatic life with long lasting effects).
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).
