PBT status:
the substance is not PBT / vPvB
Justification:

Summary and conclusions on persistence

Based on biodegradation test data, this substance is not expected to be readily biodegradable. This substance appears to fulfill the screening criterion for persistence and is identified as being potentially persistent.

Summary and conclusions on bioaccumulation

Based on the weight of evidence from read across to structurally similar ZDDP substances with BCF data in fish (from Japanese MITI data, US EPA database, CAESAR database), measured Low Kow data, and QSAR predictions, this substance is expected to have low bioaccumulation potential. This substance does not meet the criteria of concern for bioaccumulation.

Summary and conclusions on toxicity

Based on the available acute and chronic toxicity data in algae, daphnids, and fish for the substance itself and a structurally similar ZDDP substance (EC283-392-8), this substance is considered unlikely to have significant effects on aquatic organisms in short and long term scenarios and data demonstrate that this material does not meet the criterion for toxicity as outlined in ANNEX XIII of Regulation (EC) 1907/2006.
