Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 30-d NOEC for monoethanolamine in the freshwater fish Oryzias latipes is 1.2 mg/L, after correction for molecular weight an effect concentration of 6.75 mg/L for monoethanolamineoleate will be used in the assessment.

Key value for chemical safety assessment

Additional information

No long-term studies with fish are available for monoethanolamine oleate. A GLP-compliant OECD 210 Early Life Stage test with Japanese killifish (Oryzias latipes) is available for one of its starting materials, monoethanolamine (NITE, 2006). 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 30-d NOEC is 1.2 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 6.75 mg/L for monoethanolamine oleate will be used in the assessment.
