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 status:
the substance is not PBT / vPvB

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.
