Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The estimated BCF values of representative constituents range from 3.2 to 19,055 L/kg and 0.4 to 6,304 L/kg Regression based estimation and Arno-Gobas method (upper trophic) (5% lipid normalisation), respectively.

QSAR predictions of bioaccumulation of HFO have also been provided to support the read-across from HFO to registration substance.

Key value for chemical safety assessment

Additional information

Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, the bioconcentration factor (BCF) values of representative constituents of registration substance has been estimated using BCFBAF model, which uses methodology described by Arnot-Gobas et al. (2003, 2006, 2008). The estimated BCF values of representative constituents range from 3.2 to 19,055 L/kg and 0.4 to 6,304 L/kg Regression based estimation and Arno-Gobas method (upper trophic) (5% lipid normalisation), respectively. The predicted BCFs for hydrocarbons are generally overly conservative since biotransformation is not quantitatively taken into account. Therefore, indirect exposure and resulting risk estimates predicted are likely to be overestimated.
