Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 272-712-1 | CAS number: 68909-77-3 The residuum from the reaction of diethylene glycol and ammonia. It consists predominantly of morpholine-based derivatives such as [(aminoethoxy)ethyl]morpholine, [(hydroxyethoxy)ethyl]morpholine, 3-morpholinone, and 4,4'-(oxydi-2,1-ethanediyl)bis[morpholine].

Additional information
Conclusion on classification
The environmental classification of the test substance is currently not harmonised according to the CLP Regulation (EC) 1272/2008. Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 45 mg/L (72-h ErC50 for algae). Based on the available acute data, the substance should not be classified for acute toxicity following Annex I, table 4.1.0 a of the CLP regulation (there are no acute values ≤ 1 mg/L).
In the algal growth inhibition study, the 72-h NOErC for algae was 3.2 mg/L. No other long-term values are available. Following Annex I, table 4.1.0 b (iii) of the CLP Regulation and taking into account the fact that the substance is not rapidly degradable and its log Kow is < 4, the substance should be classified as Aquatic Chronic 3 under the CLP Regulation.
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.
