PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

The available evidence on degradation is not sufficient for an assessment based on the Annex XIII criteria for persistence (P and vP). As the substance is concluded to be not readily biodegradable (according to OECD criteria), it should be considered as potentially P/vP from a precautionary point of view until further data become available.

However, the mixture is not B/vB (experimentally derived log Kow of -1.44 (pH 12, 23°C) and not T (lowest available chronic value is >>0.01 mg/L). In addition, the mixture as well as its major constituents do not hold a relevant classification.

In conclusion, N3/N4 amine (CAS 68909 -99 -9) is not to be considered as a PBT/vPvB substance.
