Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Dibutylamine (CAS 111 -92 -2) is not PBT or vPvB.
In a modified MITI test, dibutylamine was readily biodegradable (according to OECD criteria, NITE 1991, see IUCLID Ch. 5.2.1) and therefore not P/vP. The substance is not B/vB based on an experimentally derived log Kow of 2.1 (pH 12.0, 23 °C, BASF SE, 2010, see IUCLID Ch. 4.7). In addition, in a weight-of-evidence approach, several QSAR models showed that dibutylamine does not accumulate significantly in organisms. The estimated BCF values range from 5.75 to 46.0 L/kg based on valid data from five QSAR models (see IUCLID Ch. 5.3.1). The substance is also not T since the lowest available chronic value is >> 0.01 mg/L and the substance holds no relevant classification.
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.
