PBT status:

the substance is not PBT / vPvB

Justification:

Persistence:

The read-across substance did not show degradation in a ready biodegradability test. Furthermore, the substances have very low water solubility. Therefore, the substance is assumed to be P/vP.

 

Bioakkumulation:

Due to a log Kow of -0.24, the screening criterion for not B/not vB was met.

 

Toxicity:

Not T based on acute toxicity tests (NOEC and EC50 > 1 mg/L, no observed effects up to solubility limit)  as well as no classification according to criteria set in Annex XIII of REACH.
