Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Only low (short-term) toxicity to aquatic organisms was observed for the compound Butyldiethanolamine. Toxic effects observed in the short-term fish test at a concentration of 464 mg/L were rather based on the pH value. Effects in the pH adjusted vessel at 464 mg/L were not observed. With regard to the acute invertebrate test, no toxic effects at all were observed. Referring to the long-term toxicity tests, Daphnia magna with NOEC (21 d) = 4.4 mg/L (based on reproduction) seems to more susceptible than the green algae Pseudokirchneriella subcapitata with a NOErC (72 h) of 25 mg/L.

Conclusion on classification

Regarding all available data of the acute toxicity tests on aquatic organisms and taking into account the provisions laid down in Council Directive 67/548/EEC and CLP Regulation (EC) No. 1272/2008, the substance does not need to be classified for the environment.

Aquatic long-term data are available for two trophic levels (invertebrates, algae). The most sensitive toxicity data was determined for Daphnia magna (NOEC (21 d) = 4.4 mg/L; OECD 211) which does not trigger an environmental classification in terms of chronic effects. Referring to the short-term data, effect concentrations are well above the trigger value of 1 mg/L for acute toxicity. Thus, an environmental classification is neither triggered by short-term nor by long-term toxicity data.
