Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes is an extremely complex hydrocarbon UVCB. The substance is comprised of 23 different categories of components. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance.

As a result, the potential bioaccumulation of representative structures from each category of components identified in Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes has been calculated using the BCFBAF model (v3.01) found in the US EPA’s EPISuite (v4.11) group of QSAR models. The calculated BCF values (Arnot-Gobas Upper Trophic) ranged from 1 to 2278 L/kg wet-wt.

Based on the results, only few structures of Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes (C12 iso alkane, C12 alkene and C14 linear alkane in the whole carbon range of the categories) meet the Bioaccumulative (B) criteria.
