PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

The PBT criteria are not met. The substane is readily biodegradable and does not persist: the log Kow is 0.5, i.e. far below the criterion of LogKow = 4.5. Regarding acute toxicty to fish, the ECOSAR estimate was LC50(96 hr)= 35 mg/L for the free base and approx. 200 mg/L for the neutral molecule. The neutral molecule is considered to be most relevant for long-term considerations, i.e. 200 mg/L should be taken into consideration. This value is 2,000-fold above the short-term aquatic toxicity criterion in the Guidance document R 11, Table R11-4 for "presumably not T".

No classification is proposed that would suggest PBT classification.
