Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

As the substance is poorly soluble in water, most of the studies are performed using Water accomodated fractions (WAFs) and all the results are based on nominal loadings. Thus, the values indicated below as NOECs are actually NOELRs (No observed effect loading rates). No study could lead to the calculation of EL50.

Key value for chemical safety assessment

Additional information

Fourteen study reports were available for this end-point, all dealing with the toxicity of the substance “Hydrocarbons, C14-C18,n-alkanes, isoalkanes, cyclics, < 2% aromatics” on algae growth rate. All the studies used the marine speciesSkeletonema costatum. None of the studies allowed calculating 48h-EL50 that was never reached. All LL50 are superior to 10000 mg/L based on WAF studies.
