Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Official classification:
Aquatic compartment
In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1 or Table 3.2: no data found.
Self-classification:
Aquatic compartment
Following CLP (GHS-EU), the substance is not to be classified as acutely or chronically hazardous to the aquatic environment.
Rationale:
- The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
- Chronic data are available only for Daphnia and algae (NOEC > 1 mg/L); therefore, classification is based on the available chronic and acute toxicity data.
- Chronic toxicity data: The NOEC values are greater than 1 mg/L. The substance is rapidly degradable and its experimentally determined BCF is < 500. The chronic data indicate that triethanolamine does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.
- Acute toxicity data: The substance is rapidly degradable, the experimentally determined BCF is < 500. The lowest acute effect value is greater than 100 mg/L. Therefore no long-term hazard exists based on the categories outlined in Table 4.10(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
