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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The environmental classification of the test substance is currently not harmonized according to the CLP Regulation (EC) 1272/2008.
Based on available acute toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 7.9 mg/L (72-h ErC50 value for the algae P. subcapitata). Based on the available acute data the substance should not be classified for acute toxicity following Annex I of the CLP regulation.
Chronic toxicity data is available for two trophic levels (algae and aquatic invertebrates). In the algal growth inhibition study, the 72h-NOEC for algae was determined to be 1.2 mg/L. Based on the read-across from the analogue substance 3-aminopropyldimethylamine, the 22d-NOEC for daphnia was determined to be 3.64 mg/L. Additionally, the substance is determined to be readily biodegradable and it's log Kow = 0.214. Following Annex I of the CLP regulation, the substance should not be classified for chronic toxicity either.
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.
