Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

This endpoint has been calculated for representative hydrocarbon structures including the substances in the C9-14 Aliphatics (≤ 2% aromatic) category using the BCFWIN v2.16 model within EPISuite 3.12 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. For the purposes of PBT assessment, measured bioaccumulation data for representative hydrocarbon constituents including the substance have been used as detailed in PETRORISK spreadsheet attached to IUCLID section 13.

The QSAR used to calculated the BCF of C9-14 Aliphatics (≤ 2% aromatics) followed the Reach guidance indications (R7.10.3.2) and so is deemed suitable for the assessment of bioconcentration.

The calculated BCF of decane is 144.3 L/kg. This value indicates that decane is not to be considered as a bioaccumulable substance.

The calculated BCF of undecane is 337.8 L/kg. This value indicates that undecane is not to be considered as a bioaccumulable substance.

The calculated BCF of 790.9 L/kg indicates that dodecane does not belong to bioaccumulable substances.

The calculated BCF of tetradecane is 962.9 L/kg. This value indicates that tetradecane is not to be considered as a bioaccumulable substance.
