Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Type:
BAF
Value:
70.8 L/kg

Applicant's summary and conclusion

Validity criteria fulfilled:
not applicable
Conclusions:
The bioconcentration factor is considered to be 70.8 L/kg based on calculation by the EPI modelling programme.
Executive summary:

Removal of mineral oil is not possible without degrading the chemical structureof the substance. It was therefore considered acceptable to create a weight of evidence approach based upon Quantitative Structural-Activity Relationship (QSAR). The QSAR model of choice was the EPI Suite v4.0 published by the United States Environmental Protection Agency, which has estimated the bioconcentration factor to be 70.8 L/kg.
