Description of key information

Study WAIVED - In accordance with ANNEX IX section 9.3.2, column 2, the study  need not be conducted if the substance has a low potential for bioaccumulation (for instance a log Kow = 3). Kow was experimentally determined (OECD 107) to be in the range of 0.59-1.2. Additional export information provided for a similar material supports the lack of bioaccumulation potential. 
This substance does not meet the criteria of concern for bioaccumulation.

Key value for chemical safety assessment

Additional information

Summary and discussion of 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.
