Bioaccumulation

The test material is identified as a UVCB substance therefore estimation through Quantitative Structure–Activity Relationship (QSAR) assessment is not an appropriate approach for the substance as a whole. To address the bioaccumulation endpoint a QSAR assessment, using the Estimation Programs Interface (EPI) SuiteTM BCFBAF v3.01, was completed as part of a weight of evidence approach on the primary constituent of the substance and 2 appropriate read across substances oleyl palmitate (CAS RN number 16260-09-6) and stearyl erucamide (CAS RN number 10094-45-8).

  •  Primary constituent: The BCF was predicted to be 381.4 L/kg ww by BCFBAF v3.01 (EPISUITE, 2013).

  • Oleyl palmitate: The BCF of oleyl palmitate was predicted to be 113.1 L/kg ww by BCFBAF v3.01 (EPISUITE, 2013).
  • Stearyl erucamide: The BCF of stearyl erucamide was predicted to be 113.1 L/kg ww by BCFBAF v3.01 (EPISUITE, 2013).

 

Based on the above information, as a worst case example, the primary constituent presented the highest BCF value of 381.4 L/kg ww. This value has therefore been used to represent the bioaccumulation potential of the test material

Based upon the estimated BCF of 381.4 L/kg ww, the test material is not expected to bioaccumulate in the environment.
