Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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-min EC10 value for monoethanolamine in domestic activated sludge is >1000 mg/L, after correction for molecular weight an effect concentration of >5,624 mg/L for monoethanolamine oleate will be used in the assessment.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
5 624 mg/L

Additional information

No respiration inhibition tests with activated sludge are available for monoethanolamine oleate. A non-GLP OECD guideline 209 study with domestic activated sludge is available for one of its starting materials, monoethanolamine (BASF, 1991). 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-min EC10 value is >1,000 mg/L, a safety factor need not to be applied to this value. Instead, the effect concentration will be corrected for molecular weight. The effect concentrations of >5,624mg/L for monoethanolamine oleate will be used in the assessment.
