Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

To determine the toxicity of 2,2’,2’’-nitrilotriethanol to fish, a non-GLP study similar to APHA method using Pimephales promelas and a flow-through procedure was performed by Geiger et al. (1990). The calculated LC50 value after 96 hours in this study was 11800 mg/l related to the nominal concentrations (confirmed by concentration control analytics). Hence, the chemical is with high probability acutely not harmful for fish.

Other data which are available for 2,2’,2’’-nitrilotriethanol are disregarded and shout not be used for risk assessment purposes mainly due to the insufficient exposure duration.
