Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to fish:

The key value for chemical safety assessment is taken from two experimental results, which confirm: LC50 > 100 mg/L (Bayer AG, 1984) and LC50 = 100 mg/L (ICI Brixham Laboratory, 1986).

No experimental data available for long-term toxicity to fish.

Toxicity to aquatic invertebrates:

The key value for chemical safety assessment is taken from an experimental result by BASF AG (1993).

No experimental data available for long-term toxicity to aquatic invertebrates

Toxicity to aquatic algae and cyanobacteria:    

In a static freshwater toxicity test (BASF AG, 1994) N-Methylaminoethanol was found to be acutely harmful to algae.

Toxicity to microorganisms:

The inhibition of the degradation activity of activated sludge is not anticipated when 2-methylaminoethanol is introduced in appropriate low concentrations.

Additional information

Acute tests on three trophic levels (fish, daphnids, algae) were performed to examine the aquatic toxicity of 2-methylaminoethanol.

Freshwater algae turned out to be the most sensitive species revealing an ErC50 (72h) of 28.1 mg/L.

For the marine phytoplankton species Skeletonema costatum an EC50 (72 h) value of 2.6 mg/L (growth rate) was calculated.

Effects of 2-methylaminoethanol towards Daphnia magna were found in the same range providing an EC50 (48h) of 33 mg/L while the fish test reveals an LC50 (96h) of >100 mg/L.
