The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information


No experimental study on bioaccumulation is available on the registered substance. The test material is identified as a UVCB 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 an appropriate read across substance stearyl erucamide (CAS 10094-45-8).

  •  Primary constituent: The BCF was predicted to be 381.4 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 through a supporting study to represent the bioaccumulation potential of the test material. Considering the registered substance properties the experimental log kow > 6,5 according to TG OECD 117 and predicted log Kow = 15,5 according to KOWWIN v1.68. Therefore, the registered substance falls outside the applicability of the model based on the log Kow descriptor (log Kow values > 11,2 max log kow value from training set compounds). The result of the estimation if therefore considered not to be completely reliable.


Considering that the substance does not fulfills the applicability domain of the QSAR, a bioacumulation test on fish is proposed according the TG OECD 305-III (see further explanation below).
