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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The 21-d NOEC for monoethanolamine in Daphnia magna is 0.85 mg/L, after correction for molecular weight an effect concentration of 4.78 mg/L for monoethanolamine oleate will be used in the assessment.

Additional information
No long-term studies with invertebrates are available for monoethanolamine oleate. A GLP-compliant OECD 211 test with Daphnia is available for one of its starting materials, monoethanolamine (NITE, 1996a). Monoethanolamine oleate is the salt of monoethanolamine and oleic acid. As oleic acid is exempted for registration according to Annex V of REACH Directive 2006/121/EC, the focus is only on the monoethanolammmonium cation of monoethanolamine oleate (for more details see reporting format for the analogue approach in Appendix A.2).
The 21-d NOEC is 0.85 mg/L, a safety factor need not to be applied to this value. Instead, the effect concentration will be corrected for molecular weight. An effect concentration of 4.78 mg/L for monoethanolamine oleate will be used in the assessment.
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.
