Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT status:
the substance is not PBT / vPvB

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.
