Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Standard bioaccumulation studies are not applicable for hydrocarbon UVCB substances. In accordance with Annex XI Section 1.3 testing is not scientifically necessary and the endpoint has been fulfilled using QSAR calculations for relevant constituents. Full justifications for this QSAR are presented in ‘Attached justification’, but in brief these are justified because:

 

-the results are obtained from a QSAR model whose scientific validity has been established

 

-hydrocarbon substances fall within the applicability domain of the QSAR model

 

-results are adequate for the purposes of risk assessment

 

-adequate and reliable documentation is provided

Key value for chemical safety assessment

Additional information

Hydrocarbons, C11-C14, n-alkanes, isoalkanes, <2% aromatics is a hydrocarbon UVCB. Standard bioaccumulation studies for this endpoint are intended for monoconstituent substances and are not applicable for this complex substance. However, this endpoint is characterised using 2 separate quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached in IUCLID section 13).
