Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Aquatic / sediment bioaccumulation:
Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint has been calculated for representative hydrocarbon structures using the BCFWIN model within EPISuite as input to the hydrocarbon block method incorporated into the PETRORISK model. 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 by PETRORISK are likely to be overestimated.
The compositions of both registrants were available, and both were run in PETRORISK (v7.04) . For the composition 1, the model predicted a BCF of between 0 and 75, whereas for the composition 2, a BCF of between 0 and 29.
For the purposes of PBT assessment, measured bioaccumulation data for representative hydrocarbon constituents have been used as detailed in Section 13, attachment "Evaluation of PBT for Petroleum Hydrocarbons".
EPISUITE v4.11 BCFBAF (2017) estimates are available. For the composition 1, the estimated BCF values of representative constituents range from 13.5 to 70,794 L/kg ww and 0.43 to 2,627 L/kg ww Regression based estimation and Arno-Gobas method (upper trophic) (5% lipid normalisation), respectively, whereas for the composition 2, the estimated BCF values of representative constituents range from 12.9 to 19,055 L/kg ww and 0.43 to 6,304 L/kg ww Regression based estimation and Arno-Gobas method (upper trophic) (5% lipid normalisation), respectively.
Terrestrial bioaccumulation:
Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint has been calculated for representative hydrocarbon structures using default algorithms in the EUSES model as input to the hydrocarbon block method incorporated into the PETRORISK model. 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 by PETRORISK are likely to be overestimated.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
