Description of key information

RA (CAS 102-81-8)_OECD 211: EC50 (21 d) = 9 mg/L; NOEC (21 d) = 4.4 mg/L

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
4.4 mg/L

Additional information

There are no studies regarding long-term toxicity to aquatic invertebrates available for Butyldiethanolamine. Therefore, the data on its structural analogue Dibutylethanolamine (DBEA, CAS 102 -81 -8) is taken to evaluate this endpoint (please refer also to read-across statement attached in IUCLID Section 13).

The long-term toxicity towards Daphnia magna has been investigated according to OECD 211 for the read-across substance 2-dibutylaminoethanol (CAS 102-81-8; NITE, 2011). Test organisms were exposed to the test substance for 21 days resulting in a NOEC of 4.4 mg/L (based on reproduction) and an EC50 of 9 mg/L (based on reproduction).
