Additional information

Data availability

There is no guideline study available for 2 -EHMA. Bacterial toxicity information may be obtained from valid guideline biodegradation studies.


During ready biodegradability tests, no inhibition of bacterial activity was observed for a test substance concentration of 100 mg/L in a 28 d modified MITI (I) test (OECD 301C). This will be carried forward as the NOEC for microbial toxicity.
