Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Triethanolamine (TEA, CAS 102 -71 -6) is not PBT or vPvB.
In a CO2 evolution test (West & Gonsior, 1996), TEA was rapidly biodegradable according to GHS criteria. Ready biodegradability was therefore assumed.
The substance is not B or vB as the log Kow is below the critical level of </= 4.5. In addition, the results of a bioaccumulation study similar to OECD 305 showed that TEA does not accumulate significantly in organisms (MITI, 1992). QSAR models support the experimental BCF. The estimated BCF values range from 1.3 to 9.2 based on valid data from five QSAR models.
The substance is not T as TEA does not hold any relevant classification. Chronic effect data are available for Daphnia and algae. As fish is less sensitive than the other trophic levels, this data gap can be regarded to be not relevant for the assessment. The available chronic data are clearly greater than the critical level of 0.01 mg/L, therefore TEA is assumed to be not T.
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.
